The disclosure relates to a piezo actuator device, preferably for controlling a dispensing of an application agent onto a component, including: at least one movable valve body for opening and closing at least one valve seat, at least one preferably pivotable actuating arm for actuating the at least one valve body, and a piezo actuator configured to move the at least one valve body to close and/or open the at least one valve seat.

Piezo actuator device

The disclosure concerns an applicator for applying a coating agent (e.g. sealing agent) to a component, in particular for sealing or bonding a flanged seam to the motor vehicle body component. The applicator in accordance with the disclosure first has a nozzle for dispensing the coating agent in a specific jet direction onto a component surface of the component to be coated. In addition, the applicator has a nozzle carrier for positioning the nozzle. The nozzle carrier is hollow on at least part of its length to pass the coating agent. Furthermore, the nozzle carrier comprises a plurality of limbs arranged one behind the other and angled relative to each other. The nozzle is arranged on the nozzle carrier, in particular on the distal limb of the nozzle carrier. The disclosure provides that a spacer, which projects from the distal limb in the jet direction and rests on the component surface of the component to be coated in the coating operation, is mounted externally on the nozzle carrier and thereby sets a predetermined application distance between the nozzle and the component surface.

Applicator and application method

The disclosure relates to a nozzle device for emitting at least one emission medium onto a component, preferably onto a fold, an edge or a transition joint of the component. The nozzle device comprises at least two nozzle plates arranged adjoining one another, wherein a first nozzle plate comprises at least one opening for emitting at least one emission jet and a second nozzle plate comprises at least two openings for emitting at least two emission jets.

Nozzle device having at least two nozzle plates and at least three openings

The disclosure relates to a nozzle device for emitting an emission medium onto a component, preferably for emitting the emission medium onto two side faces and preferably an end face of a fold, an edge or a transition joint of the component. The nozzle device comprises an opening configuration for emitting the emission medium and is distinguished particularly in that the opening configuration comprises at least two openings for emitting at least two jets of the emission medium and the at least two openings are oriented inwardly so that the at least two jets approach one another toward the emission side.
