Abstract
In an implementation, a hydraulic valve includes a valve body, a cylindrical chamber within the valve body, and a cylindrical spool within the chamber. The spool is rotatable between at least a first position and a second position about a longitudinal axis parallel to a longitudinal axis of the chamber. The spool includes a landing and an eccentric channel that extends around a portion of an outer circumferential surface of the landing. In the first position, an inlet and an outlet of the hydraulic valve are fluidly coupled by the eccentric channel to allow a flow of a hydraulic fluid circumferentially around the landing from the inlet to the outlet. In the second position, the inlet and/or the outlet are obstructed by another portion of the outer circumferential surface of the landing to prevent the flow of the hydraulic fluid from the inlet to the outlet.
