A compressor (1) with at least one piston (9) movable in a cylinder (10), a drive shaft (2) and a wobble plate arrangement (4, 5) between piston (9) and drive shaft (2), having an inclined plate (4) with variable inclination angle, and with a spring arrangement (17; 41 to 43), acting on the wobble plate arrangement in the direction of a minimum displacement. Such a compressor should also be able to operate at higher pressures without increasing its size, e.g. to enable the use of CO.sub.2 as refrigerant. For this purpose the spring arrangement (17; 41 to 43) acts on the wobble plate arrangement (4, 5) in the area of the radial edge.

Compressor

A compressor is disclosed, in particular for air-conditioning systems in vehicles, having at least one piston movable in a cylinder, a drive shaft and a wobble plate arrangement between the piston and the drive shaft. To improve the efficiency and to reduce leaks, the wobble plate arrangement comprises a swash plate, on which a wobble plate is rotatably mounted. Between the wobble plate and the piston is arranged a bearing which allows movement of the wobble plate relative to the piston in the circumferential direction.
