Abstract

565,334. Liquid-pressure engines. VICKERS-ARMSTRONGS, Ltd., HOLDEN, W. C., and NAYLOR, J. C. June 25, 1942, No. 8756. [Class 69 (ii)] [Also in Group XXVIII] In a hydraulic pump or motor comprising radial cylinders containing pistons 4 in driving or driven connection with an eccentric 10 on a driving or driven shaft 11, the shaft is supported by a bearing 15 carried by a distance-piece 17 attached to one end of the pump or motor body 1 and by a bearing 16 carried by the body itself or by a valve chamber or end cover 23 attached to the other end of the body whilst the valve chamber has fluid admission and exit ports 24, 25 and contains a self-sealing valve 21 of the kind described in Specification 503,148 actuated by an eccentric on the shaft and controlling the flow of fluid through common fluid admission and exit passages 22 leading to the cylinders. The cylinders may comprise bores in sector-shaped blocks 3 secured in position by studs 2, whilst the pistons may have part-spherical inner ends 6 to engage corresponding seatings'in slippers 8 which engage a ring 9 carried by needle bearings 12 on the eccentric 10, undesired outward radial movement of the pistons being restrained by angled retaining rings 13 engaging transverse pins 5 on the pistons. In a modification, the cylinders consist of borings in the body 1, and alternative methods of coupling the pistons with the eccentric are described and illustrated.
