ABSTRACT:
A pneumatic system consisting of an air pump, air-passage switching means, operating components and air pipes connecting those together. This pneumatic system features improvements in a pressure smoothing means for smoothing a surge pressure discharged from an air pump in the pneumatic system, which pressure smoothing means is built in the pneumatic system between the air pump and the air-passage switching means. The pressure smoothing means includes an air chamber having an air inlet and an air outlet, and means for increasing and decreasing the volume of the air passage defined between the aforesaid air inlet and outlet, commensurate to the surging discharge pressure from the air pump, i.e., in response to the surge pressure of the air being admitted in the air chamber. This pressure smoothing means is provided with a pressure receiving plate which is displaced under the air pressure being introduced into the air chamber, whereby the volume of the air passage defined within the air chamber may be adjusted.
