ABSTRACT:
A valve for controlling flow of hydraulic fluid. The valve includes a valve sleeve and a valve core. The core is disposed within the sleeve. The core and sleeve are relatively rotatable. The sleeve has grooves connected to a utilization device. The core has grooves connected to a fluid supply and reservoir. The core and sleeve have lands which radially overlap during relative rotation of said core and sleeve to restrict fluid flow from a portion of the grooves in the sleeve to the grooves in the core connected to the reservoir. The lands on the sleeve have chamfered end faces with tapered segments.
