摘要： A diaphragm type valve device comprising a housing having a pair of valve chambers separated by a diaphragm piston and connected to respective fluid pressure input ports, oppositely disposed valve seats fixed in the housing in facing relation to each side of the diaphragm piston and connected to respective output ports, a pair of valve members reciprocably disposed in a central bore in the diaphragm piston and being axially biased in opposite directions by a spring compressibly installed in the central bore between the valve members, one or the other of the valve members being seatable on one or the other of the valve seats when the diaphragm piston is axially displaced by dominating pressure acting on one or the other side thereof, and stop rings concentrically fixed in the central bore adjacent the respective ends thereof for limiting axial displacement of said valve members by the spring to a spaced-apart distance somewhat greater than the fixed axial distance between the valve seats. A spring for biasing the diaphragm toward one of the valve seats, if desired, may be compressibly disposed in one of the valve chambers between the diaphragm piston and an end wall of the housing.

摘要： An elastomeric sleeve is inserted in the hole in the cock body which has multiple passages for the fluid. A plug, which may be positioned to connect selected passages, is placed within the sleeve in the hole. Either the contacting surfaces between the hole and sleeve or the rubbing surfaces between the sleeve and plug are tapered. A spring, seated on the base of the body or a plug flange, exerts upward pressure on the sleeve to assure tight contact between adjacent surfaces to eliminate fluid leaks.

摘要： A force transfer mechanism including a force lever through which an input force is transmitted to an output member with mechanical advantage only after the output member encounters sufficient resistance to overcome a friction connection between an input member and the output member indicative of the input member having moved from a retracted position to an operative position. The resultant movement of the input member relative to the output member in the absence of the frictional connection therebetween allows the input member to engage the end of force lever that is normally spaced-apart therefrom and to accordingly drive the output member with a force corresponding to the input force multiplied by the ratio of the force lever only in the operative position of the input member.
