ABSTRACT:
A hydraulic gun includes a gun body within which a trigger operated valve and a second, pressure operated valve are supplied with water under pressure from a pump. The trigger operated valve is normally open and returns water at a comparatively low pressure to a water reservoir, but when the trigger operated valve is closed, the water pressure opens the second valve, through which water is delivered to a nozzle.
