A filtration devicefor filtering air used with a fuel vapor recovery systemmay comprise a housing comprising an upper endhaving at least one air inletand a lower endhaving at least one air outlet, a first passagewayin fluid communication with the air inletand configured to increase the velocity of the air through the first passagewaycompared to the air inlet, a collection cavityin fluid communication the first passagewayand configured to reduce the velocity and abruptly change the direction of the air through the collection cavitycompared to the first passageway, a filter cavityin fluid communication with the collection cavitycomprising a filtering media, and a clean air cavityin fluid communication with the filter cavityand the air outletof the housing.

Filtration device for use with a fuel vapor recovery system

A three-port valve includes a valve body including a first port, a second port, and a third port, the first port having a first valve orifice and the second port having a second valve orifice. The valve may also include a first valve closure member and a second valve closure member, the first and second valve closure members may be configured to selectively seal the first and second valve orifices, respectively. The valve may further include a solenoid including a first coil and a second coil, at least one of the first and second coils configured to actuate at least one of the first and second valve closure members when energized. Additionally, the valve may include an electrical connection configured to selectively and individually energize the first and second coils. The valve may be configured to operate in at least three different states of operation. For example, the three-port valve may have a first state (e.g., a default state) when neither coil is energized, a second state when first coil is energized to move only one of the valve closure members, and a third state when the second coil is energized to move both valve closure members.

Three-port valve

A filtration device for use in filtering air used to purge a vapor storage canister used in connection with a fuel vapor recovery system of an automobile. The device includes a housing. In some instances, the housing may be integral to another component. The housing has a chamber having an arcuate inner surface. Air flowing into the chamber through an inlet port strikes the arcuate interior surface and is redirected such that the air rotates in said chamber. The centrifugal force of the rotating air filters out any contaminants of sufficient mass contained therein. The filtered air is removed via an outlet port positioned near the longitudinal-axis of the chamber. Contaminants removed from the air fall due to gravity or a secondary air flow pattern into a collection portion of the housing.
