摘要：
A flow control device illustrated as a pressure relief valve (10, 10A) has a reciprocable valve member (22, 22A) for seating on a face (20, 20A) of a fixed seat ring (18, 18A). The valve member (22, 22A) includes a hub (36, 36A), an outer seal ring (38, 38A), and a flexible connecting member (40, 40A) extending between and connecting the seal ring (38, 38A) and the hub (36, 36A). Upon seating or reseating of valve member (22, 22A) seal ring (38, 38A) contacts fixed seat ring (18, 18A) and flexible connecting member (40, 40A) flexes upon relative movement of the hub (36, 36A) after initial contact of the seal ring (38, 38A) with the fixed seat ring (20, 20A) to act as a shock absorber for absorbing impact forces.
