Vent Opening Or Closing On Tipping Container Patents (Class 137/43)
  • Patent number: 11191943
    Abstract: A pressure relief valve for a reservoir has a housing body forming first and second subchambers in fluid communication. A first opening in a bottom surface of the housing body forms a first valve seat. At least one second opening in the bottom surface forms a second valve seat along an outer perimeter. A diaphragm member is biased against the second valve seat and is configured to deflect off of the second valve seat under a negative pressure. A sealing ball is gravitationally biased against the first valve seat and raises off the first valve seat in response to a positive pressure. A cover sheet on an upper surface of the housing body partially encloses the chamber and traps the sealing ball in the first subchamber. The cover sheet includes an aperture aligned with the second subchamber providing an ambient pressure port coupled to ambient atmosphere.

    Abstract: To create a valve for aerating and ventilating a tank comprising a closing element, which is fixed against a valve seat in a closed state so as to form a seal and which is lifted out of the valve seat in an open state, wherein provision is made for a blocking element, which can be moved by means of the force of gravity, by means of which the closing element can be fixed at least in the closed state, which overcomes the disadvantages of the state of the art, which ensures a reliable function even in response to a use under rough conditions with impact loads and which is designed in a simple manner, it is proposed for the blocking element to be accommodated on the closing element so as to be movable.

  • Patent number: 8770218
    Abstract: A casing has a vessel portion, in which a float valve unit is arranged. A fuel drain through-hole having a small diameter is formed at a closed end bottom of the vessel portion. A cross sectional area of the fuel drain through-hole is extremely smaller than an opening area of an inlet port, so that fuel discharging speed of the liquid fuel from the vessel portion through the fuel drain through-hole is suppressed to a small value. As a result, a fuel holding time of the liquid fuel in the vessel portion, which has entered into the vessel portion from the inlet port, is made longer.

  • Publication number: 20140034147
    Abstract: The invention relates to a pressure equalizing valve (5) for a fuel tank or secondary fluid tank on a motor vehicle, comprising at least one valve housing (10), at least one valve body movably arranged in the valve housing (10), at least one venting opening on the tank side and on the connection side or on the atmosphere side, which form a venting path (16) which may be opened or closed by the valve body depending on the position of the tank, when a predetermined transverse force is exceeded relative to a normal force which holds the valve body in a valve seat, the valve body being able to be lifted or deflected from the valve seat and thus opening the venting path (16) and when falling below said transverse force automatically adopting again the position closing the venting path (16). The valve body is configured as a ball (15) and arranged so that when pressure prevails on the tank side, said valve body is held in the valve seat.

  • Patent number: 8573183
    Abstract: Systems and methods for fuel tank tube routing and valve placement to prevent fuel leaks into the evaporative emissions system are disclosed. An embodiment provides a vehicle fuel tank venting system that uses strategically placed valves and a low profile tube routing to prevent the leakage of liquid fuel to an evaporative emission system in the event of a valve failure. In one aspect, a first and second outlet valve may be positioned such that at least one of the valves is above a full fuel level for a desired range of fuel tank tilted positions. Among the desired range, when the first valve is submerged in fuel, at least a portion of the first outlet tube may be above the full fuel level, and when the second valve is submerged, at least a portion of the second outlet tube may be above the full fuel level.
