Abstract

604,168. Liquid-pressure engines. VICKERSARMSTRONGS, Ltd., NAYLOR, J. C., and FIELDHOUSE, J. N. Dec. 19, 1944, No. 31416/45. Divided out of 604,117. [Class 69 (ii)] [Also in Group XXVIII] In an axial type hydraulic motor the inclined plate engages a plurality of slippers corresponding in number with the number of pistons, each being connected to an associated piston and provided with means for utilizing the reaction or pressure of the hydraulic fluid in the cylinders to impart hydraulic fluid cushioning or pressure between the inclined plate and the slippers in such a manner that a hydraulically balanced and self-lubricating driving connection between the pistons and the plate is obtained. The pistons 12 reciprocating in the cylinders 3 are formed with ball ends 13 which seat in slippers 15 having bases formed with polished surfaces making sliding contact with the opposed polished surface of a track ring 20 set in the inclined plate 19. Each said surface of the slippers is formed with a concentric recess 16 in the centre of which is a small aperture 17 communicating with an axial bore 18 in the appropriate piston, this bore extending through the piston so as to be exposed to the working pressure of the hydraulic fluid in the appropriate cylinder. The pump shown has valve means similar to that described in Specification 604,117.
