Abstract

The invention discloses a round cylinder head assembly of a refrigerating compressor, used for the technical field of compressors. The round cylinder head assembly comprises a cylinder seat and a cylinder head assembly, wherein a cylinder body is arranged on the cylinder seat, a cylinder hole is arranged in the cylinder body, the far end of the cylinder body is provided with a round cylinder head,a mounting hole is arranged in the cylinder head, the cylinder head assembly comprises an air inlet valve, an exhaust valve, a cylinder cover and a fastening component which can be connected with thecylinder head so as to limit the air inlet valve, the exhaust valve and the cylinder cover in the mounting hole, and an air intake channel communicating with the air inlet valve and an exhaust channel communicating with the exhaust valve are arranged on the cylinder cover. By designing the round cylinder head component, the design is compact, occupied space is small, and an upper shell can be correspondingly reduced; at the same time, the weight of the cylinder head component is light, the gravity center of a machine core is closer to a geometric center, and the work of the compressor is morestable; by adopting thread connection, the fastening stress of the cylinder head is uniform, and the working environment of a piston is better; and besides, as the number of parts is small, materialcost is saved.

Description

technical field [0001] The invention is used in the technical field of compressors, and in particular relates to a circular cylinder head assembly of a refrigeration compressor. Background technique [0002] The cylinder head parts of refrigeration compressors for refrigerators include cylinder head, cylinder head gasket, valve plate, exhaust valve plate, suction valve plate, valve plate gasket and other parts, which are generally fastened by cylinder head screws It is fixed on the plate surface of the cylinder hole of the cylinder block. In order to ensure that the cylinder block plate is evenly stressed and the deformation of the plate is small when the screws are fastened, four cylinder head screws are usually used for fastening, so the plate surface of the cylinder block is usually designed as a quadrangle close to a square. Four cylinder head screws are distributed on the four corners of the quadrilateral cylinder block surface, leaving enough circular space for the cy...
