Abstract
In a dose setting mode of a dose delivery device, a dose selector is rotated to turn a nut, which thereby moves backward along a thread of a piston rod through a first axial distance. A gearing mechanism transmits the axial movement of the nut to a connector that moves backward, without rotation, through a second axial distance. In a dose delivery mode of the device, the dose selector is pushed forward and drives the connector to move forward through the second axial distance. The gearing mechanism transmits the axial movement of the connector to the nut, which pushes the piston rod forward, without rotation, through the first axial distance. The gearing mechanism includes a first gear that rotates without axial movement relative to the housing, and a second gear that rotates without axial movement relative to the nut.
