Abstract

The disclosure concerns a printhead for applying a coating agent to a component, in particular for applying a paint to a motor vehicle body component, having at least one outlet opening for dispensing the coating agent, a coating agent supply for supplying the coating agent to the outlet opening, a movable valve element, the valve element in the closed position closes the outlet opening, whereas the valve element in the open position opens the outlet opening, and with a valve actuator for moving the valve element between the opening position and the closed position. The disclosure additionally provides for a flexible membrane which separates the valve actuator from the coating agent supply, the actuator side of the membrane facing the valve actuator and the coating agent side of the membrane being exposed to the coating agent in the coating agent supply.
