1. An applicator for applying a coating agent to a component, comprising:
a) at least one nozzle row having a plurality of nozzles for dispensing the coating agent in the form of a jet from each nozzle of the plurality of nozzles, the nozzles being arranged along the nozzle row and in a common nozzle plane, the nozzles can each be released or closed by a sliding valve needle, and
b) a plurality of actuators for controlled releasing or closing of the nozzles, each actuator of the plurality of actuators having a displaceable actuator needle,
c) wherein the individual actuators each have an outer dimension along the nozzle row which is greater than a nozzle distance between adjacent nozzles of the plurality of nozzles along the nozzle row, and
d) wherein the actuator needles are each connected to the associated valve needle by a mechanical connecting element that includes at least one of a rocker arm or a lifting beam.
