ABSTRACT:
A multiple three and/or two way valve comprising a valve housing having a cylindrical bore defined therein with an inlet port and an outlet port. In one embodiment the valve can have at least one two-way pressure-on, pressure-off outlet and/or a series of pressurizing ports defined in the valve housing communicating into the cylindrical bore. A spool member axially slidable and rotatable is located within the cylindrical bore. The spool member has a blocking ring member extending therearound, a shoulder, and a feed slot. The spool is adapted to be rotated to align the feed slot to either the two-way pressure-on, pressure-off outlet or one of the series of pressurizing ports which are defined in the valve housing radially in a transverse plane to the axis of, and communicating into, the cylindrical bore. Also defined within the valve housing is a plurality of relief ports also disposed in a plane transverse to the axis of, and communicating into, the cylindrical bore. The valve is operated by the movement axially and rotationally of the spool member.
