PISTON COMPRESSOR Russian patent published in 2012 - IPC F04B35/04 

FIELD: machine building.

SUBSTANCE: compressor has cylinder (15) where compressor chamber (14) of circular cross-section is made, and inlet and outlet openings (18, 19) are made in front wall (12) of cylinder (15) for a compressible medium, and it also has piston (32 ) that reciprocates in compressor chamber (14), and which carries displacement protrusion (33) on its surface facing butt end (12), which enters outlet opening (18) in piston dead centre (32) position. The longitudinal axis of cylinder (15) passes through outlet opening (18). Inlet opening (19) has a cross-section in the form of a circular arc whose size in a circumferential direction of the cylinder is greater than in a radial direction, or a multitude of inlet openings are distributed along the circular arc around the outlet opening.

EFFECT: increased efficiency and eliminated rotation of the piston in the compressor chamber about its longitudinal axis.
