Abstract
An automatic engine shut down device is operable in a system of the type including a pump having a suction inlet and a pressure discharge for discharging a liquid at a operational pressure, an engine for driving the pump, the engine being operable by an engine operating fluid, the engine including a control member for controlling the supply of engine operating fluid to the engine, the control member being movable between a first open position allowing operation of the engine and a second closed position shutting down operation of the engine. The automatic shut down device is operable, upon the removal or substantial reduction of suction at the inlet of the pump, to automatically terminate operation of the engine and thereby of the pump.
