Abstract

A piston of an air compressor is actuated by a motor to move in a cylinder. The piston includes a head, an air stop sheet having a first bending section which is a boundary line of an acting area and a positioning zone of the air stop sheet, and a back surface of the acting zone backing the top of the cylinder bends relative to a plane of a top of the head at an open angle. The acting zone has a noncircular spacing groove, a neck, and a second bending section. The head includes a piston rod having a cavity, an air conduit, a column, and a spring. The air stop sheet is forced by the spring to locate in the acting zone backing the cylinder and a plane of a top of the head at an open angle.
