Abstract
Pressurized motive fluid flow passes through a single fluidic vortex orifice to opposite chambers of a differential area, double acting, linear servo-cylinder. While shifting in one direction the vortex orifice severely restricts the flow to the fluid chamber of the motor which is contracting in size so as to permit rapid movement of the piston in that direction, and whenever the piston is moving in an opposite direction the vortex orifice allows substantially unrestricted fluid flow to the same chamber which is now expanding in size, so that the piston can shift rapidly in this opposite direction.
