Abstract
A swash plate compressor comprises a swash plate located for rotation in a housing and a compression unit that forms a part of the housing. The compression unit has cylinder bores that guide pistons in reciprocation as the swash plate rotates. Each cylinder bore has a cross section formed of any other closed curve than a circle. The closed curve is defined by curve elements and straight elements.

A swash plate compressor comprising:
- a housing;
- a rotatable main shaft extending in said housing;
- a swash plate mounted on said shaft and rotatable together with said shaft;
- and
- a compressor unit adapted to carry out a suction process and a compression process for a working fluid as the swash plate rotates,
- said compressor unit including a plurality of pistons arranged adjacent to one another in the rotating direction of said swash plate and adapted to reciprocate in an axial direction of said shaft as said swash plate rotates, and a plurality of cylinder bores capable of individually receiving the corresponding pistons and guiding the pistons in reciprocation,
- each said cylinder bore having a cross section formed of any other closed curve than a circle, the closed curve including curve elements and straight elements, each of the straight elements connecting each two adjacent curve elements.
