Abstract

1439536 Hydraulic pumps or motors KLOCKNER-WERKE AG 23 July 1973 [12 Aug 1972] 34923/73 Heading F1A In a rotary cylinder block swash-plate pump or motor having axial pistons 5 provided with slippers 7 for engaging the swash-plate bearing surface 12 and wherein liquid is supplied to a central pressure pocket 14 in each slipper through a longitudinal bore 10 in the piston and a restricted bore 13 in the slipper, the annular land 17, 18 surrounding each pocket 14 is provided with an annular groove 16 in communication with the pocket through a spiral groove 19. Each piston end 6 is partspherical and is received in a complimentary socket 9 in the slipper 7, the diameter of the end 6 being approximately the same as the pocket 14. The ratio of the diameters of the pressure pocket and of the piston lies within the range 1:2.25 to 1:1.4. The annular groove 16 is at least as great as the diameter of the piston, the latter being approximately half the diameter of the slipper.
