ことを特徴とする空気圧縮機。 In an air compressor, a piston ring is fitted into a piston ring groove formed on the outer periphery of the piston so as to be movable in the radial direction and to be urged outward in the radial direction so as to come into close contact with the inner surface of the cylinder. A communication hole communicating with the compression chamber and the crank chamber is formed in the communication hole, and the communication hole is normally closed, and when the piston ring is worn out by a predetermined amount or more, the displacement caused by the wear of the piston ring is prevented. An air compressor characterized by being provided with an opening/closing mechanism that opens a communication hole.
