Abstract
A stopping device for an engine supplied with fuel by a fuel injection pump including a change-over valve, and an actuator for actuating the change-over valve in response to an engine shutdown operation. The change-over valve is movable between a first position to which it moves at engine startup to connect a fuel tank with an inlet of a fuel supply pump driven by the engine and connect an outlet of the fuel supply pump with an inlet of the fuel injection pump, and a second position to which it moves in response to an engine shutdown operation to connect the inlet of the fuel injection pump with the inlet of the fuel supply pump and connect the outlet of the fuel supply pump with the fuel tank. The actuator includes a solenoid and a key switch operative to energize the solenoid to move the change-over valve to the first position in response to an engine startup operation, hold the change-over valve in the first position during engine operation, and de-energize the solenoid to move the change-over valve to the second position in response to an engine shutdown operation.
