Abstract
Examples are provided that describe a rotary hydraulic valve. In one example, a rotary valve comprises a sleeve with a plurality of selector ports and one or more control ports spaced along a length of the sleeve. A spool comprising an internal chamber is provided within the sleeve. The spool includes a plurality of selector openings and one or more control openings spaced along a length of the spool. The rotary valve also comprises a controller for determining a given rotational movement of the spool based on a selection of a pressurized fluid. The rotary valve also comprises a motor coupled to the spool and for rotating the spool within the sleeve based on the given rotational movement. The motor is configured to cause a given alignment of the spool to the sleeve resulting in a pathway through the internal chamber of the spool and out to the sleeve.
