Abstract
An application head for dispensing a flowable medium includes a nozzle chamber in the application head and a nozzle needle movably mounted in the nozzle chamber. A supply channel and a supply line introduce the medium into the nozzle chamber. A drive moves the movable element. A lever arm is movably fastened to the nozzle needle and connected to the drive. The lever arm extends through a membrane of a membrane suspension connect the lever arm movably to the application head and form a seal to prevent escape of the flowable medium. Alternatively, a rocker suspension has a lever arm connectable to the movable element and the drive, a plate element has an opening through which the lever arm extends, a rocker mounting device connects the lever arm movably to the application head and a sealing device prevents any escape of adhesive from the chamber through the plate element opening.
