Abstract
739,729. Jet-propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 7, 1953 [April 11, 1952], No. 9436/53. Class 110 (3). [Also in Group XXIX] The flow of fuel to a pulsatory jet-propulsion unit is cut off in the event of cessation of operation of the unit by a valve which is held open against a spring by a pressure differential which exists only whilst the unit is functioning. The valve R (see Group XXIX) is inserted in the fuel line 15, 10 and has a pressure-responsive actuator connected by a pipe 19 with a point 32 in the intake E in which a sub-atmospheric pressure obtains during operation. The actuator is also subject, on its opposite side, to atmospheric pressure and has a valved connection 17 with a source of compressed air for initially opening the valve. In modifications, the pipe 19 may lead to a point at which pressure is above atmospheric, e.g. to a tapping in a hookshaped tubular member in front of the entrance to the intake E, or to the combusiton chamber. Also, instead of one of the pressures applied to the valve being atmospheric both may be obtained from different points in the jet-propulsion unit. The valve R may also be responsive to fuel pressure, tending to close with increase of that pressure. Specification 660,144, [Group XXIX], is referred to.
