    • 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.
    • 在具有由驱动轴驱动的旋转摆盘的空调压缩机中,可变活塞行程高度通过使压力介质从高压出口室流到活塞驱动室和/或活塞 - 驱动室到压缩机的吸气室。 驱动轴具有延伸到气缸盖的凹部中的管状端部。 从高压区域到活塞驱动室的介质流沿着端部部分的外侧布置,而从活塞驱动室到进气区域的流动通过端部内部的中空通道。 在端部的外部和气缸盖中的凹部的壁之间布置有流动阻力元件,使得朝向气缸盖的流动阻力显着大于朝向驱动室的方向。
