  • Fastener driving tool having pressurized power source
    Patent number: 6786379
    Abstract: A fastener driving tool is disclosed having a self contained pre-pressurized pneumatic power source. Operator actuation of a trigger mechanism causes a pressurized medium supplied by the self contained pre-pressurized power source to flow through a valve and to propel a piston connected to a driver blade towards a nosepiece assembly end of the tool. The flow of the pressurized medium through the valve further recoils a spring-biased activating bolt which resets the trigger mechanism.
