JPH04502802A  
JPH04143197A
PURPOSE: To lighten shift operating force by drilling an oil balancing path that diverges from an oil supply path in a stem valve in the switching valve device of a hydraulic clutch, and performing selection of the position of an opening...  
JPH047409Y2  
JPH041426Y2  
JPH03284464A
PURPOSE: To prevent a sealant from being encroached by a valve seat even in such a case as doing a pumping action by installing a valve, connecting the side of a pressure chamber of a valve element to the side of a reservoir according to...  
JPH03282084A
PURPOSE: To cause smooth movement of a displacement means by means of a low force by providing the displacement means at its interior with a communicating hole for intercommunicating a second fluid passage and a part of a control chamber...
