ABSTRACT:
A fuel dispenser filter for filtering fuel is adapted to be connected to a support in a fuel distribution system. The filter comprises a housing including an adaptor constructed and arranged to be secured to the support and a bowl operatively connected to the adaptor. A stud/spacer is secured in the adaptor. The stud/spacer defines a centrally disposed outlet flow passage and outwardly disposed inlet flow passages. A sleeve member is movably supported in the adaptor between the stud/spacer and the adaptor. The sleeve member is constructed and arranged to open and close the fuel flow through the inlet flow passages. A filter assembly including filter media is provided in the bowl for filtering the fuel passing through the filter. When the bowl is firmly engaged with the adaptor, the sleeve member is moved to open position to permit the flow of fuel through the filter and when the bowl is removed from the adaptor, the sleeve member is moved to a closed position to stop the flow of fuel. A spring is provided to bias the sleeve member to the closed position when the bowl is removed from the adaptor. Various seals are provided within the filter to confine fuel flow to the desired flow paths.
