Abstract

1,169,909. Axial piston pumps and motors. MESSIER. Nov.29, 1966 [Dec. 3, 1965], No.53330/66. Heading F1A. The pump or motor cylinder block 21 is supported for rotation by a bearing 25 between the block and a support 24 coaxial with the shaft 4. The bearing 25 surrounds the position of intersection of the resultant of piston thrust forces perpendicular to the axis of the pump or motor and this axis. The shaft 4 is coupled to the block 21 by a sleeve 23 having a relatively long portion 23a splined to the shaft and a relatively short portion 23b splined to the block. The bearing 25 may be a journal or fluid bearing. The inclination of the cam plate 28 is variable by a piston 38 subject to the pump or motor pressure under the control of a spring-biased valve member (37, Fig. 8, not shown). The cylinder block may be formed in two parts (3a, 3b, Fig. 4, not shown), the part (3a) engaging the face valve (2) being of relatively soft material and the part (3b) engaging the drive sleeve (11) and the bearing (10) being of relatively hard material. Leakage liquid within the pump casing is discharged through a passage (45, Fig. 6, not shown), in the cam plate bearing (44a). The cylinders may be inclined to the axis of the block. The cylinder block support may be solid and the drive shaft may pass through the face valve.
