Abstract
A filter box having an integrated vent solenoid to connect to the atmospheric port of an automotive emission storage canister in relation to the fuel tank of the vehicle, used to recapture fuel vapor before it is released into the atmosphere. The filter box with integrated vent solenoid is sealed to the atmospheric port of the canister, and consists of a filter housing with an internal feature to house and retain a vent solenoid, an optional foam filter to protect the vent solenoid and the canister against dust, and a filter cap to retain the filter foam. A closed cell foam or rubber O-ring provides a sealing between the filter cap and the filter housing. A labyrinth-type filter means is integrated within the cap of the filter box assembly and provides for separation of the air and dust traveling through the filter box, and a further sealing means provides a leak tight seal between the filter box and the canister.
