Beschreibung
Zusammenfassung:	A hydraulically balanced assembly is provided. The assembly includes: a valve body defining a tapered axial passageway; and a rotor having a tapered outer diameter such that the rotor has a first portion having a wider diameter and a second portion having a smaller diameter, the rotor being dimensioned to fit within the axial passageway of the valve body, the rotor further defining a rotor axial passageway having a first passageway portion and second passageway portion, the rotor further defining a first and second port, where each of the first and second ports provide fluid communication between the tapered outer diameter and the rotor axial passageway, wherein the first and second portions define openings having different cross-sectional areas where the first passageway portion is located in a first portion of the rotor and a second passageway portion is located in the second portion of the rotor and the difference in cross-sectional areas between the first passageway portion and second passageway portion and the amount of taper of the outer diameter of the rotor are related according to the Landrum relation.
