ABSTRACT:
In a wobble plate piston-drive mechanism, the inclination of the ring-shaped wobble plate is adjustable through an articulated connection of the wobble plate to the shaft by means of an axially movable guiding device and a driver arm that reaches into an engagement cavity of the wobble plate at a radial distance from the shaft to transmit the driving force from the shaft to the wobble plate. The driver arm head and/or the engagement cavity are shaped so that the force-transmitting contact between the driver arm head and the annular wobble plate is moved away from the area where the engagement cavity has its minimum wall thickness. This prevents or reduces deformation of the gliding surface of the wobble plate and thus makes the mechanism run more smoothly.
