ABSTRACT:
The present invention is directed to a cushioning apparatus for a pneumatic device. The cushioning apparatus generally comprises a body, wherein a piston and cylinder reside therein, wherein the piston is operable to translate along a first axis. A first port associated with a first end of the cylinder is in fluid communication with an interior portion of the cylinder through a first cushioning hole, and a second port associated with a second end of the cylinder is in fluid communication with the interior portion through a second cushioning hole. A first cushioning pin and a second cushioning pin are associated with the cylinder and the respective first cushioning hole and second cushioning hole, where the first cushioning pin is operable to enter the first cushioning hole and the second cushioning pin is operable to enter the second cushioning hole, wherein the entry of the first cushioning pin or second cushioning pin into the respective first cushioning hole or second cushioning hole generally limits a flow of gas between the interior portion of the cylinder and the respect first port or second port.
