The air suction valve plate, the valve plate and the exhaust valve plate are all provided with rotary limitingprotrusions matched with the rotary limiting groove. The compressor comprises the cylinder end assembly. The cylinder end component adopts a circular design, and the cylinder end component is installed on the cylinder seat through the fasteners, so that the overall size of the cylinder end component is saved, the material is saved, the weight is reduced, the cost is reduced, and the vibration noise generated when the compressor works is reduced; and meanwhile, the cylinder end component adopts the circular design, and the rotary limiting groove is matched with the rotary limiting protrusionsof the cylinder end component, so that the cylinder end component is prevented from rotationally moving, and the function of accurate positioning is played.
