A flow selector valve is described in which a valve housing with a central bore is provided. The housing includes a plurality of axially spaced discharge openings and an intake opening openly communicating with the central bore. An elongated spool member, complementary to the central bore of the valve housing is slidably mounted in the central bore for axial movement therein. The spool member includes an internal chamber extending axially from a closed end within the spool member to an open end. The open spool end is in open communication with the intake opening of the housing. The spool member also includes at least one gate opening between the external spool surface and its internal chamber. A driver is connected to the spool member for selectively moving the spool member axially within the bore. The gate opening is movable between (a) a closed condition wherein the discharge openings are closed by the external surface of the spool member and (b) an open condition where the gate opening is aligned with a selected one of the discharge openings to thereby provide a flow path through the valve from the intake end through the selected one of the discharge openings.

Abstract

A flow selector valve is described in which a valve housing with a central bore is provided. The housing includes a plurality of axially spaced discharge openings and an intake opening openly communicating with the central bore. An elongated spool member, complementary to the central bore of the valve housing is slidably mounted in the central bore for axial movement therein. The spool member includes an internal chamber extending axially from a closed end within the spool member to an open end. The open spool end is in open communication with the intake opening of the housing. The spool member also includes at least one gate opening between the external spool surface and its internal chamber. A driver is connected to the spool member for selectively moving the spool member axially within the bore. The gate opening is movable between (a) a closed condition wherein the discharge openings are closed by the external surface of the spool member and (b) an open condition where the gate opening is aligned with a selected one of the discharge openings to thereby provide a flow path through the valve from the intake end through the selected one of the discharge openings.
