Abstract

A fuel container, in particular for motor vehicles, comprising an aereation and de-aereation device for balancing the internal gas pressure during filling of the container with fuel and during consumption of the fuel during the operation of a working machine powered by the fuel. The aereation and de-aereation device has a separator device for separating liquid fuel from an aereation and de-aereation line. In order to permit the separator device to be emptied, if a fuel pump, which serves this purpose during normal operation, is not in operation, the separator device comprises a housing and a pipe nozzle which is connected to the housing either directly or via a pipeline and in which pressure fluctuations occur as a result of incoming and outgoing fuel, said fluctuations acting as a pump for emptying the separator device.
