<p>The invention relates to a pressure medium operated actuator, such as a torque link or like, which is meant to produce by means of a pressure medium being led therein a rotative motion (w) in one plane of at least one of its output ends (I). The actuator has at least fastening and coupling means (K) for fastening thereof to a utilization target and coupling thereof to a pressure medium system driving the same and a pressure medium arrangement for carrying out a pressure medium function of the actuator by a piston, being movable in a pressure room by influence of the pressure medium, and by a swivel member, whereby the swivel member by means of its rotation (z) in one plane brings about the desired rotative motion (w) of the actuator's output head (I). The pressure medium arrangement belonging to the actuator and its swivel member are arranged at least as one built-in pressure medium unit (1), whereby the piston (lb), moving in the pressure room (la) by rotating (z), when viewed in a crosswise plane (p) perpendicular to the longitudinal direction (s) of the actuator, around a centerline (x) parallel with a longitudinal direction (s) of the actuator, acts as the swivel member that produces the rotative motion (w) of the actuator's output head (I).</p> |
