A solenoid operated valve 1 biassed to a closed position in which it will cut off the supply of fuel to the engine will be opened when a circuit 2 is completed. For the solenoid 6 to be energised a switch 5 and a switch 3 in circuit 2 must be closed. Switch 3 is lock-operated and may be in a concealed position in the vehicle driven by the engine. The switch 5 may be the ignition switch or a light or radio operated switch. The lockable switch 3 may be operated by a key 15 or an electric signal. <IMAGE> |
