Abstract
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.
