ABSTRACT:
A hollow cylindrical amplifier driven actuator spool has first and second vortex chambers divided by an internal piston. A shaft is attached to the pistion and extends out the cylinder. Fluid logic controls the fluid flow in the vortex chambers so that the resulting chamber pressure causes the piston to accelerate. The use of beam deflection amplifiers for fluid control in connection with a push-pull vortex amplifier arrangement results in a device with low fluid flow leakage.
