Abstract

The device has units that are movable between a position for closing an orifice and a position for opening the orifice. Actuating units displace the movable units between the two positions. Damping units (30) reduce the amplitude of axial vibrations of an injection nozzle holder (10) resulting from the movements of the movable units and/or the action of the actuating units, at a predetermined frequency.
