Title
(EN) Actuator system with dual chambers
Abstract
(EN)

The present invention relates to an actuator system with a magnetic lead screw, comprises a magnetic rotor and a translator cylinder, the translator cylinder comprises a magnetic stator, the translator cylinder has a closed first end and a second end confined by a lid, the lid having a shaft opening for a shaft coupled to the magnetic rotor, wherein the magnetic rotor, when inserted in the translator cylinder, is arranged to translate a linear movement of the translator cylinder into a rotational movement of the magnetic rotor by using magnetic flux interacting between the magnetic stator and the magnetic rotor, said rotational movements is being transferred through a shaft, the lid with a shaft opening arranged for receiving the shaft, wherein the shaft is arranged to make both the linear and the rotational movement in the shaft opening, the lid being arranged for confining the second end of the translator cylinder, the translator cylinder confined by the lid forms, when divided by the magnetic rotor, a first chamber with a first volume and a second chamber with a second volume, wherein the first volume and the second volume changes as a function of the linear movement. The invention also relates to a method of operating an actuator system with a magnetic lead screw.
