Title: Improvements in and relating to safety valves
IPC: G05D16/06
Filed: 1925-06-04
Abstract: 256,736. Schatz, E. June 4, 1925. Safety-valves. - A safety-valve for use with a pressure-regulator has a valve member and seat independent of the pressure-regulator pressed into mutual contact under normal circumstances mainly by the pressure prevailing in the chamber to be protected, release of excess pressure being effected by arresting the movement of one of the two elements after a concerted movement of both of them. The valve member k is normally held in contact with a perforated seating diaphragm c by a light spring n assisted by the pressure in the casing. The diaphragm is adjustably loaded by a spring j acting through a tubular member f having a shoulder g adapted under normal conditions to rest on a shoulder h and so take the load off the diaphragm. Should the pressure become excessive the spring j is compressed and the diaphragm moved away from the member k whose continued movement is arrested by a shoulder m engaging the casing.
