  • Skirted dashpot piston
    Patent number: 3960250
    Abstract: An improved decelerating mechanism of the dashpot type in which the piston normally leaves the cylinder on each operating cycle and has a sealing ring cantilevered in the direction of piston travel having a deep undercut whereby air pressure of the air compressed in front of the piston inside the cylinder biases the cantilevered sealing ring against the wall of the cylinder to accomplish effective sealing of the piston against uncontrolled air leakage. A projection on the front of the piston seals the air exit from the compression chamber during the last portion of piston travel in order to provide a final cushion for the moving dashpot piston.
