ABSTRACT:
A valve assembly for use with a fluid-driven tool having an elongated conduit with a bore communicating with the source of fluid, and an elongated valve member received in the bore. The valve assembly has a ball received in a chamber defining a valve seat, with the chamber communicating with the source in order to drive the ball against the seat. The valve assembly has a valve pin extending through the conduit in order to actuate and move the ball away from the valve seat to permit passage of the fluid through the valve member past the seat, and a paddle for actuating the valve pin in order to open the valve.
