ABSTRACT:
A pilot-operated, directional flow control valve includes a movable spool member axially slidable between two positions within a cylindrical bore provided by a multi-ported valve body. An integral portion of the valve body serves as a housing for an inverted, cup-shaped filter element having its lip portion spring-biased downwardly against an annular seating surface. The filter element housing portion of the valve body provides a horizontally extending blind bore functioning as a supply fluid inlet port to the valve. The blind bore inlet communicates with an inlet to the interior of the filter element, the filter element extending perpendicularly upwardly from a point spaced from the terminal end of the blind bore inlet. The orientation of the horizontally extending blind bore inlet relative to the vertically extending filter inlet provides a mechanical filtering action to trap heavy dirt particles at the end of the blind bore before they can enter into the filter element and prematurely clog it.
