Piston compressor, particularly hermetical refrigerant compressor

Abstract

The invention concerns a piston compressor (1), particularly a hermetical refrigerant compressor, with a compression chamber (2), which is bordered by a cylinder (3), a piston (4) and a valve plate arrangement (5), which has a suction valve arrangement (14, 15) and a pressure valve arrangement (16, 17). It is endeavoured to provide a piston compressor with a good efficiency. For this purpose, it is ensured that the suction valve arrangement (14, 15) opens into the compression chamber (2) in a central area of the cylinder (3) and the pressure valve arrangement (16, 17) has a plurality of pressure openings (16), which are located in an annular area surrounding the suction valve arrangement (14, 15).
