  • Patent number: 4605033
    Abstract: A pneumatic positioner is provided with a O-shaped vane that is movably supported at the ends of each of its legs. The nozzle has an air outlet proximate to and aligned with the vane. A nozzle, connected to a source of air under pressure, is attached to a disc for rotation about a central stem that extends through the O-shaped recess. The nozzle has an air outlet proximate to and aligned with the vane. The disc is rotatable about the stem to reposition the nozzle relative to the vane so that air issuing from the outlet of the nozzle can impinge upon the vane at different locations along the length of the vane, intermediate the ends of the legs of the vane. One end of the vane is attached to an input and feedback signal mechanism and the opposite end of the vane is connected to a relay center structure.
