<p>The invention relates to a rotating actuator (1) comprising a body (2) and a shaft (3) jointly defining at least one operating volume consisting of a an annular cavity which is compartmented by means of at least two partitions (4, 5) extending between two end surfaces (19, 20) of the cavity, one (4) of said radial partitions (4, 5) being respectively borne by the shaft (3) and the other (5) being borne by the body (2) of the actuator and both of said partitions being provided on the opposite free edge thereof with a sealing element (6). The actuator is characterized in that said sealing element (6) fitting the free edge of a partition (4,5) is extended in the direction of each end surface (19,20) of the annular cavity up to each end surface, whereupon it extends into the connection area (19,20) of the end surface and the body (2) or, respectively, shaft (3). Said sealing element with which the shaft (3) or body is fitted is provided in the form of a continuous linear joint provided in kilometer length and which can be cut up as it develops along one edge surface (19) to another according to a loop-shaped trajectory.</p> |
