Claims
- 1. A fastener driving device comprising:
a housing containing a chamber for storing compressed air a cylinder structure disposed within said housing; a piston movably disposed within said cylinder; a driver connected to said piston; a main valve cooperable with said cylinder structure and movable between an open position and a closed position, wherein said open position allows air to move said piston through a drive stroke through said cylinder; and a trigger valve operable between a first position wherein said trigger valve communicates air pressure from said chamber to said main valve through a signal passageway so as to retain said main valve in a closed position, and a second position wherein said passageway is exhausted to atmosphere to permit said main valve to open, and wherein said cylinder and said signal passageway comprise an integrally molded structure.
- 2. A fastener driving device as recited in claim 1, wherein said cylinder and said signal passageway form a single structure molded from a plastic.
- 3. A fastener driving device comprising:
a housing containing a chamber for storing compressed air; a cylinder structure disposed within said housing; a piston movably disposed within said cylinder; a driver connected to said piston; a main valve disposed towards the top of said cylinder structure and movable between an open position and a closed position, wherein said open position allows air to move said piston through a drive stroke; and a trigger valve operable between a first position wherein said trigger valve establishes a first pressure signal at said main valve through a signal passageway so as to retain said main valve in a closed position, and a second position wherein said trigger valve establishes a second pressure signal at said main valve through said passageway to permit said main valve to open, and wherein said cylinder and said signal passageway comprise an integrally molded structure.
- 4. A fastener driving device as recited in claim 3,
wherein said cylinder and said signal passageway form a single structure molded from a plastic.
- 5. An integrally molded structure for use in a fastener driving device comprising:
a cylindrical portion having an inner cylindrical surface adapted to cooperate with a piston, said cylindrical portion having a longitudinal axis, a passage portion disposed radially outwardly from said cylindrical surface and having an upper portion adapted to communicate with an upper portion of said cylindrical portion and a lower portion adapted to communicate with a trigger valve, said passage portion being integrally molded with said cylindrical portion.
- 6. A method of forming a cylindrical structure and a signal passageway for a fastener driving device comprising:
providing a mold structure that defines both said cylindrical structure and said signal passageway; introducing molten material to said mold structure; and forming both said cylindrical structure and said signal passageway in a molding operation.
- 7. The method of forming a cylindrical structure and a signal passageway as recited in claim 6, wherein said material comprises a polymeric material.
- 8. The method of forming a cylindrical structure and a signal passageway as recited in claim 6, wherein said material comprises a metal.
- 9. A fastener driving device comprising:
a housing containing a chamber for storing compressed air; a cylinder structure disposed within said housing; a piston movably disposed within said cylinder; a driver connected to said piston; a main valve cooperable with said cylinder structure and movable between an open position and a closed position, wherein said open position allows air pressure to communicate with and drive said piston; a trigger valve operable between a first position and a second position, wherein an air pressure signal passage communicates air pressure between said trigger valve and said main valve, wherein when said trigger valve is in said first position said main valve is closed and when said trigger valve is in said second position said main valve is open, wherein said cylinder structure and said signal passage are integrally formed, and a peripheral seal structure surrounding an upper portion of said cylinder structure and an upper portion of said signal passage facilitate air pressure communication of said upper portions.
