Patent ID: 7404414

Claim:
A dispensing tool assembly adapted to be releasably connected to a fluid supply line for charging a fluid system, said tool assembly comprising a first manifold and a second manifold arranged in parallel spaced relation, said second manifold having an outlet adapted to be connected to a fluid receiving system, at least one elongated valve unit extending between said manifolds, said valve unit including a valve body defining a valve chamber receiving an axially movable elongated valve member, said valve body having a valve seat adjacent said second manifold and said valve member having a closure portion adjacent said valve seat, a piston chamber within said valve body adjacent said first manifold and receiving a piston connected to move said valve member closure portion axially between open and closed positions, a fluid supply passage within said valve body and connected to said valve chamber, said first manifold having an air control passage connected to said piston chamber and adapted to be connected to a pressurized air control line, said second manifold defining a passage connecting said valve chamber to said outlet when said valve member is in said open position, and said manifolds being connected together with fluid-tight seals between said manifolds and said valve body.
