(57) An electromechanical actuator comprising a body element (1) and an elongate interaction
means (3, 3', 3''), one of which is provided with electromagnetic means (2) and the
other of which comprises ferromagnetic material or a permanent magnet. The body element
and interaction means are arranged with respect to each other so that a rotational
motion may be imparted to the interaction means (3, 3', 3'') by means of a created
magnetic field. The interaction means (3, 3', 3'') is rotatable between two rotational
positions by altering the polarity of the electromagnetic means. When in one rotational
position, the interaction means (3, 3', 3'') is displaceable in a direction of its
rotation axis, by the application of an external force. The interaction means is arranged
to co-operate with the body element (1) in a manner such that they together define
the freedom of operation of the interaction means (3, 3', 3'') in the axial direction.
