Abstract

767,804. Revolving-cylinder pumps. VICKERS, Inc. July 9, 1953 [July 10, 1952], No. 19028/53. Class 102(1). [Also in Group XXIX] A hydraulic pump or motor of the swashplate type, in which a cylinder barrel 34 is splined at 78 to a drive shaft 76 and abuts a stationary valve plate 44, has the drive shaft 76 supported in a bearing 90 in the housing of the pump or motor, the bearing being situated between the spline connection 78 and the juncture of the cylinder barrel and valve plate. A collar 68 is splined to the cylinder barrel 34 and has a spherical surface 66 contacting a conical bore in a sleeve 60 carrying a cage 58 in which are mounted shoes 42 carrying the spherical ends of pistons 38. Springs 72 in recesses 74 in the cylinder barrel press against the collar 68 to urge the shoes 42 against a thrust plate 46 and also to urge the cylinder barrel against the valve plate 44. Specifications 645,420 and 767,805 and U.S.A. Specification 2,313,407 are referred to.
