ABSTRACT:
A fluid dispensing tool includes parallel spaced first and second manifolds supporting therebetween an elongated actuator unit having a tubular body confining a piston connected to move a valve actuator stem projecting into a releasable coupler mounted on the second manifold. The manifolds also support therebetween a plurality of elongated valve units each having a tubular valve body defining a valve chamber and a chamber receiving a piston connected to move an elongated valve member. Each valve body has a port for receiving a corresponding fluid supply line or an evacuation line. The first manifold has separate passages connecting air control lines to the piston chambers for moving the actuator stem and each valve member axially. The second manifold has a fluid passage connecting each valve chamber to the coupler, and a handle supports the tool and a finger actuator connected to the coupler.
