FIELD: engines and pumps.
SUBSTANCE: invention is designed for compressor engineering to be used in compressors where limitation of the piston pipe deformation and overheating is required. A compressor comprises a cylinder head bolted to a cylinder assembly unit equipped with a cooling chamber and a piston pipe. The piston is mounted in the piston pipe and has a contact involved in a pipe wall integrated with the cylinder assembly unit when it slides within the pipe. The bolt and the cooling chamber are extended at least from the top contact point between the piston contact and the pipe, at least, to such low contact point between the piston contact and the pipe wall. In some versions of implementation, the cooling chamber is arranged in-between the bolt and the piston pipe. In some versions of implementation, a housing is integrated with the cylinder assembly unit.
EFFECT: deformation of the piston pipes and heating of the piston pipe walls are reduced.
