Abstract
730,086. Liquid-pressure engines. UNITED AIRCRAFT CORPORATION. March 13, 1951 [Sept. 27, 1950], No. 6003/51. Class 69 (2). [Also in Group XXVIII] In a revolving radial cylinder hydraulic motor, the rotor B is mounted on a pintle A, provided with a sleeve 11, and drives the shaft 25 through an Oldham type coupling 21, 22. Three rows of pistons D, operating in cylinders in the rotor, engage a track ring 15 carried by a support ring E mounted on a pivot 33. The support ring is adjusted by the supply pressure acting on a piston 64 that is connected to a roller 67, engaging a cam surface 68, and also a strut 65 engaging a projection 50 on the support ring which is loaded by an adjustable compression spring 70. The force transmitted from the piston 64 is modified so that the moment acting on the support ring is a function of the eccentricity of the ring; various shapes of the cam 68 may be used to vary the relationship between the supply pressure and the eccentricity of the support ring. A tension spring 75 may be combined with the spring 70 to obtain the desired loading of the support ring. The pivot 33 is mounted on a support 34 and both parts have curved engaging surfaces to correct misalignment between the rotor and the pintle; the pivot is adjustable by the screw 37. The inlet and outlet ports in the pintle each have two openings 6 or 12 which co-operate with the three openings leading to a row of cylinders. The pump may be supplied with sealing devices as described in Specification 730,094, [Group XXVIII].
