in fig1 and 2 there is shown in a side view two different positions for an arrangement according to the invention . the basic design of the steering arrangement is made in a conventional way . thus , a steering arrangement known in itself is disclosed that comprises a steering device 6 that is pivotable about a vertical shaft 5 , which is fixed in the water jet &# 39 ; s outlet - part 20 which in its turn is attached to the ship &# 39 ; s transom . furthermore , this basic construction consists of a beam arrangement fixed at each side of the steering device and in which there is arranged a hinge 12 for suspension of a lever arm 17 of a reversing device 7 . in fig1 the reversing device is shown in its inactivated mode , that is , a position for full speed ahead . in fig2 the reversing device is shown in an activated mode , where the jet stream thus is diverted for the achievement of a reversing force . the novel feature of this design is the arrangement of the hydraulic cylinders 2 , 3 , 9 that act on steering device 6 , and reversing device 7 respectively . the cylinders 2 , 3 , 9 are arranged within a closed space 1 above the basic construction . the space is box - shaped and delimited by a number of plates 1 a - 1 g . the front plate 1 e is meant to be fixed to the jet unit &# 39 ; s attachment flange 11 , while the rear plate 1 g is arranged at a sufficient distance from the front plate 1 e to be able to hold the whole cylinder 9 ( for the reversing device 7 ) which is placed furthest back of the cylinders 2 , 3 , 9 which are about the same size . the lower plate 1 f is partly arranged essentially horizontally and holds the upper end of the vertical shaft 5 for the steering device 6 . the upper plates 1 a , 1 b are arranged so that sufficient space is obtained for hydraulic cylinders with associated surrounding equipment , eg ., hydraulic conduits and positional measuring equipment 22 . a yoke - shaped swinging arm 4 is fixed at and pivotable together with the vertical shaft 5 . two shaft pivots 14 a , 14 b ( see fig3 ) are arranged on top of this swinging arm 4 , and the front end 3 a , 2 a of the hydraulic cylinders 2 , 3 for turning the steering device 6 are articulately arranged at said shaft pivots . moreover , there is at said swinging arm 4 arranged two attachment handles 15 for pivotable suspension of the hydraulic cylinder 9 by a shaft 13 that is fixed at said hydraulic cylinder 9 . thus , the hydraulic cylinder 9 for the reversing device 7 is connected to the shaft 5 so that it swings along with it in its movements . the centre line c 2 of the shaft 13 for suspension of the cylinder 9 is arranged such that it crosses the centre line c 1 of the vertical shaft 5 . moreover , the centre line c 3 for the hydraulic cylinder 9 , ( see fig4 ) is arranged to cross the centre line c 1 of the vertical shaft 5 . this suspension means that the relative position of the reversing device 7 related to its hydraulic cylinder 9 , is not influenced by the steering device &# 39 ; s 6 relative position . thus the reversing device ( 7 ) does not change its position relative to the steering device even if the steering device is turned to different positions , which would be the case if the suspension of the cylinder 9 were not according to this invention . furthermore , it is shown that the piston rod 9 a for acting on the reversing device 7 protrudes from the box - shaped space 1 through a sealed slit 16 which is arranged in the back end 1 g of the box - construction . preferably the slit 16 is sealed to hinder water from flowing into the sheltered space 1 and also to hinder possibly leaking oil from flowing out from it . the slit 16 enables the hydraulic cylinder 9 to perform a pivoting movement about the shaft 13 , which is necessary since the hinge 21 for the piston rod 9 a at the linkage arm 17 is moving along a circular arc , 21 a meaning that the hydraulic cylinder 9 must be able to pivot upwards and downwards respectively , when the piston rod 9 a is moving . the respective front end 3 a and 2 a of the turning hydraulic cylinders 2 , 3 are articulately connected about a shaft pivot , that is arranged at the means of attachment element 11 a and 1 b respectively , which in their turn are firmly attached to the jet unit &# 39 ; s attachment flange 11 . above and in - between said means of attachment elements 11 a and 11 b respectively , but within said space 1 , a distribution chamber 18 for hydraulic oil is arranged , from which the hydraulic conduits 19 for supply and removal respectively , of oil for the hydraulic cylinders emanates . due to this arrangement , both distribution chamber 18 and hydraulic conduits 19 will be placed in a sheltered position within said space 1 . fig3 and 4 show a steering arrangement according to the invention seen from above . in fig3 the steering arrangement is shown in a swung out position , the