referring to fig1 - 3 of the drawings , a first embodiment of the invention generally comprises a valve body 10 , control sleeve 12 and handle 14 . valve body 10 may be conventionally formed as a brass extrusion which is subsequently machined . control sleeve 12 is formed of a rigid but resilient elastomeric plastic material such as shell kraton 7820 ( 90 durometer ) or monsanto &# 34 ; santoprene &# 34 ;. the handle may be formed of abs plastic . valve body 10 contains inlet and outlet bores 16 , 18 , respectively , and an upper neck portion 20 containing sleeve bore 22 . as best shown in fig2 and 3 , the inner end of inlet bore 16 , at its intersection with sleeve bore 22 , terminates in a transverse wall having vertically spaced inlet passage 24 and bypass passage 26 . control sleeve 12 is open at its bottom end and has two diametrically opposite ports 28 , 30 in its cylindrical side wall . upon rotation of control sleeve 12 by handle 14 , ports 28 and 30 can be selectively brought into or out of registry with inlet passage 24 and outlet bore 18 . rotation of handle 14 is transmitted to sleeve 12 by means of driving formation 32 on the upper end of the sleeve , which in snugly received within driving slot 34 on the underside of the central portion of the handle . the upper neck portion 20 of the valve body 10 has a beveled rim which terminates in a circumferential retaining lip 36 which cooperates with resilient inwardly projecting retaining formations 38 on handle 14 , as will be further described below . downwardly projecting stop flanges 40 on handle 14 engage shoulders 42 on the exterior of valve body 10 to positively stop rotation of the handle and sleeve at the extreme opened and closed positions of the sleeve . the orientation of slot 34 and stop flanges 40 assures that parts 28 and 30 will be properly aligned at assembly . the outer diameter of sleeve 12 is selected to snugly but slidably received within bore 22 of valve body 10 . as shown in fig2 and 3 , which illustrate a position approximately half way between the quarter - turn extremes of full open and full closed , line pressure for inlet bore 16 pressurizes the interior of sleeve 12 by means of bypass passage 28 . this internal pressure exerts a radially outward pressure against the cylindrical walls of sleeve 12 , assuring that no leakage occurs through sleeve ports 28 and 30 or between the sleeve side walls and sleeve bore 22 . when sleeve 12 and handle 14 are rotated to the full open position , sleeve ports 28 and 30 will be fully aligned with inlet passage 24 and outlet bore 18 of valve body 10 , establishing direct flow across the sleeve and through the valve . as a result of the novel handle construction and its means of retention to the valve body through retaining lip 36 and retaining formations 38 , no supplementary fastening means are required to secure the handle to the sleeve or the handle - sleeve assembly to the valve body . the resilience of the handle permits the handle to be forced downwardly over retaining lip 36 , while the wide lip 36 prevents axially upward hydraullic pressure within the sleeve from forcing the handle and sleeve upward out of sleeve bore 22 . the cooperating cylindrical surfaces of the inwardly facing formations 38 and the outer diameter of neck 20 permit rotation of handle 14 without interfering with the axial retaining function of elements 36 and 38 . referring now to the angle stop embodiment of the present invention illustrated in fig4 - 6 , corresponding elements carry reference numerals corresponding to those shown in fig1 - 3 , with the exception that the three - digit reference numerals all begin with the numeral one . as will be seen , the outlet bore 118 is at right angles to the inlet bore 116 of valve body 110 . control sleeve 112 is axially aligned with inlet bore 116 and the open lower or inner end of sleeve 112 is in continuous alignment and direct communication with inlet bore 116 . sleeve 112 may have either one or two ports 128 , although only one is required to establish communication between the interior of the sleeve and outlet bore 118 in the open position of the valve . the optional use of a second diametrically opposite port permits the same sleeve to be employed in either a straight - through stop value , such as shown in fig1 - 3 , or in an angle stop valve as shown in fig4 - 6 . also , the second port eliminates the need for careful attention to proper angular orientation of the sleeve at the time of assembly . while handle 14 , such as is illustrated in the embodiment of fig1 - 3 , could be employed in the embodiment of fig4 - 6 , an alternative 114 is shown for purposes of illustration . it is to be understood that either form of handle could be used for both the straight - through and angle stop forms of valves the appropriate cooperating formations on the outer end of the respective control sleeves 12 , 112 . as shown in fig4 - 6 , the driving formations which cause sleeve 112 to rotate when handle 114 is rotated comprise a pair of inwardly directed flanges 132 on the underside of the handle which are initially assembled to cooperating slots 134 at the outer end of sleeve 112 . after this preliminary sub - assembly is made , the handle - sleeve assembly is axially inserted into sleeve bore 122 of valve body 110 . retaining lip 136 on valve body neck portion 120 cams outwardly the resilient retaining formation 138 of handle 114 , until the assembly is fully inserted , whereupon formations 138 are firmly seated beneath retaining lip 136 , as in the embodiment of fig1 - 3 . stop portions 140 on the underside of the handle engage stop shoulders 142 on the valve body when the handle and sleeve have been rotated to their full open and full closed position . in both embodiments , only a quarter - turn of the handle and sleeve is necessary to go from the open to closed positions . the embodiment of fig4 - 6 also permits a complete valve to be assembled utilizing only three components , without supplementary seals or fasteners . is is contemplated that the novel configuration of the embodiments disclosed herein produce negligible wear and leakage . however , should a problem arise , the low cost of the assembly could permit the entire valve to be disposed of , if desired . in the event that a manufacturer wished to facilitate service rather than disposal of the entire assembly , the handle 114 of the embodiment of fig4 - 6 can be readily removed from retaining lip 136 by resiliently bending the outer portion of the handle to a concave shape to thereby expand the gap between retaining formations 138 and permit them to be moved past retaining lip 136 . as a further alternative , it is contemplated that the handle may be formed integrally with the control sleeve , utilizing the handle - retaining means described above . this invention may be further developed within the scope of the following claims . accordingly , the above specification is to be interpreted as illustrative of only a few operative embodiments of the present invention , rather than in a strictly limited sense .
