摘要： A valve device for a fuel tank includes: a housing in which an opening is formed in a partition wall, and a fuel vapor discharge port is provided; and a float valve. A ventilation chamber is provided with a tubular wall that is configured to communicate with the fuel vapor discharge port, and a notch is formed in a lower portion of a tip portion in an extending direction of the tubular wall. The partition wall includes a ceiling wall in which the opening is formed, and a peripheral wall extends downward from a peripheral edge of the ceiling wall. A part of the peripheral edge of the ceiling wall and a part of the peripheral wall are positioned inside the tubular wall through the notch when viewed in an axial direction of the tubular wall and a valve axial direction.

摘要： A tube extends through an attachment section and defines a vapor passageway. A housing is supported to the attachment section for movement between several positions relative to the attachment section. The housing defines a float chamber below the tube. A valve seat portion is located within the float chamber and has an engagement part, a sleeve part and a seat surface. The engagement part is connected to the housing. The sleeve part telescopically engages the tube and is movable along the tube with the housing. The valve seat portion defines a central bore open to the vapor passageway and the seat surface. The float moves within the float chamber. When to fluid enters the float chamber the float floats up against the seat surface closing off the central bore and the vapor passageway. In the absence of fluid the float moves downward exposing the seat surface.

摘要： A valve assembly for a tank of a vehicle and a method of creating a vacuum are disclosed. A valve body defines a cavity and an outlet in fluid communication with the cavity for venting the tank. The assembly includes a seat disposed in the cavity of the valve body. The seat separates the cavity into first and second cavity portions. The seat defines an aperture to provide fluid communication between the first and second cavity portions. The assembly includes a cover device disposed between the seat and the outlet. The cover device defines at least one hole therethrough. The cover device is movable between a rest position engaging the seat to minimize fluid communication between the aperture and the hole and an actuated position spaced from the seat to increase fluid communication between the aperture and the hole when a vacuum is created in the first cavity portion.

摘要： A fuel cutoff valve comprises a casing having a primary valve chamber and a secondary valve chamber, a primary valve mechanism housed in the primary valve chamber, and a secondary valve mechanism housed in the secondary valve chamber. The casing has a first communication path that connects the inside of the fuel tank and the primary valve chamber, and a second communication path that connects the primary valve chamber and the secondary valve chamber, due to the differential pressure between the tank internal pressure and the primary valve chamber, by the fuel in the fuel tank flowing into the primary valve chamber through the first communication path, a connection conduit is closed by the primary valve mechanism. When the fuel level inside the fuel tank reaches a second fuel level, the second communication path is closed by the rising of the secondary valve mechanism.

摘要： A casing includes a container in which a float valve is disposed. When the float valve is closed, the casing keeps the float valve in a closed state for a relatively long period of time. A sub-float valve is provided below the container in the casing, and is closed by floating on fuel at the time of a turn of a vehicle or an automatic stop of first refueling. When the first refueling is completed, air in the sub-float valve is discharged, and the sub-float valve loses its floating function.
