Abstract

A pneumatically-actuated tool for driving fasteners such as nails or staples comprises a working piston 2 movable in a cylinder 1 and controlled by an inlet valve 11 having a surface 19 acted upon by compressed air to maintain the valve closed and a larger operative surface 16 adapted to be acted upon by the air to open the valve when a trigger operated valve 12 is actuated. An air storage chamber 5 is provided which communicates with the interior of the cylinder 1 via ports 8 and with a housing 22 for a piston member 21 via a duct 25 and passages 26, 27. In operation, with the tool in the position shown, compressed air is fed via an inlet 9 into a reservoir 10 so as to act on the surface 19 of the valve 11, the space above the working piston 2 being exhausted to atmosphere via passages 13, 14. Upon actuation of the trigger 20 the valve 12 is actuated so as to allow the air to act on the surface 16 and thereby open the valve 11. Air then flows via passage 13 to act on the working piston to effect a working stroke. Towards the end of the stroke the air above the piston 2 passes through ports 8 and passages 25, 26, 27 into the housing 22 and moves the piston 21 downwardly so that via a tappet 23, it closes the valve 11. The piston 2 is then returned by air trapped in the chamber 5 and housing 22. A magnet 7 is provided for retaining the piston in its upper position.
