摘要： An evaporative emission control and leak detection system for a vehicle is provided. The system includes an integrated valve module in fluid communication with a carbon canister and atmosphere. The module is arranged to vent the system when exposed to predetermined high negative and positive pressure conditions. The module includes a switch mechanism having a spring biasing member arranged to bias the switch mechanism to an open position. The switch is operable to indicate when the system is in a low negative pressure condition. The switch also includes a negative pressure valve coupled to a fluid passage between the canister, the atmosphere and the switch, and a positive pressure valve coupled to a fluid passage between the canister and atmosphere that bypasses the negative pressure valve and switch. The negative and positive pressure valves are positioned in a stacked arrangement in the integrated valve module.

摘要： Reducing fuel vapor within a vehicle fuel tank is accomplished by employing a flexible fuel sock attached to spud near the top surface of the fuel tank. The fuel sock resides within the fuel tank and retains liquid fuel during tank refueling so that the fuel is confined within the fuel sock until the fuel reaches the bottom of the fuel tank or the current level of fuel within the tank. The fuel conduit may be flexible and buoyant to accommodate any level of fuel in the tank and reduction of fuel refueling vapors. A check valve may be situated within the spud.

摘要： A fuel vapor vent valve assembly for a vehicle fuel tank for venting fuel vapor from the fuel tank to a fuel vapor emission device disposed external of the fuel tank, wherein the assembly comprises a valve housing having a fuel vapor vent outlet opening or orifice defined by a valve seat and communicating with a fuel tank vapor space interior of the fuel tank and with a fuel vapor emission device, such as a charcoal canister, exterior of the fuel tank. A fuel level responsive valve-moving device, such as a float, is disposed in the housing for movement therein. A vapor vent valve is disposed on the device in a manner for closing and opening the vent orifice in response to the fuel level in the fuel tank. The vent valve includes a partial spherical, radius-defined sealing surface that mates with a sealing surface of the valve seat to provide liquid/vapor tight sealing relation therebetween when the valve is in the closed position relative to the valve seat. The vent valve includes an axle about which the valve surface is rotated relative to the valve seat surface in response to initial downward movement of the valve-moving device when the valve and valve seat surfaces are in sealing relation. The valve surface is configured such that a small degree of rotation of the valve relative to the valve seat interrupts or breaks the sealing relation therebetween, providing a vapor flow path that reduces the pressure differential across the valve to facilitate its reopening by further downward movement of the valve-moving device.

摘要： A tank venting apparatus or a fill-limit and tank ventilation valve is disclosed for use with a fuel tank. The valve has a housing which contains a first valve assembly, second valve assembly, third valve assembly and fourth valve assembly. The first valve assembly primarily communicates with the fuel tank. The fourth valve assembly communicates with a vapor recover canister and a filler neck to the tank. The first valve assembly also communicates with the third valve assembly and the second valve assembly. The second valve assembly generally communicates with the first valve assembly and the third valve assembly. The third valve assembly communicates with the first valve assembly, second valve assembly and fourth valve assembly. The third valve assembly prevents passage of liquid fuel from the tank to the canister. The fourth valve assembly manages flow from the valve.
