Abstract

Rotary actuator for operating a member that performs only limited rotational movement, for example the shaft of a butterfly valve and which comprises a double-acting piston moved by fluid pressure and mounted with its longitudinal axis perpendicular to the longitudinal axis of said member, cooperating with the latter by means of a rack and pinion device comprising a rack on the piston, or a piston rod connected thereto, as well as a sector of a pinion fixed to the rotating member, characterized in that the passage of the the teeth of the rack and the pinion sector are selected in such a way, and the outermost gaps between two teeth of the rack are enlarged in such a way that a certain dead axial movement of the piston is produced, so that when the latter remains in any of its terminal positions, the penultimate tooth of the pinion sector is located directly bracket the outer, fully defined tooth of the rack is locked to lock the mechanism in the corresponding terminal position until pressurized fluid is supplied to move the piston in the opposite direction.
