Japanese Patent JPH06506284

Kind Code:

A

Abstract:

A pressure relief valve (14, 14A) has a reciprocable valve member (34, 34A) for seating on an annular seat face (66,66A) of a nozzle assembly (38,38A). The nozzle assembly (38,38A) has an inner seat ring (40,40A), a radially outer anchor ring (42,42A), and a flexible connecting member (44,44A) extending in a generally radial direction between the outer peripheral surface (64) of the seat ring (40,40A) and the inner peripheral surface of the anchor ring (42,42A). Upon seating or reseating of the valve member, (34,34A), seal face (36,36A) contacts the seat face (66,66A) of seat ring (40,40A) and flexible connecting member (44,44A) flexes upon relative movement of the seat ring (40,40A) after initial contact of the valve member (34,34A) against the seating ring (40,40A) thereby to act as a shock absorber for absorbing impact forces.
