Sliding block for compressor, pump body with sliding block and compressor

The utility model relates to a sliding block for a compressor, a pump body with the sliding block and the compressor, and the sliding block for the compressor is installed in a sliding block groove of an air cylinder of the compressor and comprises a sliding block body. The sliding block body comprises a sliding block front end used for abutting against the peripheral face of a compressor rotor piston and a sliding block rear end used for being movably installed in a sliding block groove. A spring installation groove is formed in the rear end of the sliding block, the sliding block body is asymmetrically arranged relative to the horizontal center line of the sliding block body, the spring installation groove is arranged close to the bottom face of the sliding block body, and through the design, after the sliding block for the compressor is assembled, a force arm between friction resistance borne by a compression spring and friction resistance borne by the sliding block can be reduced, and therefore the slidin
