The applicator comprises a body (5,6) and an operating component (4). There are medium chambers containing a pressure chamber (13) and an outlet channel (18) opening into a medium outlet (19). There is a shut-off component (20) with a direction of through-flow from the inside outwards, and two back and forth transferable shut-off elements (21,22). A shut-off actuator has a delay unit (30) for delayed release and transfer for the shut-off elements to one position.
