  • Patent number: 11285804
    Abstract: A ventilation device for ventilating a motor vehicle tank. The ventilation device includes a filler pipe, a ventilation line, a degassing line, and a guide arc member. The ventilation line is to be fluidically connected at a first ventilation line end to the motor vehicle tank, and at a second ventilation line end to the filler pipe via a ventilation inlet. The degassing line is to be fluidically connected at a first degassing line end to the filler pipe via a degassing outlet. The guide arc member is arranged in the filler pipe to define a guide path for incoming vapor passing through the ventilation inlet into the filler pipe. The guide arc member is to facilitate flow of the incoming vapor between an inner wall of the filler pipe and the guide arc member along a periphery of the filler pipe along a periphery of the filler pipe such that a gaseous component of the incoming vapor escapes through the degassing outlet and a liquid component of the incoming vapor flows off through the filler pipe.

  • Publication number: 20200360839
    Abstract: A venting device for venting a motor vehicle tank that includes a filling pipe, a venting line, a degassing line, and a connection nipple. The venting line is for fluidic connection at a first venting line end to the motor vehicle tank, and at a second venting line end opposite the first venting line end to the filling pipe via a venting inlet. The degassing line is for fluidic connection at a first degassing line end to the filling pipe via a degassing outlet, and at a second degassing line end opposite the first degassing line end to a liquid separator. The connection nipple is arranged on the filling pipe upon which the venting inlet and the degassing outlet are constructed.
