ABSTRACT:
A cylinder inlet valve for a power stapler includes a head member connected to the rear end of the barrel of the stapler and a cap movably connected between the head member and the cylinder between which a seal is connected which has a flexible portion so that when the cap is moved, the seal is removed from the cylinder and the flexible portion is extended and the sealed situation between the cap and the head member is maintained. Another seal is mounted to the neck portion of the cap with its tongue portion and connected between the neck portion and the short flange of the head member, so that the friction between the neck portion of the cap and the tongue portion is small when the cap is moved.
