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.

Methods and systems are provided for aging a new plastic fuel tank in a vehicle. In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

Provided are a filler tube and a filler neck including the filler tube that may reliably prevent false injection of fuel even though structures thereof for suppressing the false injection of the fuel are simplified. A filler tube defining a path through which fuel from an injection nozzle is supplied to a fuel tank is provided. The filler tube includes: a main body having a hollow defined therein, into which the injection nozzle is inserted; a first rotating part disposed to penetrate one side wall of the main body and axially connected to the main body to be axially rotatable outwardly of the main body; and a second rotating part disposed to penetrate the other side wall of the main body to face away from the first rotating part and axially connected to the main body to be axially rotatable outwardly of the main body.

The fuel supply device comprises a filler neck provided to include a fuel supply port which a fueling gun is inserted in and configured to form part of a fuel passage from the fuel supply port to a fuel tank, a fuel vapor pipe connected with the fuel tank and with a fuel vapor port and configured to supply a fuel vapor in the fuel tank to an internal passage of the filler neck main body, and a buffer member at least partly placed between a filler neck main body and the fuel vapor port in a neighborhood of a branch portion where the fuel vapor port is branched off from the filler neck main body. The filler neck comprises the filler neck main body including the internal passage and the fuel vapor port branched off from the filler neck main body.

A filling head for filling a tank with a liquid, the filling head delimiting a conduit for filling the tank which extends axially along a filling axis from an upstream section which is adapted to receive a filling nozzle, up to a downstream section which is designed to be connected on the tank to fill, and a degassing circuit including an inlet which is adapted to be connected on the tank and an outlet in communication with the outside, the filling head being characterized in that it delimits a suction window which connects the downstream section of the filling conduit on the degassing circuit, so as to promote the suction of the gases via the degassing circuit, during the filling of the tank.

A closed tank system includes: a fuel tank; a canister adapted to adsorb evaporative fuel generated in the fuel tank; a fill-up limiting valve provided inside the fuel tank so as to be communicated with the evaporative fuel discharge passage and adapted to operate to close the evaporative fuel discharge passage when a fuel level reaches a predetermined full tank liquid level; a shut-off valve adapted to operate to open or close the evaporative fuel discharge passage; a fuel remaining amount sensor adapted to detect a remaining amount of fuel; and a hardware processor that causes a control section to carry out control for allowing the shut-off valve to be opened or closed. The hardware processor causes the control section to inhibit the control for allowing the shut-off valve to be opened when an engine is in operation and the detected remaining amount of fuel exceeds a predetermined threshold.

A combined force- and temperature-sensing array includes an array of drive plates, an array of sense plates corresponding the drive plates, and a layer of dielectric material separating the drive and sense plates. A diode with a forward junction voltage is connected between at least one of the drive plates and at least one of the sense plates. A multiplexer is operative to select between an electrical pulse or an electrical current for delivery to the at least one drive plate. Circuitry is provided for sensing an applied force resulting from a change in capacitance between the at least one drive plate and the at least one sense plate when the electrical pulse is delivered, and for sensing a temperature resulting from a change in the forward junction voltage of the diode when the current is delivered. The sensor array may be provided as a shoe insert for diabetics with neuropathy.

A fuel supply device includes a valve body and a filter unit accommodating an air filter and a valve cap are attached to a tubular portion provided on a side surface of an inlet pipe. When a fuel tank has a negative pressure, the valve body opens and the negative pressure is eliminated by clean atmospheric air introduction. A projection portion is provided on the filter unit side of the valve body. Accordingly, attachment of the valve body into the tubular portion and attachment of the tubular portion and the filter unit are reliably performed, the reliability of valve body opening and closing is improved, and attachment workability is improved.

A filler neck for use with an automotive fluid container having a body that includes an opening in communication with a reservoir and a fluid passageway for allowing fluid to flow through the body into the container. The reservoir and the fluid passageway are configured to regulate fluid flow through the body. The reservoir has a fill limit section. The body further includes an air passageway, an air channel and an exhaust port for allowing displaced air from the container to flow through the body. The air passageway, the air channel and the exhaust port are integrally formed with the body. The exhaust port is positioned above the fill limit section to maximize air exhaust and minimize fluid leakage from the body.

Methods and systems are provided for nozzle guides for vehicle refueling adapters. In one example, a nozzle guide includes a plurality of protrusions adapted to center a fuel nozzle within the nozzle guide and to reduce a likelihood of over-insertion of the fuel nozzle into the nozzle guide. The nozzle guide may include features such as a rear guard and upper wall adapted to reduce ingression of liquid fuel with fuel vapor flowing from the fuel tank.
