The mechanical breather valve includes a valve body, on which is installed one-way air inlet and outlet components. A tank, for environmental protection, is fitted with the breather valve and closed so that no volatile gas will be exhausted, when the pressure within is balanced with the outside. When the pressure within is negative, the one-way air inlet hole will draw air from outside to keep the balance of pressure. When the pressure within is increased, one-way air outlet hole will exhaust the additional air. When the tank is tilted or placed upside down, the breather valve can prevent the oil from flowing out of the tank for safe usage.

There is provided a closing device for a filler port. This closing device for the filler port comprises a fuel passage forming portion configured to include a first engagement element; a first open-close mechanism configured to include a first cover that is opened toward an upstream side; and a second open-close mechanism configured to open and close a second opening and include a second cover that is opened toward the upstream side. The first open-close mechanism further comprises a disengagement portion located on the upstream side of a second engagement element when the second engagement element is engaged with the first engagement element, and configured to disengage the second engagement element from the first engagement element when receiving a force in a closing direction from the second cover.

A vehicle seat that provides rigidity of the seat while enabling weight reduction of the seat is provided. The vehicle seat has upper ribs projecting from a top surface and lower ribs projecting from a bottom surface in a seating region of a bottom plate. Also provided in the seating region are a center protrusion portion formed at a center portion and an annular protrusion portion formed outside the center protrusion portion to have a space therebetween. The upper ribs are formed at parts different from parts at which the center protrusion portion and the annular protrusion portion are formed, while the lower ribs are formed at the parts at which the center protrusion portion and the annular protrusion portion are formed. The upper ribs and the lower ribs are arranged alternately, while extending radially from the center protrusion portion toward the annular protrusion portion to form a honeycomb shape.

The horizontal shaft fuel tank cap with charcoal canister includes a fuel tank inner cap and fuel tank outer cap. A hollow room with an upper opening is disposed in the center of the fuel tank inner cap. The fuel tank outer cap is disposed above the fuel tank inner cap. The ventilating pipe is disposed in the hollow room and divides the hollow room into filling room and containing room. The first air outlet leading the fuel vapor to the containing room is disposed on the bottom of the containing room. The second air outlets are disposed in the center of the ventilating pipe. The fuel-absorption substrate is disposed in the filling room. The residuary fuel is drained into the fuel tank under negative pressure of the fuel tank. The filtering performance of charcoal powder can be enhanced since it is exempted from long-time fuel soaking.

A filler neck assembly including a main channel for supplying a liquid into a tank and an auxiliary channel for evacuating gas from the tank. The main channel includes a tubular main body including a first end receiving a filler spout and a second end discharging the liquid into the tank. The auxiliary channel includes a first section and a second section, the first section being a channel integrally molded with the tubular main body, and the second section being formed by a feature on an exterior of the main body cooperating with a separately formed part.

An integrated fill system is provided for a vehicle. The integrated fill system can include a receptacle, a cap that mates with the receptacle, and a fill line that is in fluid communication between the receptacle and a container. The integrated fill system can further include a valve between an opening on an end of the container and an end of the fill line to allow one-way fluid communication for entry of compressed material into the container. The integrated fill system can further include a draw line on an opposite end of the container to maintain separate lines for filling and drawing compressed material into/from the container.

A fully-integrated flow-control module is designed to fit within a filler neck of a DEF tank that conforms to ISO (International Organization for Standardization) Standard 22241-4:2009(E). The flow-control module includes a breather cap that locks the flow-control module within the mouth of the ISO filler neck. A spring-biased valve piston, which is controlled by a bleed path within a bleed and float body, opens and closes to control fluid flow into the DEF tank. A fluid level float is mounted on a control rod. The control rod and a bleed valve poppet are rigidly secured to a connector beam. When fluid levels in the tank raise the float, the bleed valve poppet seals a bleed circuit escape port, thereby enabling the valve piston to close, increase fluid pressure at the nozzle, and cause the nozzle to shut off.

A tank closure that includes a first tank closure member, a second tank closure member, and a bias member having a spring force to brace the second tank closure against the first tank closure member. The first tank closure member has a first stop member, while the second tank closure member has a second stop member. The second tank closure member is flexibly mounted in an axial direction relative to the first tank closure member, the second tank closure member. The second stop member, in a closed position of the tank closure, forms a mechanical stop relative to the first stop member to prevent axial movement of the second tank closure member relative to the first tank closure member against the spring force of the bias member.

A plug monitoring device configured to monitor a plug to be received by an aperture of a pipe is provided. The plug monitoring device may include: a sensor having an output, wherein the sensor is configured to produce at the output a first signal when a plug is tightly installed in the aperture and a second signal at the output when the plug is not tightly installed in the aperture; and circuitry, comprising a transmitter, coupled to the output of the sensor, wherein the circuitry is configured to transmit a signal comprising status information selectively based on a signal at the output of the sensor.

An automatic opening and closing device for a fuel inlet of a vehicle may include a cap cover mounted at the fuel inlet of the vehicle, a fuel cap pivotably mounted at the cap cover and configured to selectively open or close the fuel inlet by being pivoted inside the fuel inlet, and a fuel cap operating mechanism mounted in the fuel inlet and configured, when the fuel door is closed, to pivot the fuel cap by being pressed by the fuel door to close the fuel inlet, and, when the fuel door is opened, pivot the fuel cap to open the fuel inlet according to release of pressing by the fuel door.
