An actuator housing (20) for use on a pneumatic nailer (10), the actuator housing comprising a casing (22) defining a cartridge insertion opening (24), and a selectively activated actuator cartridge (50) which is inserted in the casing through the cartridge insertion opening. The actuator housing further comprises a releasable second fastening means (30, 69) which allows releasable extraction of the actuator cartridge from the casing. The actuator cartridge comprises an actuator head (54) for sealing engagement with the cartridge insertion opening of the casing and extending outwardly of the casing. The actuator cartridge also comprises a piston assembly (58) received within the casing, the piston assembly comprising a cylinder (100) defining a cylinder chamber (101) therein and a plunger (120) movably mounted within the cylinder chamber. The actuator cartridge further comprises first fastening means (71, 104) to fasten the actuator head to the cylinder of the piston assembly. Upon selective activation of the actuator cartridge, the plunger is actuated along the cylinder chamber.
An actuator housing for use on a pneumatic nailer, the actuator housing comprising a casing, at least partially hollow, defining a cartridge insertion opening. The actuator housing also comprises a selectively activated actuator cartridge which can be inserted in the casing through the cartridge insertion opening. The actuator cartridge in turn comprises an actuator head for sealing engagement with the cartridge insertion opening of the casing, the actuator head extending at least partially outwardly of the casing. The actuator cartridge further comprises a piston assembly received at least partially within the casing, the piston assembly comprising a cylinder defining a cylinder chamber therein and a plunger movably mounted within the cylinder chamber. First fastening means fasten the actuator head to the cylinder of the piston assembly. The actuator housing also comprises releasable second fastening means, allowing releasable fastening of the actuator cartridge to the casing. Upon selective activation of the actuator cartridge, the plunger is actuated along the cylinder chamber. Moreover, to extract the actuator cartridge from the casing, the second fastening means can be released to disconnect the actuator cartridge from the casing.
