Abstract
A rotary valve subassembly includes a spool and a sleeve. The spool is positioned within the sleeve and rotatable relative to the sleeve. Rotating the spool relative to the sleeve can align a scalloped recess formed into an outer side surface of the spool with an inner circumferential recess formed into an inner side surface of the sleeve to fluidly-connect a pressurized fluid source and a low pressure fluid reservoir with a hydraulic actuator.
