A method for controlling a filling process of a motor vehicle tank comprising the following steps: determine a geographical location of the motor vehicle tank; determining, by means of a tank control device, whether the geographical location of the motor vehicle tank is within a predetermined geographical area; and determining a shut-off filling volume dependent on the geographical location of the motor vehicle tank, if the geographical location of the motor vehicle tank is within the predetermined geographical area.

A system for controlling shut-off of a fuel pump nozzle in a fuel tank includes: a fuel evaporation gas blocking unit configured to separate an outer space of a fuel injection part of the fuel pump nozzle inserted inside the filler pipe into a first space into which external air is introduced and a second space into which fuel evaporation gas that is discharged from the fuel tank is introduced and to block the evaporation gas from being introduced into the first space; an external air suction jet pump mounted in the fuel tank and configured to suck external air thereinto and discharge the external air into the fuel tank, by receiving a portion of fuel transmitted from the fuel pump in the fuel tank as a working fluid; and a jet pump connection hose configured to connect the first space and the external air suction jet pump.

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.

A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The poppet valve assembly has a poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes a poppet valve fluidly coupled to the first LVD. The second cam has a profile that actuates the pump.

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.

A module (49, 149, 249) for use in a vehicle fuel system, said module comprising a housing (7) having a first port (9), a second port (41) and a passage (57) between the first port and the second port; a closure body (11) that is moveably arranged in said housing; wherein said closure body is configured for closing the passage between the first port and the second port in a first position of the closure body and for allowing access to the passage in a second position of the closure body; and a pump (13) that is integrated in said housing (7), wherein said pump (13) communicates with the first port (9) and is configured for pumping fluid into or out of the first port (9) while the closure body (11) is in the first position, characterized in that the module (49, 149) further comprises a motor (15) and a closure body actuator (67) configured for positioning the closure body (11, 111) in at least the first position and the second position, wherein said closure body actuator is driven by said motor (15), and said motor is configured for driving the pump (13) while the closure body is in the first position.

Example methods and apparatus to ensure grounding between vehicles during a vehicle-to-vehicle refueling operation are described herein. An example vehicle described herein is to receive fuel from a refueling vehicle via a vehicle-to-vehicle refueling operation. The example vehicle includes a fuel tank having a vent passageway, a valve coupled to the vent passageway, and a controller to close the valve if the vehicle and the refueling vehicle are not electrically coupled during the vehicle-to-vehicle refueling operation.

A fuel shutoff valve includes a valve, a float, and an auxiliary member. The valve is configured to open or close an air passage of a fuel tank. The float floats on fuel and moves in a valve closing direction to close the valve, or in a valve opening direction opposite to the valve closing direction to open the valve. The auxiliary member has a predetermined weight, and abuts on the float to apply a weight on the float in the valve opening direction, or separating from the float not to apply the weight on the float in the valve closing direction.

A vent shut-off assembly configured to manage vapor recirculation venting during a refueling event on a fuel tank configured to deliver fuel to an internal combustion engine includes a main housing and an actuator assembly. The main housing selectively vents to a carbon canister. The actuator assembly is at least partially housed in the main housing. The actuator assembly comprises a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that actuates a first valve that selectively opens a first port fluidly connected to a first vent in the fuel tank. The second cam has a profile that actuates a second valve that selectively opens a second port fluidly connected to a recirculation line that routes vapor back to a filler neck of the fuel tank.

In a valve device for a fuel tank, a fuel liquid level of filling-up fuel feed and an allowable fuel amount of additional fuel feed can be easily and appropriately changed by replacing only a part of components forming the valve device. A first valve chamber has a structure of positioning an open end below a support portion of a first float having a passage portion for a fluid. A second valve chamber includes a support portion of a second float having a passage portion for the fluid. The first valve chamber and the second valve chamber are formed by fitting a lower-portion including the support portion and the open end of the first float and the support portion of the second float relative to an upper-portion including a first valve opening and a second valve opening.
