1. Field of the Invention
The invention relates to jet receivers for electrohydraulic servovalves or the like and refers more specifically to a method of producing a laminated receiver plug assembly and the laminated receiver plug assembly produced by the method.
2. Description of the Prior Art
In the past, jet pipe receivers have generally been solid members having passages machined therein which passages usually have extended first axially into one end of the receiver structure and then radially through opposite sides thereof. The axially extending portions of the receiver structure passages have generally been round in cross section and separated by an extremely thin divider portion at the point of receiving fluid from a jet pipe. The divider portion has necessarily been required to be constructed to close tolerances. Such tolerances are difficult to maintain, particularly in view of the relatively small dimensions of some jet pipe receivers, their passages, and the divider portion between some passages therein. Further, the round cross section of the axially extending portions of the prior receiver structure passages have made prior jet pipe receivers sensitive to nozzle misalignment in the direction of extent of the divider portion.
Therefore, a good deal of waste material and machining hours have been accumulated in production of prior jet pipe receivers due to the tolerance limitations and size of such receivers and the usual method of production of the receivers by conventional machining. Also, the jet pipe receivers produced by conventional machining from solid metal have not been as uniform and therefore as efficient as desired and have been more expensive than necessary.
