PCT No. PCT/GB96/01405 Sec. 371 Date Mar. 3, 1998 Sec. 102(e) Date Mar. 3, 1998 PCT Filed Jun. 13, 1996 PCT Pub. No. WO96/41981 PCT Pub. Date Dec. 27, 1996A fluid flow control valve suitable for fitting to the fuel line (16, 18) of an internal combustion engine has a valve member (12) and a spring (14) urging the valve member (12) to a closed position where the valve member seals against a valve seat (13). A key-actuated setting mechanism (20, 21) allows the valve member (12) to be moved away from its closed position to an open position and a latch (31, 32) then holds the valve member in that open position. An electrically operated release (33) moves the latch (31) to free the valve member and permits the valve to close under the action of the spring (14). When fitted to a vehicle, energy may be provided to the release (33) automatically whenever the vehicle is left unattended so as to immobilise the vehicle.
