Piston pump with quick exhaust slide valve
By using a fast exhaust slide valve in the pneumatic actuated piston pump, air is directly discharged from the piston chamber into the atmosphere, solving the icing problem caused by air return and improving the performance and efficiency of the pump.

Abstract
The invention relates to a pneumatic driving piston pump and a rapid exhaust slide valve thereof, the slide valve enables air to be directly exhausted into the environment from a piston chamber of the piston pump without passing through a main distribution valve, so that the temperature is not reduced due to expansion of compressed air, water in the air is not frozen, and the service life of the air is prolonged. And the compressed air circulating pipeline is blocked, so that the pump is stopped or stuck. According to the pneumatic piston pump with the quick exhaust valve, air can pass through with low resistance, and compared with the same pneumatic motor without the quick exhaust valve, the efficiency of the piston pump is improved, and the compressed air consumption of the piston pump is reduced.
