Abstract

PCT No. PCT/SE90/00845 Sec. 371 Date Jul. 23, 1992 Sec. 102(e) Date Jul. 23, 1992 PCT Filed Dec. 18, 1990 PCT Pub. No. WO91/10082 PCT Pub. Date Jul. 11, 1991.A reciprocating axial movement of a drive member (18) in a force actuator is generated by a prestressed tool (17) of Terfenol material being exposed to a pulsating magnetic field. The reciprocating movement is transformed to an axial movement in an application direction of a push rod (21) coaxial therewith. The drive member and the push rod are connected by a connection member (22), which is in self-locking thread engagement with a drive member and the push road and is subjected to a torque from a spiral spring (23) for its rotation during the idle stroke of the reciprocating movement in the direction for advancing the push rod in the application direction.
