Abstract

927,926. Liquid-pressure engines. PREROVSKE STROJIRNY N.P. VYZKUMNY USTAV STAVEBNICH A KERAM. STROJU. Nov. 30, 1959 [Dec. 3, 1958], No. 40548/59. Class 69 (2). An hydraulic motor comprises stationary components consisting of a shaft 1, supply and discharge conduits 18, 19 and a cylinder block 2 having a plurality of cylinders 3, each cylinder having a reciprocable piston 5 and a port 8, and rotatable components consisting of a fluid control member 24 to register the conduits alternately with the ports 8, and a housing 10 which reacts to the movement of the pistons during their working strokes. The control member 24 has, on one face, grooves 25, 26 which communicate by way of passages 27, 28 in a member 22 with the conduits 18, 19 respectively, and, on the other face, a plurality of recesses 29 which are alternately connected to the grooves 25, 26 by passages 31, 32 and co-operate with the ports 8. The control member is rotated by lugs 34 on the housing and connects the ports 8 of the cylinders to the conduits 18, 19 so as to reciprocate the pistons 5, the radially-outer ends of which engage bars 6 carrying rollers 7 co-operating with eccentric or wave-shaped cams 11 on the housing 10. The member 22 is urged to the left by a spring 35 and fluid pressure from the inlet 16 to prevent leakage at the surfaces 9, 23 between the cylinder block, control member 24 and member 22. The surface 23 may be of spherical shape. The supply may be connected to the conduit 19 to reverse the direction of rotation of the motor. In other embodiments, the conduits may be formed in the shaft and the cylinders be arranged with their axes parallel to the shaft, the pistons acting against a swash-plate secured to the housing.
