Abstract
In an air-conditioning compressor with a revolving wobble plate driven by a driving shaft, the variable piston stroke height is regulated by directing pressure medium to flow from the high-pressure outlet compartment to the piston-drive compartment and/or from the piston-drive compartment to the intake suction compartment of the compressor. The driving shaft has a tubular end portion extending into a recess of the cylinder head. The medium flow from the high-pressure area to the piston-drive compartment is routed along the outside of the end portion, while the flow from the piston-drive compartment to the intake area is routed through the hollow channel inside the end portion. A flow-resisting element is arranged between the outside of the end portion and the wall of the recess in the cylinder head, so that the flow resistance towards the cylinder head is significantly greater than in the direction towards the driving compartment.
