Abstract

632,261. Fluid-pressure servomotor-control systems. HOBSON, Ltd., H. M., SIMPSON, T., GREENLAND, L. S., and EDWARDS, T. Aug. 19, 1947, No. 22989. [Class 135] [Also in Group XXVIII] A pump 70 is actuated by a radially-acting cam (see Group XXVIII) and its delivery is adjusted by moving the cam along a shaft by the piston 16 of a fluid-pressure servomotor. The pump 70 is fed by a gear pump 13 through a pipe 72 from which a pipe 20 fitted with a restriction 21 leads to the cylinder 17 containing the piston 16. The piston 16 is loaded by a spring 18 and the pressure in the cylinder is adjusted, to vary the position of the piston 16, by moving a leak-off valve 24 by lever 29. The cylinder 17 is arranged co-axial with the pump cam-shaft and within circle of pump cylinders.
