Abstract (en)
The three-position rotary actuator has a first drive unit (2) with a first piston (7) rotatable relative to a first housing (4), and a driven shaft (6) connected to the piston and set in an oscillating rotational movement around a central axis between two end positions when the piston is pressurized by fluid. A coupling component is connected to the driven shaft and executes a pivoting movement relative to the central axis when the driven shaft rotates. A second drive unit (3) co-axial with the first has a second piston (13) and second housing (27) rotatable around the central axis relative to each other and relative to the first housing. The second housing and second piston each have a driver which during a rotational movement execute a pivoting movement in relation to the central axis.

Es wird ein fluidbetätigter Drehantrieb vorgeschlagen, der über eine erste Drehantriebseinheit (2) und eine zu dieser koaxiale zweite Drehantriebseinheit (3) verfügt, die derart miteinander in Wechselwirkung stehen, dass sich ein Dreistellungs-Drehantrieb ergibt, der bei kompaktem Aufbau die Möglichkeit bietet, seine Abtriebswelle (6) in insgesamt drei Stellungen zu positionieren. <IMAGE>
