ABSTRACT:
A compact bistable, magnetically operated fuel valve embodies an upper portion comprising a pair of similarly poled and spaced apart permanent magnets defining vertical side walls of an enclosure space which is completed by a pair of pole plates sandwiching the permanent magnets therebetween. The pole plates provide pole faces at their opposite ends and the two sets of pole faces define air gaps. Within the space there is located an armature of plate like form centrally mounted on an upstanding flexure tube. A valve actuating rod is connected at one end to the free end of the flexure tube and projects therethrough downwardly into a valve block. The valve block presents at least one fuel chamber provided with means for supplying pressurized propellant thereto and is provided with oppositely directed fuel outlets to which oppositely directed thrusters are connected. The armature is held in one of two rocked positions in opposition to the centering action of the flexure tube, the free ends of the armature being located in the air gaps. A pair of coils surround the armature and a pulsing mechanism is connected to the coils sequentially to energize them to oppose oppositely directed flux fields therein and allow the armature to snap from one rocked position to the other. The energizing pulses are controlled in relative phase to control the net thrust produced by the oppositely directed thrusters.
