Its structure includes a valve plate and a valve plate baffle. One end of the valve plate is fixed, and the other end can be covered with the gas supply port or separated from the gas under the change of pressure difference. When the air supply pressure is lower than the suction and exhaust pressure, the valve plate is covered on the air supply port. When the air supply pressure is higher than the suction and exhaust pressure, the valve plate is separated from the air supply port and starts to supply air into the cylinder. The valve plate baffle is used to limit Disc disengagement is excessive.

The compressor also includes a flange 3. In the conventional design of the two-stage compressor, the flange 3 is provided with an air supply port.
