摘要： A pressure relief valve (61) including a body (110, 114) interconnecting an inflatable volume (20a,22a) with a source of pressurized fluid (30) and the atmosphere. A pair of valve members (120, 122) cooperate to allow controlled inflation and deflation of the volumes (20a,22a) as well as to close off the fluid path between the source and the volumes and vent fluid from the volumes to the atmosphere in order to achieve at least two predetermined fluid pressures in the volume.

摘要： An improved fluid flow valve (10) for a fluid flow control system. The flow valve (10) includes a flow-regulating assembly (40) having a housing (44) having a piston bore (15) within which is slideably disposed a piston-like member (42). The piston-like member (42) has a primary flow passage (52) and at least one secondary flow passage (54) formed therein. A first portion (42a) of the pistonlike member (42) is configured for mating with a seat (46) of the housing (44), and a resilient member (48) biases the piston-like member (42) away from the seat (46). When at least a predetermined fluid pressure differential exists, the first portion (42a) mates with the seat (46) and causes the at least one secondary flow passage (54) to be at least substantially closed such that fluid can substantially flow only through the primary flow passage (52).
