摘要： A fill limit vent valve configured for use with a reductant tank includes a valve body, a float and a vapor permeable membrane. The valve body can define an inner chamber and has a valve outlet. The float has a float body configured to be received within the inner chamber and configured to sealingly engage the valve body. The vapor permeable membrane can be configured to permit vapor to pass through while inhibiting liquid from passing through. The float is movable between (i) an open position wherein vapor flows along a first flow path through the valve inner chamber and out of the valve body; and (ii) a closed position wherein the float sealingly engages the valve body and precludes vapor from flowing along the first flow path while allowing flow along a second flow path through the vapor permeable membrane and out of the valve body.

摘要： A fuel tank vent apparatus for controlling discharge of fuel vapor from an interior region in a fuel tank includes a housing and a valve received in the housing that moves between an open position and a closed position. The valve assumes the open position when the fuel level in the fuel tank is relatively low and the valve assumes the closed position when the fuel level in the fuel tank is relatively high.

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.

摘要： The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a piston assembly which includes a main disc, a piston head located above the main disc, a float below the main disc, and a float shaft joining the float to the piston. When no media is in the valve the float is at the bottom of the valve and the main disc is down, allowing gases to leave the valve. The float is lifted as media enters the valve, thus using buoyancy to lift the main disc into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve.

摘要： A valve device is attached to a fuel tank. The valve device includes a case including a vent valve port communicating outside of the tank at an upper portion, and including an inflow portion for a fuel below the vent valve port; and an upper floor body inside the case and rising by the fuel flowing into the case to be seated in the vent valve port. In a face portion facing a bottom portion of the upper float body in the case, an elastic piece is formed by a first arc-shaped split groove such that a center side of the face portion becomes a curvature inner side, and a second arc-shaped split groove formed such that a center of the face portion becomes a curvature inner side outside the first arc-shaped split groove. One portion of the elastic piece abuts against the bottom portion of the upper float body.
