Abstract (en)
The pump has a thrust member (20) fixed to a connecting rod (19), where the member is axially movable in a longitudinal axis in a magnet shroud (17). A magnetizing coil magnetizes a magnet in the shroud, for drawing the thrust member and the rod into the shroud against the force of a recuperating spring (23), so as to make an air gap between the member and the shroud small. A control device influences an actual stroke path executed during a forward motion of the thrust member independent of a measured dead region due to the elastic deformation of a diaphragm (13) connected to the rod.
