Abstract
An air-seal structure for pneumatic nailers includes a valve member movably engaged with the end cap of the nailer and a plurality of paths defined radially through a skirt portion of the valve member. The paths are in communication with air release passage defined in the end cap. A seal is mounted to the skirt portion of the valve member and closes the paths. The seal contacts an end of the cylinder when the trigger is not squeezed. The seal is sucked due to the difference of pressure so that it will not be loosened during movement of the valve member. A cushion member is connected to a disk member on the inside of the end cap so as to absorb shocks when the piston returns back to the ready position.
