Abstract

578,843. Pump governors. LUCAS, Ltd., J., and IFIELD, R. J. Oct. 15, 1942, No. 14459. [Class 135] A fuel pump governing means of the kind including a spring-loaded piston or diaphragm adapted to actuate the output controlling means of the pump subject to unrestricted fluid pressure on one side and on the other to fluid pressure supplied through a restricted passage and exhausted through a leak-off valve responsive to any predetermined condition associated with the system has a variable volume chamber arranged to communicate with the controlled side of the piston or diaphragm. As shown in the Figure, a rotor a houses a series of spring- loaded plungers c actuated by a swash-plate e adjusted by a spring-loaded piston q. The pump outlet k is connected by a passage l to one side of the piston and by a restricted passage t with the control side of the piston.. A bleed-off passage from the control chamber is controlled by a hinged valve v actuated by a diaphragm adjustably loaded by a spring and subject to the outlet pressure of a centrifugal pump formed in the rotor a.. The control chamber is also connected by a passage 7 with a variable volume chamber 9 housing a spring-loaded piston 10 to compensate undesired pressure or volume fluctuations set up in the liquid delivered by pump. In a modification a spring-loaded non-return valve is inserted in the passage 7 to allow free flow into the chamber and a restricted return flow. In place of a piston-controlled variable-volume chamber, a corrugated flexible chamber or a diaphragm loaded by a spring or gas under pressure may be used.
