摘要： An evaporative emissions canister for use in an automotive evaporative emission system to control emission of fuel vapors to the atmosphere. The canister includes an integrally molded housing having a circumferential side member, a top member and a bottom member; a hydrocarbon-adsorbing material disposed therein so as to provide a vapor adsorbent chamber for adsorbing hydrocarbon fuel vapor flowing therethrough; and an internal membrane located above the vapor adsorbent chamber in the fresh air side of the adsorbent chamber for preventing the fuel vapor molecules from passing through the internal membrane while allowing the air molecules to pass therethrough. The internal membrane is characterized as a cellular fibular material having physical properties sufficient to effectively cause any fuel vapor component molecules and associated pollutants to be sufficiently filtered or separated on the membrane while allowing fresh air molecules to pass freely therethrough.

摘要： A tubular separation system for separating a mixture of hydrocarbons and air at a fuel tank in an automotive vehicle, comprises; a fuel tank containing hydrocarbon fuel and a mixture of hydrocarbon fuel vapor and air; a fuel filler pipe connected to the fuel tank for conveying hydrocarbon fuel from a source of hydrocarbon fuel into the fuel tank; a separation module comprising a membrane for separating the hydrocarbon vapor from air; a first tubular member between the fuel tank and the separation module for conveying the mixture of air and hydrocarbon fuel vapor from the fuel tank to the separation module; a second tubular member between the separation module and the fuel tank for conveying hydrocarbon fuel vapor, separated from the mixture of air and hydrocarbon fuel vapor, from the separation module to the fuel tank; and a third tubular member between the separation module and the fuel filler pipe for conveying air, separated from the mixture of air and hydrocarbon fuel vapor, from the separation module to the fuel filler pipe. A device that provides a pressure differential across said membrane is employed to facilitate the separation of air and hydrocarbon from the air/hydrocarbon mixture. The air containing any residual fuel vapor is directed to an emissions canister where the residual fuel vapor is adsorbed and eventually consumed by the internal combustion engine while the air is released to the atmosphere.

摘要： A fuel vapor storage canister is provided. The canister includes a vapor storage chamber of variable volume, a partition, vapor adsorbing material, and a volume compensator. The partition is movable within the canister and partially defines the vapor storage chamber. The vapor adsorbing material is located in the vapor storage chamber. The volume compensator includes a spring having at least three legs that are deflected by and exert pressure against the movable partition to control the volume of the vapor storage chamber. In one embodiment, the legs of the spring may be evenly spaced to exert a balanced pressure. The spring may include two pairs of opposing legs, where the spring rate between the pairs of legs may vary. The spring may be comprised of two angularly offset band springs and may be formed from a unitary member.
