Abstract (en)
[origin: EP0935069A2] Novelty - The plate cam (8) has an average pressure aperture (23). Seen in direction of rotation (38) of the cylinder drum relative to the plate cam, the aperture is located between a high pressure aperture (18) in the cam, and a first dead center position (21), where the axial movement direction of the pistons is reversed. A control unit with regulator valves (24) regulates the pressure at the average pressure aperture to a set average pressure level (MD), between the low pressure (ND) at the low pressure aperture (19) and the high pressure (HD) at the high pressure aperture.
