Pneumatic pusher

A pneumatic pusher having a main body, a flow-guiding body, a moving body, and a delivery tube. The flow-guiding body includes a front tube with a smaller diameter and a rear tube with a larger diameter. The delivery tube is mounted on the front tube in such a way that the outer wall of the delivery tube and the inner wall of the main body define a return pressure chamber. A first gas-distributing channel extending from a first air outlet at one side of the main body leads directly to the inner side of the delivery tube. The side of the first air inlet of the main body communicates with a second gas-distributing channel. The second gas-distributing channel includes an exit located at one side of the return pressure chamber of the delivery tube. The air pressure provided through the second gas-distributing channel serves as cushioning force in pushing the delivery tube outwardly. When the moving plunger blocks the gas distributing chamber in such a way that the gas is stopped to be injected through the first gas distributing channel into the pushing chamber for bringing the delivery tube forward, the gas pressure injected through the second gas distributing channel into the return pressure chamber acts as inward return force for the delivery tube. Therefore, the reciprocating movement of the delivery tube on the front tube can be completely done by the airflow.

In a fluid pressure cylinder, first and second cylinder chambers facing respective opposite end surfaces of a piston are formed inside a cylinder tube including a supply port and a discharge port, and a first piston rod connected to one end surface side of the piston is formed to have a greater diameter than that of a second piston rod connected to another end surface side of the piston. Therefore, a second pressure-receiving area of a second pressure-receiving surface formed on the other end surface of the piston is greater than a first pressure-receiving area of a first pressure-receiving surface formed on the one end surface. Pressure fluid in the first cylinder chamber is supplied to the second cylinder chamber, whereby area difference between the first pressure-receiving area and the second pressure-receiving area causes the piston to move toward the first cylinder chamber.