steering device 6 being positioned obliquely related to the body &# 39 ; s extension to be able to perform a yaw . in fig4 the steering device 6 is shown in a folded in position , i . e . for driving straight ahead when the reversing device 7 is inactivated . the position in fig4 is achieved by means of the hydraulic cylinders 2 , 3 being positioned with each end 2 b , 3 b of the piston rods , in a common plane which is parallel with the jet unit &# 39 ; s attachment flange 11 . from this position , by pushing out the piston rod of the lower ( in the figure ) hydraulic cylinder 3 and at the same time pressing the piston rod of the upper ( in the figure ) hydraulic cylinder 2 , the swinging arm 4 is swung about the vertical shaft 5 , so that the steering device 6 is angled relative to the jet unit &# 39 ; s attachment flange 11 which leads to a yaw . owing to the invention it is gained a sheltered location of the hydraulics without having to use long and cumbrous linkage mechanisms . also , the module principle , according to the invention entails , that existing arrangements can be modified in a simple way , so that sheltered location of hydraulics may be installed afterwards . in fig5 , there is schematically shown a modification according to the invention . there is shown in a side view an outlet part 20 , and steering device 6 with substantially the same design as described above . in other aspects the figure shows merely those elements that have been changed in relation to the above described preferred embodiment . an important difference is that the hydraulic cylinder 9 is fixedly attached to the attachment device 15 a , ( which preferably is in the form of a flange ) at the top of the vertical shaft 5 . the hydraulic cylinder 9 is arranged with a corresponding flange 9 b , in order to be able to securely attach the hydraulic cylinder 9 to the attachment device 15 a . accordingly the piston rod 9 a may merely be moved within one and the same horizontal plane , corresponding with the extension of the centerline c 3 of the piston rod 9 a . in order to compensate for the movement along a curve 21 a of the hinge 21 for the linkage arm 17 ( not shown ) there is arranged an intermediate link 17 a . this link 17 a is pivotally attached to both the arm - hinge 21 at one end and to the piston hinge 9 c at the other end . as described above the hydraulic cylinder ( preferably also the other cylinders , which are not shown ) is sheltered within a substantially closed space 1 , having a horizontally extending slit 16 at one end for the piston rod 9 a , such that the rod 9 a may freely move in / out and sideways . also in this embodiment the slit 16 preferably is sealed . in this connection it is advantageous to not having any pivoting movement of the hydraulic piston rod 9 a in the vertical plan , i . e . the piston rod 9 will move within the same horizontal plan in relation to the slit 16 independent of the reversing device 7 . the invention is not limited to what has been described above but may be varied within the scope of the claims . thus , it is realized that it is not necessary with two hydraulic cylinders to act on the swinging arm but that in certain cases it is quite adequate with only one hydraulic cylinder . however , two symmetrically placed hydraulic cylinders for the turning is preferable , not at least for reliability -/ safety reasons . furthermore , it is realized that the principle also may be used , by means of linkage mechanisms , to connect in parallel several adjacently arranged steering arrangements . the expression “ connected to the attachment flange 11 of the water jet unit ” may not be narrowly interpreted , but it is realized that “ the connection ” may be ( and in many cases are ) indirect , i . e . the connection may be formed through one or several intermediate elements . however , it is important the this “ connection ” is designed so that it may transmit the forces needed , which in the normal case i . a means that it is essentially rigid . it is also realized that “ the connection ” may be made at the transom stern instead of the jet unit . the main thing is that “ the connection ” is made to one of the ships solids . it should be understood that the closed space 1 not in all cases need to be sealed , by means of a sealing arrangement in the slit 16 . moreover it should be understood that if a seal is used it will not need to totally seal - off the closed space 1 in all kind of installations . in some installations it may be sufficient to , hinder a substantial flow of water in and out of the close space 1 . further it should be understood that the expression slit shaped opening ( 16 ) shall be construed in a broad manner , including alternatives where the opening is half - closed / open by the use of overlapping , flexible or movable , seal elements that allow the piston to be moved there between .
