Abstract
The invention relates to an axial piston displacement compressor, comprising a drive shaft (12), a disc (14) which is mounted on the drive shaft in such a way, that it can be pivoted about a pivotal axis (C) and at least one piston (18) which is provided with sliding blocks (20) that slide on a runway on the disc (14). The invention aims to reduce the maximum effective surface pressure between the disc (14) and the sliding blocks (20). To this end, the pivotal axis (C) of the disc (14) is located eccentrically in relation to the central plane of the disc.

Axial piston compressor with a drive shaft (12) for a disc (14) that is mounted on the drive shaft in such a way that it can be tilted relative to the drive shaft about a pivotal axis (C), and at least one piston (18), wherein the pivotal axis (C) of the disc (14) is disposed eccentrically with respect to the mid-plane of the disc,
- characterized in that the piston (18) is provided with at least two sliding blocks (20) that move the disc (14) axially on a slideway, arranged such that the piston (18) encloses the sliding blocks (20) in a C-shaped structure, and that the position of the pivotal axis (C) relative to the mid-plane of the disc is on the side that faces the piston (18), so that the disc (14) can be independently tilted relative to the sliding blocks (20) in such a way that the slideway of the sliding blocks projects beyond the edge of the disc only slightly or not at all whereby a constant pivotal axis is defined for the disc.
