Abstract:
1. A cartridge valve assembly adapted to be disposed in a valve housing defining a cartridge bore, an inlet port, and a return port; said cartridge valve assembly including a main body and a valve portion; said valve portion including a sleeve valve disposed in said cartridge bore, and a spool valve disposed within said sleeve valve for axial movement therein; a spring member operably associated with said spool valve to bias said spool valve within said sleeve valve toward a neutral axial position; an end assembly including a cap member and a manual actuation member moveable from a neutral position, corresponding to said neutral axial position of said spool valve to an operating position; said end assembly defining an internal cavity; said end assembly further including a rotary member disposed in said internal cavity; said end assembly being in sealing engagement with said main body of said cartridge valve assembly; said end assembly being rotatable about an axis of said spool valve of said cartridge valve assembly; characterized by: (a) an axis of said rotary member being substantially perpendicular to said axis of said spool valve; (b) at least one axial end of said rotary member extending through the outer surface of said end assembly; (c) said rotary member being rotationally operable about said axis of said rotary member and including means operable to axially displace said spool valve within said sleeve valve from said neutral axial position to an operating axial position; (d) said movement of said manual actuation member defines a plane of movement that is parallel to said axis of said spool valve; (e) said plane of movement of said manual actuation member being selectively infinitely adjustable about said axis of said spool valve of said cartridge valve assembly; and (f) a locking means being selectively operably associated with said end assembly to restrict rotation of said plane of movement.
