Abstract
A sealing assembly for an inlet valve of a power nailer includes a fixed frame and a movable member which has a tubular portion movably inserted through the central hole of the fixed frame and is biased by a spring. The movable member is connected to the cylinder so as to push the piston of the cylinder. The fixed frame has a flange with a tapered distal edge so that a seal is mounted to the flange and the seal has a tongue portion rested on the tapered distal edge. The tongue portion movably contacts the tubular portion. The movable member has a tapered distal edge on which a tongue portion of another seal is rested and movably contacts a flange of the fixed frame.
