Abstract
In one embodiment, a fluid driven actuation system is provided having a turbine and an actuation member with cooperating surfaces. In one form the fluid is fuel. The turbine may move when fluid is flowed through the actuation member thereby causing the actuation member to move by action of the cooperating threaded surfaces. A movable nozzle may also be provided to direct fluid flowing through actuation member and may be used to cause the turbine to move. A spring may be provided to create a biasing force in the nozzle.
