ABSTRACT:
The fluid valve assembly includes a hollow movable valve having an open-ended tubular fluid filter in the longitudinal bore of the valve and overlying transverse fluid discharge passages in the hollow valve to filter fluid before it flows through the transverse discharge passages from inside the valve. Downstream of the tubular fluid filter, the hollow valve includes one or more fluid metering passages which are moved relative to a valve seat to control a second flow of fluid from inside the valve. The increased fluid flow longitudinally in the valve bore when the valve is moved from the seat to effect the second fluid flow exerts a washing action on the tubular fuel filter to remove debris or foreign matter therefrom and carry same out through relatively large fluid passages not prone to clogging.
