  • Patent number: 11358732
    Abstract: A fuel tank with a venting system includes a flap for closing and opening a vent made in the tank. The flap is coupled to a float. The flap includes a valve coupled to a second float mounted in a hinged manner in the tank so that the valve adopts a closed position, being pushed by the second float when the level of fuel in the tank reaches a certain threshold, and an open venting position in order to prevent overpressure within the tank, being driven by the second float when the level of fuel is below the threshold and the force exerted by the internal pressure on the valve is less than the sum of the forces exerted on the valve by the atmospheric pressure and by the weight of the second float.

  • Patent number: 11261985
    Abstract: An improved gas vent having a body defining a float chamber. A float is positioned within the float chamber. The float chamber defines a passageway for gas to flow from an first port to an outflow port. A float is positioned within the float chamber. The float is configured to move toward a closed position as the fluid level within the float chamber increases. As the fluid level increases the float raises and seals against an interior of the gas vent, preventing further fluid flow through the vent. A shield is positioned between the float and the first port. The shield is configured to deflect gas flow around the shield and float to prevent the float from raising prematurely in response to high velocity gas flow on the float.

  • Patent number: 10293953
    Abstract: The invention relates to a tank for receiving fuel, said tank comprising a venting system comprising a flap for closing an opening made in the tank, said flap being subjected to a float and mounted in a hinged manner in the tank so as to adopt a closed position, pushed by the float when the level of fuel in the tank reaches a certain threshold, and an open, venting position, driven by the float when the level of fuel is below said threshold. According to the invention, the flap comprises a valve controlled by means that can open the valve when the flap is in a closed position and the level of fuel is below said threshold.

  • Patent number: 10273670
    Abstract: A spill-resistant vacuum breaker valve that includes a check assembly positioned in a valve body and is movable between an open position for allowing water to flow into the valve body through the water inlet and out of the valve body through the water outlet, and a closed position for preventing water from flowing out of the valve body through the water outlet. The check assembly cooperates with a float assembly movable by movement of the check assembly between an open position allowing air to enter the valve body through the air inlet and a closed position sealing the valve body against flow of air into the valve body through the air inlet. The float assembly is adapted to pivot sufficiently to level the float and seal against ejection of water from the valve in the event of non-axial movement of the check assembly in the valve body.

  • Patent number: 10274097
    Abstract: A fill limit vent valve configured for use with a reductant tank includes a valve body, a float and a vapor permeable membrane. The valve body can define an inner chamber and has a valve outlet. The float has a float body configured to be received within the inner chamber and configured to sealingly engage the valve body. The vapor permeable membrane can be configured to permit vapor to pass through while inhibiting liquid from passing through. The float is movable between (i) an open position wherein vapor flows along a first flow path through the valve inner chamber and out of the valve body; and (ii) a closed position wherein the float sealingly engages the valve body and precludes vapor from flowing along the first flow path while allowing flow along a second flow path through the vapor permeable membrane and out of the valve body.

    Abstract: One embodiment relates to a valve device. The valve device includes: a valve case; a valve element slidably disposed within a valve chamber defined in the valve case; and a positive pressure spring configured to urge the valve element toward a valve seat in the valve case. The valve element includes an outer circumferential portion having a predetermined length extending along an inner circumference of the valve chamber. The outer circumferential portion includes plural opening portions. And, ribs project from the inner circumference of the valve chamber to enter into the opening portions, thereby limiting movement of the positive pressure spring in a radial direction.

  • Patent number: 10088182
    Abstract: Devices are provided for ventilating and/or removing volatile chemicals from liquid (e.g. water) stored in a liquid-containing storage tank (e.g. water-storage tank). The devices include a first fluid flow path that is physically isolated from a second fluid flow path and a convection device for moving a first fluid along the first fluid flow path toward at a desired destination and for exhausting the first fluid at the desired destination at a desired velocity. Methods are also provided for ventilating and/or removing volatile chemicals from liquid (e.g. water) stored in liquid-containing storage tanks (e.g. water-storage tanks). The methods involve blowing a first fluid through a ventilation device into a liquid-containing storage device at a velocity sufficient to achieve a desired mass transfer rate of volatile chemicals from the liquid in the liquid-containing storage device to air in the headspace and flowing the contaminated air back through the ventilation device.
