Abstract

577,778. Fluid-pressure servomotors. NASH, A. G. FRAZER-. Feb. 18, 1938, No. 5156. [Class 135] [Also in Group XXVIII] In a swash-plate pump in which the angularity of the swash - plate 18 is caused to vary in accordance with the delivery pressure of the pump, the inlet and delivery sides 2, 3 of the pump are connected respectively to the smaller and larger ends of a spring-loaded piston valve 52 in a cylinder 51, the valve 52 uncovering a port 50 to allow pressure fluid to pass into a control cylinder 48 having a piston 47 to move the swashplate in opposition to its spring 43.
