ABSTRACT:
A combined handle and valve particularly, for piston type pneumatic tools is disclosed. The valve is positioned in a passageway between the supply and a vent to atmosphere. Another passageway starts between the valve and the supply and goes to a point of use. Thus, by throttling the exhaust, the amount of air not exhausted is directed to do useful work. The handle is extremely compact and comprises an annular port around the rear end of the cylinder.
