The invention relates to a compressor for hermetically sealed small refrigeration machines, comprising a cylinder with a cylinder housing and a piston that is guided in the piston bore of the cylinder and that compresses a working medium. The cylinder is sealed by a disc-type valve plate in the axial direction, a cylinder cover lying against or being surrounded by the plate. According to the invention, the cylinder housing comprises axial extensions facing towards the cylinder cover and located in the peripheral area of the cover. A first axial section of the axial extensions lies against the cylinder cover in the contact region between the cylinder cover and the valve plate and a second axial section surrounds the cylinder cover with a small degree of play.
