摘要

Anti-theft and/or safety device. The fuel supply circuit 14 is provided with a plug cock 1; downstream there is a solenoid valve 12; this solenoid valve 12 is mounted on the supply circuit 17; the said solenoid valve 12 is mounted on an electrical excitation circuit connected to a pressure switch 13 which closes a relay 18; this circuit is connected to earth and to a positive pole 15 of the contact key 16 in the parked or road-going position; a by-pass circuit 19 on which a time delay relay 20 is mounted, is mounted on this excitation circuit. The invention applies particularly to motor vehicles.
