Zusammenfassung:	884,558. Valves. GENERAL ELECTRIC CO. Ltd. July 16, 1959 [Aug. 12, 1958], No. 25888/58. Class 135. A pressure relief valve comprises a first chamber 6 having an inlet 2 and outlet 3, a closure member 7 normally biased e.g. by spring 14 on to its seat 8 and means e.g. bellows 12 defining with member 7 a second chamber 19 connected at 16 to an independent pressure supply, to control the valve opening independently of the downstream pressure. The outlet contains a restriction at 17 to maintain substantially inlet pressure in chamber 6 and the member 7 is connected to a dashpot 9, 10.
