Patent ID: 8468967

Claim:
A device for applying a flowable medium onto a planar surface of a workpiece, the device having a housing that forms an elongate discharge nozzle for the medium and a medium distributor which is rotatably disposed in the housing and is formed as a cylindrical tube, the medium distributor having a slot extending in the axial direction of the tube, the position of the slot with respect to the discharge nozzle being altered by rotation of the medium distributor, and an outer wall of the medium distributor forming sealing surfaces which engage in a sealing manner against counter-sealing surfaces, the interior of the tube forming a reservoir which can be supplied with the medium by a supply opening, the slot running in such a manner that it can be brought from an open position, in which it forms a through opening from the reservoir to the discharge nozzle, the through opening being open substantially over its entire length, into a closed position in which the through opening is completely closed, characterized in that the counter-sealing surfaces are formed by a sealing strip which is inserted in a cut-out of the housing and has a slit that is aligned with the discharge nozzle; and the medium distributor is pressed with a locally adjustable force against the counter-sealing surfaces flanking the slit by means of pressure pieces that are associated with the housing and are spaced apart from one another in the axial direction of the tube.
