ABSTRACT:
A high pressure fluid delivery system is disclosed in which two or more dump guns, each having a high pressure nozzle outlet and a low pressure dump outlet, may be connected to and operated from a single high pressure pump. Pressure responsive flow control apparatus is provided in the flow line between each gun and the pump to maintain a substantially constant load on the pump even though the dump guns are randomly operated. A motor control apparatus is also provided for controlling the speed of an engine driving the pump and this apparatus is connected to the pressure responsive control apparatus through a shuttle valve so that the engine idles when all of the guns are dumping, but automatically runs at a faster speed when one or more of the dump guns is actuated to provide a high pressure fluid blast.
