Title:
ROTARY ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2006/070714
Kind Code:
A1
Abstract:
[PROBLEMS] Conventional coming-out of a trunnion pin is prevented to assure stable and smooth movement of a piston. Further, a rotary actuator, a rotary valve, and a connection structure that correspond to a cylinder output and a valve bore diameter are appropriately selectable, the number of parts is reduced, and a cylinder body is shaped so as to have the same cross-sectional shape in its axial direction. [MEANS FOR SOLVING PROBLEMS] Coming-out of a trunnion pin is effectively prevented by a simple structure, a rotary actuator and a rotary valve are connected via an intermediate part, torque is received by the intermediate part, an opening adjustment means is incorporated to simplify the structure of the rotary actuator, and the intermediate part is made replaceable. Further, an indicator section for displaying the degree of opening of the rotary actuator is made to take thrust force occurring when an output is produced. In addition, open side and closed side air passages communicating an air passage are arranged in a side cover.
