Abstract
Apparatus for providing a linear movement to an actuating member while preventing axial loadings from being transmitted from the actuating member to an engaging member, such as a screw. A pressure pad or springs are interposed between an actuating member and an engaging member such that axial loadings are prevented from being transmitted from the actuating member to the engaging member due to the resilient effect of the springs or pressure pad.
Claims16
Actuator, comprises a housing, a motor, an actuating member and a screw mechanism providing linear movement of the actuating member with respect to the housing in response to a rotational movement of the motor, said screw mechanism comprising a screw and a nut one of which is rotatably supported with respect to the housing, characterized in that the screw mechanism and the actuating member engage each other through a resilient pressure pad comprising two generally parallel wall members, said wall members being mutually connected along their circumference and enclosing a closed internal space which is filled with a fluid.
