Refrigerant Compressor

A hermetically encapsulated refrigerant compressor having a hermetically sealed compressor housing, in whose interior a piston-cylinder unit, which compresses a refrigerant, operates, whose cylinder housing (1) is closed using a valve plate (2) having a pressure hole (10) and a suction hole (16), and a suction channel and a pressure channel are provided, via which refrigerant is suctioned via a suction valve (32) into the suction hole (16) and is compressed via a pressure valve (15) from the pressure hole (10) in the pressure channel, the suction channel being formed by a channel-shaped component (9), which is connected sealingly to the valve plate (2) along a suction contact edge (17) and which connects the suction hole (16) to a preferably provided suction noise damper (3), wherein the pressure channel is formed by an independent component (8) completely enveloping the pressure channel, which is tightly connected to the valve plate (2) along a pressure contact edge (13) formed by an end section of the component (8), preferably V-shaped sealing beads (23) or sealing projections (22) being provided in the valve plate (2) and the front face of the component (8) forming the pressure channel, which faces toward the valve plate (2), being equipped along its pressure contact edge (13) with sealing projections (22) or sealing beads (23) essentially corresponding to the V-shaped sealing beads (23) or sealing projections (22), whereas the sealing projections (22) being implemented as different in their geometrical design from the sealing beads (23) and/or having a different volume.
