Abstract: A fuel tank for a motor vehicle has means for introducing air into and venting air from the tank, and a filler pipe for filling the tank with fuel. A recirculation conduit communicates with the filler pipe. The recirculation conduit is connected to the filler pipe within the volume enclosed by the tank, approximately in the region of the outlet end of the filler pipe.

Abstract: A fuel tank for a motor vehicle has means for delivering fuel from the tank to the engine, means for the introduction of air into and the venting of air from the tank, and a filler pipe which can be closed at its intake end and which at its outlet end into the interior of the tank has at least one valve which can sealingly close at least upon a blowback of fuel thereto. At least one second valve is disposed in the filler pipe in the region of the outlet end thereof. The first valve in the filler pipe can be bridged by way of the second valve.

Abstract: A fuel tank for a motor vehicle defining at least two interconnecting with the intercommunication being by way of a tank region of smaller cross-section than the chambers, defining a saddle tank configuration. A first of the chambers contains a fuel delivery unit and a second of the chambers has a refuelling vent valve which is the only refuelling vent valve of the tank. The two chambers also communicate with each other by way of a compensating line on the basis of the principle of communicating vessels. The tank also has means for venting the compensating line. The compensating line is such that equalisation of the filling levels of the intercommunicating chambers is possible only when there is a drop in level from the second chamber to the first chamber.

Abstract: A valve assembly for use in a vehicle braking system comprises two valves having respective inlets for connection to separate wheel brakes. Each valve has a plunger carrying one part of a valve set which co-operates with a stationary part of the valve set to control communication between the inlet and outlet, and a spring urging the plunger in a direction to maintain the valve set open. Each plunger has opposed piston portions of different dimensions subjected to the pressure at the inlet of the associated valve to produce a net force tending to close the valve, and a further portion subjected to the inlet pressure of the other valve to produce an additional force which is removed upon failure of that inlet pressure of the other valve.
