Estimating the term…
The invention relates to a valve and a fuel tank provided with a valve for a motor vehicle. Bleeder valves for integrated compensation volumes for fuel tanks are known in the prior art. One disadvantage of known valves is that if the tank is filled slowly during the refueling operation, the fuel compensation volume can fill. The invention aims to provide a valve with a compact construction. To this end a pressure valve (28) is located on the valve (1, 3) which opens if there is a predetermined excess pressure in the fuel tank (30), a refueling venting opening (38) is configured in the valve (1, 3) so that a sealing plate (5) can close the refueling venting opening. The sealing plate (5) has an operational venting opening (42), which can be closed by a displaceable closure element (15) that is displaced according to a position of a float (26) that is located on a float lever (24).
Valve for a fuel tank of a motor vehicle, having a valve chamber which is provided with a float valve, and having a connection to the atmosphere,
Valve assembly mountable in a motor vehicle fuel tank compensation volume disposed in use above a fuel level in the fuel tank, said valve assembly comprising:
Fuel tank assembly for a motor vehicle comprising at least one fuel tank chamber with an integrated compensation volume above an in use fuel level, a valve assembly in the compensation volume for each tank chamber, a vent line leading to atmosphere connected to the respective valve assemblies, and at least one rollover valve connected to the vent line outside the fuel tank, wherein each valve assembly comprises:
