Abstract
A valve assembly that is useful for controlling fuel delivery utilizes turbine power available from the steady state fuel flow within the valve assembly. A turbine element, which is moved by the steady state fuel flow, provides a motive force to a valve element that controls fuel delivery through selected outlet members of the valve arrangement. A rotating cage valve member preferably is coupled with the turbine element so that the valve member rotates responsive to movement of the turbine element. A controller determines the rate of rotation of the valve member and selectively controls a braking actuator to control the movement of the turbine element and the valve member.
