ABSTRACT:
The control valve uses a rotor assembly to control the flow through the valve. The rotor assembly is rotatably mounted within the valve housing and cooperative with a scroll-shaped means in the flow passage which directs the flow of fluid circumferentially around and then through the bladed portion of the rotor assembly. The rotor assembly converts the motion of the fluid therethrough into rotational movement, thereby creating a predictable pressure drop. Means are provided for varying the pressure drop, namely, by axially positioning the rotor assembly relative to the opening formed by the valve seat.
