ABSTRACT:
A fastener driving tool for driving remotely located fasteners through preformed openings in a structure. The tool (10) comprises a housing (12) having a pneumatic-hydraulic intensifier (14) mounted thereon and a remotely located second hydraulic cylinder assembly (20) attached to the housing (12) by means of an extension tube (110). Pressurized air is provided to the tool (10) through a cartridge regulator (36) that is controlled by a trigger assembly (41). A pneumatic piston (72), connected to a first hydraulic piston (76) by a piston rod (80), moves from a first position located away from a nose portion (66) to a second position located toward a nose portion (66). The pressurizing valve (56) admits air to the pneumatic piston (72) to cause the first hydraulic piston (76) to move to the second position, thereby pressurizing hydraulic fluid (92) and causing the second hydraulic piston (102) to extend from the second cylinder housing (104). A rotating union (22) connects the extension tube (110) to the housing (12) and permits rotation of the second hydraulic cylinder assembly (20) about the longitudinal axis of the pneumatic-hydraulic intensifier (14). A fluid reservoir (68) supplies fluid to the first hydraulic cylinder assembly (18) and captures entrapped air bubbles within the fluid (92).
