摘要 |
<p>In a poppet check valve (10), a cylindrical inlet passage (46) connects axially with a valve chamber (56) and a shoulder (50) at the juncture between the inlet passage and the chamber defining an annular valve seat (54). A relatively thin disc-like valve element (60) in the valve chamber (56) has a generally circular imperforate central section (66) of a diameter greater than the diameter of the inlet opening (52) but less than the diameter of the valve chamber (56). A pluarlity of legs (68) extend radially from the periphery of the central section (66) into sliding engagement with the inner wall (48) of the valve chamber (54). A circular seal element (72) is joined to one side of the central section (66) and is maintained under a bias toward the seat by a coil spring (62) mounted in the valve chamber (56). Between the spring (62) and the valve element (60) is a stop member (64) including a plurality of radially spaced, axially extending force applying elements (98) engaging the central section (66) of the valve element (60). The stop member (64) also includes a guide surface (95) radially outwardly of the force-applying elements (98) for sliding engagement with the wall (48) of the valve chamber (56) at a location axially spaced from the valve element (60).</p> |
