Abstract

418,013. Hydraulic transmission of power. RUSSELL, W. S., and HILL, D. M. J., 4, Sarah Street, Leicester. May 25, 1933, No. 15119. [Class 69 (ii).] . Hydraulic mechanism for reciprocating a piston m, comprises a constant delivery pump d and a variable delivery pump i, the liquid from which is controlled by a pair of separate or interconnected valves at k. The forward stroke is effected by allowing the liquid from the pump i to pass to the cylinder through a pipe e, the piston is stopped by closing the pipe e and allowing the liquid from the pump i to return to a reservoir b, and the return stroke is effected by the pump d, the pipes e, x being open. A relief valve or valves j are provided, and a second piston p may be operated under the control of a valve r. The valves at k may consist of a rotary valve with a cam on its spindle for operating a lift valve.
