Abstract

1343055 Flame sensor valve MALONEYCRAWFORD TANK CORP 24 May 1971 46913/71 Divided out of 1343053 Heading F4T [Also in Division F2] In a pressure responsive valve A, (Division F2) expansion of pressure fluid in a sealed bellows 60 on heating of an attached sensor bulb 90 by a burner flame causes an extension tube 62 movable with the bellows 60 to open a valve 72, preferably having a resilient seat 70, against a biasing spring 74. This allows gas to flow from inlet 80 vai intermediate passage 82 and outlet 84 to, for example, another valve or an alarm in response to the presence or absence of the burner flame. A conduit through the tube 62 is closed by the valve 72 when the bellows 60 is expanded but permits the escape of exhaust gas via openings 64 and exhaust connection 86 when the bellows 60 contracts.
