Beschreibung
Zusammenfassung:	A rotary actuator wherein linear movement of a piston and rack assembly disposed in a unitary housing is converted to precise rotational movement of an operating member mounted to a pinion which operably engages the rack. The operating member extends outwardly from opposite sides of the housing and is adapted for coupling with either a single or a pair of mechanisms for purposes of selectively controlling operation of the mechanisms. The actuator includes new means for locating and supporting the rack, for locating and sealing a pinion assembly in the housing, for precisely controlling rotational movement of the operating member, and for precisely and positively locating mechanism mounting brackets to the housing. The actuator may be either single or double acting.
