Abstract
An axial piston machine, especially an air-conditioning compressor for motor vehicles, including a power unit which is rotatably driven by a shaft and in which the rotary movement is converted, via a swash plate, a wobble plate, or a pivot ring, into a fore-and-aft movement of pistons that suction in and compress pressure media. The shaft is mounted in a forward, first axial bearing, among other things.
Claims8
An axial piston machine comprising:
- a shaft;
- a power unit rotationally driven by the shaft, the rotational motion in the power unit being converted via a converter into a reciprocating motion of pistons which draw in and compress pressure media;
- the shaft supported in a front first axial bearing;
- and
- an elastic, resilient, one-piece axial fixing and bearing device preloading the shaft against the front first axial bearing and acting on the shaft in a rear end area opposite the front first axial bearing;
- wherein the axial fixing and bearing device is braced axially against the shaft and axially against a housing component, the housing component being a valve plate device, a cylinder block or a cylinder head,
- wherein the axial fixing and bearing device has a first axial annular contact surface for the shaft and a second axial annular contact surface for the valve-plate device, the cylinder block, or the cylinder head, the first or second axial annular contact surfaces joined by a third annular surface curved in a tulip shape and resilient in the axial direction.
