    摘要： A valve assembly of a filter element has a valve plunger with a valve stem provided with a coupling section and a valve plate connected to the valve stem and designed to close a valve opening. The valve assembly has a spring element with a spring section for generating a restoring force and a holding section for mechanically coupling the spring element to the coupling section of the valve plunger. The valve stem is enclosed at least partially by the spring section. The holding section and the coupling section engage each other such that the spring section generates a restoring force along a center axis of the valve assembly that forces the valve plate against a rim of the valve opening.

    摘要： In a liquid drip prevention valve, an input port is formed in the upper face of a flow passage block, and an output port is formed in the lower face, which opposes the upper face of the flow passage block. In addition, a valve chamber is formed on a side face of the flow passage block, and an air block abuts the side face. Furthermore, a diaphragm valve makes contact with a valve seat when pressure is applied with respect to a back side chamber of the diaphragm valve and separates from the valve seat when the back side chamber is brought to negative pressure, thus forming the liquid drip prevention valve.

    摘要： The disclosure is of a ball check valve comprising a valve body with a flow passageway completely through it. The flow passageway is counterbored at one end to form a conical seat and at the other end to form a radial shoulder. The valve member comprises an integral ball and stem of an elastomer. The stem is inserted through the valve passageway and stretched to function in the nature of a tension spring, with lateral extensions on the stem seated against the radial shoulder of the valve body.

    摘要： A device for insuring a positive fluid seal between a float collar valving element and valve seat therein is disclosed. The device comprises a rubberlike tension strap or compression steel spring positioned within the float collar valve assembly for urging the valving element against the upper valve seat. Fluid pressure from above the valve assembly will overcome the force exerted on the valving element by the urging device and permit fluid to flow in a downwardly direction through the float collar valve assembly. However, when this fluid pressure above the float collar is reduced, the urging device overcomes the force exerted thereby and again urges the valving element in positive sealing engagement with the upper valve seat to preclude flow of fluid in an upperwardly direction back through the float collar valve assembly.
