An assembly for applying a fluid on a workpiece from a fluid storage supply includes a fluid supply for supplying a fluid. An air supply supplies compressed air. An injector is connected to the fluid supply for receiving fluid from the fluid supply and for receiving air from the air supply and injecting the fluid to the workpiece in response to the air being supplied thereto. A solenoid interconnects the air supply and the injector for controlling the air supply to the injector to actuate the injector. An accumulator receives exhausted air from the injector in response to the actuation of the injector and returns air from the accumulator after the actuation of the injector is completed to allow the injector to be actuated again.
