    摘要： A valve suitable for a fuel tank may include a valve housing having a housing part, and a float configured for closing a vent opening, the float being movably arranged inside the valve housing along a middle longitudinal axis running in an axial direction upward or downward. A lower section of the float faces away from the vent opening and faces toward the housing part of the valve housing. At least one spring element is at least partially arranged in or on the housing part and/or is at least partially formed by the housing part. The spring element contacts the float at least when the float moves downward in the valve housing.

    摘要： There is provided a valve device, including: a housing in which, via a partition wall, a valve chamber is provided below the partition wall and a vent chamber is provided above the partition wall, and a vent hole through which the valve chamber and the vent chamber communicate with each other is provided in the partition wall; and a float valve. A valve seat is formed on a side of the valve chamber of the partition wall, and an opening is provided on an inner side of the valve seat. The opening includes a first opening and a second opening extending outward in a slit shape from an outer periphery of the first opening. A seal part having elasticity that contacts with and separates from the valve seat to close and open the first opening and the second opening, is disposed above the float valve.

    摘要： Methods and systems are provided for performing a reverse purge of an evaporative emissions canister in a vehicle with a sealed variable volume fuel tank. In one example, a method may comprise in response to an ambient temperature reducing during a diurnal temperature cycle, and further in response to the EVAP canister loaded with fuel vapors above a threshold, closing a valve positioned at an atmospheric port of the fuel tank and opening a fuel tank isolation valve. In one example, the fuel tank isolation valve may be in fluid communication between the fuel tank and the EVAP canister. In this way, it is possible to convert a sealed variable volume fuel tank to a vented pressurized fuel tank and initiate a reverse purge during the cooldown hours of the diurnal temperature cycle.

    摘要： A fuel system having a fuel tank, a filler pipe for adding liquid fuel, a carbon canister for collecting fuel vapors from the fuel tank during a refueling operation, a stepper motor and a stepper driven valve for controlling fluid communication between the fuel tank and the canister, where the valve is configured to be positionable in a closed position, an open position creating a passageway with a first size, and one or more intermediate positions each creating a passageway with a size which is smaller than the first size and having a moving element, movable relative to a valve opening between a closed position and an opened position, the moving element having: a sealing means for making a leak tight seal and, a deflecting means for controlling the fluid flow, where the deflecting means protrudes inside the valve opening and is adapted to be located upstream relative to sealing means.

    摘要： The invention relates to a leak detection system on board of a vehicle comprising a fuel tank (301, 401), a filler pipe (302, 402), a venting line (303, 403) for recirculating fuel vapors from the tank to the filler pipe, said system having a combination pressure and temperature sensor mounted in the vapor dome of the fuel tank, and a pressure sensor located in the recirculation line above the highest possible liquid level that could be present in the recirculation line and to methods to detect said leak.
