A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

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.

A fuel device assembly including a valve assembly and a baffle plate, the valve assembly including a valve cover and a first weld plate provided at an upper end of the valve cover coupling the valve assembly to an interior-facing surface a fuel tank of a vehicle, the baffle plate including a body having a plurality of spaced apart holes formed therein and a housing member extending from the body for receiving and lockingly engaging the valve assembly.

Methods and systems are provided for indication of a degradation in an EVAP and/or fuel system. In one example, a method for indication of a presence or absence of a degradation in a refueling system may include vacuum pull-down and pressure bleed-up tests being carried out based on a state of submersion of a spud valve in liquid fuel in a fuel tank.

A vehicle shown herein is a side by side utility vehicle having frame configured to effectively transfer various loads throughout the frame as whole. The vehicle may further or alternatively include a routing tray configured to retain various fluid lines of the vehicle, a transmission including a passive duct acoustical attenuation device, a door seal configured to allow the frame to contact the seal at an angle, a modular door actuating mechanism, and/or a modular skid plate.

There is provided a fill-up restriction valve including: a housing; and a float valve. The housing includes a housing body including a body-side peripheral wall, and a lower cap including a cap-side peripheral wall, the lower cap being installed to a lower side of the housing body by a joint portion. The joint portion includes an annular groove, an insertion wall portion, and an annular protrusion formed on one of the insertion wall portion and the annular groove, or an annular seal member disposed between the insertion wall portion and the annular groove. The annular protrusion or the annular seal member is configured to be in pressure-contact with the annular groove and the insertion wall portion in a state where the insertion wall portion is inserted into the annular groove.

Methods and systems are provided for diagnosing leaks/degradation in a fuel system. In one example, a system for a vehicle may comprise a variable volume device disposed within a fuel tank; an atmospheric port of the variable volume device fluidly coupled to a vent line upstream of a hydrocarbon sensor housed in the vent line, the vent line coupling a fuel vapor canister to atmosphere; and a controller storing instructions for monitoring output of the hydrocarbon sensor; and generating an indication of a degradation in the variable volume device based on the monitored hydrocarbon sensor. In this way, it is possible to effectively detect a degradation/leak in the variable volume device with minimal specialized components in the fuel system.

A valve member provides for the flow of vapors from a fuel tank of an internal combustion engine to escape the fuel tank. The valve member may include a valve and a boss or spacer. The valve is configured to selectively control the flow of vapor from the fuel tank. The boss or spacer is positioned in a predetermined relationship to the valve, and the boss or spacer prevents a deformation of the valve from disrupting the selectively controlled flow of vapor from the fuel tank.

A filling head for an operating liquid tank, in particular of a motor vehicle, comprising a filling tube with an inlet end, which lies farther away from the tank, and an outlet end, which lies nearer to the tank, the filling tube for conducting operating liquid in a filling direction from the inlet end to the outlet end, a venting arrangement with an inflow end, which lies nearer to the tank and an outflow end which lies farther away from the tank, which end is provided for passing of gas in a counter-flow direction with respect to liquid flowing in the filling direction, in a venting direction extending from the inlet to the outflow end, the venting arrangement is provided, at least in the area of its outflow end, separate from the filling tube, the venting arrangement has a valve with a gas valve body, which is movable between a closed position, in which a gas flow in a valve passage is prevented, and a passage position, in which the gas may flow in the valve passage past the gas valve body, the valve having a liquid valve body, which is movable between a blocking position, in which a liquid flow in the valve passage is blocked, and an open position, in which the valve passage past the liquid valve body is open.
