Abstract (en)
[origin: WO9840621A1] In fuel supply systems for internal combustion engines, which systems have a fuel tank, there is a risk that the fuel contained under pressure in the fuel tank might escape from the supply system after the internal combustion engine has been switched off or in case of an accident. The invention thus provides for the fuel tank (16) to be fitted with a blocking device (33) which engages a serrated actuating bar (28) by means of an electromagnetically actuated locking pin (38) after the internal combustion engine (10) has been switched off or after an accident and in this way prevents the force of a compression spring (21) from being applied against the movable wall (17) of the fuel tank (16). As a result, the pressure in the fuel line (5) is eliminated almost fully as soon as even small quantities of fuel are discharged. Said fuel supply system is suitable for internal combustion engines with air/fuel mix compression and spark ignition.
