Vent Opening Or Closing On Tipping Container Patents (Class 137/43)
  • Patent number: 9713692
    Abstract: A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

    Abstract: A fuel vapor vent valve assembly includes an anti-trickle valve having a casing defining a first cavity. A movable element is disposed within the first cavity. The casing defines a lower dynamic vapor passage in fluid communication with an interior of a fuel tank. A concave ramp is disposed concentrically about the lower dynamic vapor passage, within the first cavity. The movable element moves upward along the concave ramp in response to a change in motion to open fluid communication through the lower dynamic vapor passage to vent vapor pressure from within the fuel tank during movement.

  • Patent number: 8365757
    Abstract: A valve body and a float body are combined by respectively coupling two or more coupling parts provided on one of the valve body and the float body to coupled parts provided on the other of the valve body and the flat body in a state allowing upward and downward movements of the valve body. During descent of the float body, one coupling part of the two or more coupling parts is caught on the coupled parts ahead of the other coupling parts whereby the valve body is tilted, and the other coupling parts restrict the tilting of the valve body.

  • Patent number: 8365756
    Abstract: A valve body and a float body are coupled so that the valve body is allowed to move in a direction along a central axis of movement of the float body, and the seated valve body is unseated when the float body descends. On a central axis side of the movement of the float body, a pair of guide members is provided, and when the valve body tilts, the valve body and the float body contact each other on a lower side of a tilt of the valve body and the float body ascends, so that the guide members correct the tilt. Also, when the float body ascends, the float body and the valve body do not contact each other in a rest of a portion.

  • Patent number: 8307840
    Abstract: A valve device is used by being attached to a fuel tank. The valve device includes a main body portion provided with ventilation openings which become an inner end of a connecting passage with the outside of the fuel tank, a valve body opening and closing the ventilation openings using a liquid surface of a fuel, and a skirt portion extending down from the main body portion so as to surround the valve body, and also constructed so as to admit fuel due to a pressure difference between inside and outside of the fuel tank when the liquid surface of the fuel reaches a cuff portion of the skirt portion.

  • Patent number: 8297298
    Abstract: In a vent control valve for a fuel tank, a housing receiving a float assembly therein is provided with a communication hole passed across a wall of the housing, and an opening of the communication hole facing an interior of the housing is directly exposed to an interior of the housing when the float assembly is in a low position and overlaps with a peripheral wall of the float assembly when the float assembly is in a high position. By suitably selecting the size of the communication hole and/or the number thereof, a desired delay in the dropping of the liquid fuel level in the housing following the filling up of the fuel tank can be achieved. Thereby, overfilling of the fuel tank can be avoided.

  • Patent number: 8230873
    Abstract: A valve assembly is provided that permits adjustable vent flow from the fuel tank vapor space through a bypass vent opening based on a condition in the vapor space after nozzle shutoff. The valve assembly including a first valve, also referred to as a main float, that provides rollover protection and controls venting of the vapor space prior to nozzle shutoff. A secondary closure device, also referred to as a second valve, moves independently of the first valve to control venting of the vapor space after nozzle shutoff through a bypass vent opening formed in the valve housing in response to at least one operating condition in the fuel tank outside of a chamber defined by the valve housing in which a main float moves.

  • Patent number: 8231110
    Abstract: A roll-over valve attaches over an existing carburetor float bowl vent tube and closes when a car is involved in a crash to prevent or reduce fuel from escaping from a tilted or inverted carburetor and starting a fire. Carburetors are used in many special interest cars and race cars. The carburetors include float bowls containing fuel and the float bowls are vented to outside air by the carburetor vent tubes. The carburetor vent tubes are generally vertical tubes reaching upward from the carburetor into an air cleaner or the volume above the carburetor. The roll-over valve includes a compression fitting or other connector and is easily fitted to the carburetor.

  • Patent number: 8171952
    Abstract: A fuel vapor vent valve assembly is provided that may include a float valve and an isolation valve arranged in series with each other. Bypass openings in the valve assembly create multiple flow paths as the float valve and the isolation valve respond to changes in fuel tank pressure and fuel level. The control valve assembly may include a housing defining a chamber with a main opening configured to open the chamber to the tank, a vapor vent passage and a first bypass vent opening. A float in the chamber closes the vapor vent passage when fuel in the chamber is at or above a predetermined level. The first bypass vent opening vents the tank to the chamber even when the fuel covers the main opening. A feature on the float provides a metered opening of the vapor vent passage between closed and fully open based on float position.

  • Patent number: 8141576
    Abstract: Provided is a float valve device which allows a valve to be quickly opened when, in a state in which a float has been raised as a result of a rise in fuel liquid level to close the valve, the fuel liquid level is lowered again. The float valve device includes a housing, a float accommodated in the housing, a movable valve adapted to abut a valve seat to close an opening, and a retention frame to retain the movable valve so as to allow the movable valve to ascend/descend by a predetermined distance and to incline with respect to the float. Further, a circumferentially uneven protrusion is formed on a portion where the retention frame and the movable valve abut each other. When the float is lowered in a valve-closed state, the protrusion first abuts the movable valve to impart a lowering force thereto.
