摘要:
An assembly (16, 216) mountable to a fuel tank (11, 210) and connectable to a carbon canister (17) includes a housing (18, 118, 218) defining an internal cavity (32, 132, 232). A vapor vent valve (36) is configured to permit fluid communication from the fuel tank through the vapor vent valve from an inlet (38) to an outlet (40), and in all cases is isolated from the internal cavity so that fluid flows through the vapor vent valve from the inlet to the outlet without fluid communication with the internal cavity. A first vent line (64) connects the outlet of the vapor vent valve with a first port (60) of the housing. A second vent line (72) connects a second port (62) of the housing with the carbon canister. At least a portion (74, 78) of the first vent line is above a predetermined liquid fuel level (75) within the tank when the assembly is mounted to the fuel tank and tilted at up to a predetermined angle (76).

A self-regulating pressure throttle configured for use in a fluid conduit includes a throttle body having a series of segments. The throttle body includes an inlet end and an outlet end. The throttle body includes a cone portion and a rim portion. The cone portion tapers away from the rim portion from a first end to a second end. The second end includes a nozzle orifice. The series of segments can be formed on the cone portion. The series of segments are configured to move between (i) a first position wherein the nozzle orifice has a first diameter and (ii) a second position wherein the nozzle orifice has a second diameter. The second diameter is smaller than the first diameter. The series of segments can be configured to move from the first position to the second position upon an increased pressure flow of fluid at the inlet end.

An assembly (10) is provided that integrates a jet pump (44, 144) with a liquid trap to drain liquid fuel from vapor flow, such as vapor vented from a fuel tank (22). The assembly includes a housing (12) that has a liquid trap (20) configured to trap liquid carried in vapor flowing through the housing. A jet pump (44, 144) has a venturi nozzle (48, 148) and is in selective fluid communication with the liquid trap so that liquid flow through the venturi nozzle induces draining of the liquid trap.

A valve configured for use with a fuel tank can have a floating main valve housed within a valve body. The valve body can define a first port fluidly connected to the fuel tank, a second port fluidly connected to a tank venting system of the fuel tank and a third port fluidly connected to the filler neck. The solenoid can be configured on the check valve. The solenoid can have a pin configured to extend into the valve body and engage the floating main valve in a locked position.

A self-aligning jet pump assembly for draining a liquid trap has a jet pump nozzle and a nozzle carrier that are self-aligning. An assembly is provided that enables a constant axial force between a first component and a second component over a range of operating conditions. The assembly can be used to provide a constant axial force on supported components, such as the self-aligning jet pump assembly.
