An operating fluid container for a motor vehicle for accommodating an operating fluid. The operating fluid container has a compensation container that is at least indirectly fluidically connected to the atmosphere (ATM). The operating fluid container has the following features: the compensation container is situated within the operating fluid container in such a way that an outer surface of a compensation container upper shell is situated opposite from an inner surface of an operating fluid container upper shell; in the event of positive pressure in the operating fluid container relative to the atmosphere, a compensation container volume decreases; and in the event of negative pressure in the operating fluid container relative to the atmosphere, the compensation container volume increases. The operating fluid container is characterized in that the compensation container upper shell opposite from the operating fluid container upper shell has a shape, at least in sections, that is complementary to the operating fluid container upper shell.

A valve module for an operating fluid container system. The valve module has a housing which has a first connection for fluidically connecting to an operating fluid container interior, a second connection for fluidically connecting to a filler tube, and a third connection for at least indirectly fluidically connecting to the atmosphere. The valve module comprises the following features: the first connection is connected to the second connection and the third connection within the housing in a fluidic manner in each case; the second connection is connected to the third connection within the housing in a fluidic manner; and the first connection, the second connection, and the third connection can each be adjusted independently of one another between an open position, in which fluid communication through the respective connection is allowed, and a closed position, in which fluid communication through the respective connection is prevented.

Valve module

The invention relates to a liquid/vapor separator () for a fuel tank for motor vehicles, comprising a housing () having a droplet collecting space () for fuel in vapor form. The housing () is provided with a connection cross section () which, in the installed position, opens into a space surrounded by a filler pipe of the motor vehicle. The liquid/vapor separator () comprises at least one first connection () for a refueling vent line of the fuel tank, said connection opening into the droplet collecting space (), a second connection for a service vent line of the fuel tank, and a third connection () for a vent line leading to a fuel vapor filter. The liquid/vapor separator () according to the invention furthermore comprises at least one valve, which closes at least a service vent path () from the second connection to the fuel vapor filter during refueling of the motor vehicle, wherein the service vent path () is routed as a channel bypassing the droplet collecting space () into the connection cross section () of the housing ().
