In a unit having a booster pump connected in the supply to the cylinders (17) so that the piston (16) is held in engagement with the driving eccentric (13) by the supply pressure, without the use of springs, a slipper (31) with a hydrostatic pad (36) engages the eccentric (13) and has a socket (30) which receives a ball (29) on the end of the piston. The ball (29) is held in place by spring ring (32). To minimize misalignment of the slipper (31) with the eccentric (13) when the pump is not running, a centering spring (39) with fingers (40) is arranged in the bore (37) supplying the pad (36). To avoid shocks and damage resulting from misalignment mating surfaces (34 and 35) are spherical rather than cylindrical. |
