Abstract
An assembly is provided that integrates a jet pump with a liquid trap to drain liquid fuel from vapor flow, such as vapor vented from a fuel tank. The assembly includes a housing that has a liquid trap configured to trap liquid carried in vapor flowing through the housing. A jet pump has a venturi nozzle and is in selective fluid communication with the liquid trap so that liquid flow through the venturi nozzle induces draining of the liquid trap.
Claims21
An assembly comprising:
- a housing having a liquid trap configured to trap liquid carried in vapor flow into an interior cavity of the housing;
- wherein the housing has a first opening through which the liquid trap drains;
- a valve configured to be selectively movable between a closed position and an open position;
- wherein the valve closes the first opening to prevent draining of the liquid trap through the first opening when the valve is in the closed position, and allows draining of the liquid trap through the first opening when the valve is in the open position;
- wherein the valve includes:
- a valve body with a generally cone-shaped end that extends into the interior cavity;
- and
- a spring that biases the valve body to the closed position.

A system comprising:
- a fuel tank having a fuel pump;
- an engine to which fuel is provided through a fuel discharge line from the fuel pump;
- a fuel vapor recovery device;
- a vapor vent valve operatively connected to the fuel tank and operable to communicate fuel vapor from the fuel tank to the vapor recovery device;
- a liquid trap assembly operatively connected to the fuel tank and including:
- a housing having a liquid trap configured to trap liquid carried in the fuel vapor flowing from the vapor vent valve into the housing;
- wherein the housing has a first opening;
- a valve configured to be selectively movable between a closed position and an open position;
- wherein the valve closes the first opening to prevent draining of the liquid trap through the first opening when the valve is in the closed position, and allows draining of the liquid trap through the first opening when the valve is in the open position;
- wherein the valve includes:
- a valve body with a generally cone-shaped end that extends into the interior cavity;
- and
- a spring that biases the valve body to the closed position.
