Abstract
A piston of an air compressor contains at least one fixing bolt configured to fix a plane of a top of a head of the piston to at least one air stop sheet. A respective one of the at least one air stop sheet includes at least one bending section and at least one acting zone surrounding the at least one bending section and configured to cover at least one air orifice. A back surface of the at least one acting zone of the respective one air stop sheet moves away from the plane of the top of the head at an open angle θ, thus producing an air flowing space. A pressure of a cylinder balances with atmosphere, and the piston is not stopped by a back-pressure resistance to move smoothly in upward and downward moving strokes after the air stop sheet moves again.
