ABSTRACT:
A rotary servo or throttle valve comprises a housing defining a chamber and discharge port in fluid communication with the chamber, a rotary valve spool for delivering fluid into the chamber, and a system for delivering pressurized fluid passing from the outlet opening of the valve in the chamber to the discharge port in the housing in which non-cavitating technology can be readily incorporated. The outlet opening of the valve spool is a wedge shaped groove formed in its periphery, the groove having opposed, arcuately diverging sidewalls. The diffusing system comprises an elongated member which may be rotated in the chamber to align a plurality of flow paths with the discharge port and the outlet opening. The elongated member and valve spool may be rotated independently in opposite directions to obtain faster flow rate changes.
