Abstract:
The invention relates to a transmission arrangement for controlling a force of a translation, the transmission arrangement comprising a drive collar (13) connectable to a translative drive means (11) and prevented from rotating with respect to a ground (12) of the drive means (11), a flange face of the drive collar (13) bearing against a mating flange face of a friction collar (20), the friction collar (20) slidable in longitudinal direction and rotationally constrained by engagement in a cam track (12.3), another flange face of the friction collar (20) bearing against a mating flange face of a plunger (8), the plunger (8) slidable in longitudinal direction and prevented from rotating.
