Abstract
A piston compressor, particularly a refrigerant compressor includes a compression chamber in a compressor block, the compression chamber being delimited by a cylinder head (10), the cylinder head (10) comprising at least one valve plate arrangement with at least one suction valve (23, 24) and at least one pressure valve (21, 22), as well as a valve cover (12). To achieve low manufacturing costs, though maintaining a good efficiency, the valve plate arrangement (16) is formed by a carrier plate (17) that comprises the suction valve (23, 24, 26, 27) and the pressure valve (18, 19, 21, 22) and is connected by at least one gas-tight connection seam (28, 31) to the valve cover (12), the connection seam (28, 31) separating a suction area (32) and a pressure area (29, 30) from one another and sealing at least the pressure area (29, 30) towards the outside.
