Abstract

An air compressor contains a piston actuated by a motor to move in a cylinder. The piston includes an air stop sheet mounted on a top support plate thereof. The air stop sheet includes a bending section having a positioning zone and an acting zone located opposite to the positioning zone and configured to cover an air channel of the piston. The bending section is a boundary axis of the acting area and the positioning zone of the air stop sheet so that a top of the air stop sheet facing the cylinder forms an obtuse angle less than 180 degrees, and a back surface of the acting zone of the air stop sheet backing a top of the cylinder turns on relative to a plane of a top of the top support plate at an open angle θ, thus producing an air flowing space.
