Dosing system having an adjustable actuator

A dosing system (1) for a dosing substance, which dosing system (1) comprises:

• a housing (11) having a nozzle (60) and a feed channel (64) for the dosing substance,
• a discharge element (51) arranged in the housing (11) for discharging the dosing substance from the nozzle (60),
• at least one first actuator (20) coupled to the discharge element (51) and the nozzle (60) to change a position of the discharge element (51) to discharge or to stop discharging the dosing substance from the nozzle (60),
• at least one second actuator (30) coupled to the first actuator (20), and
• a control unit (80),
• the second actuator (30) being designed to set a position of the at least one first actuator (20) relative to the housing (11) responsive to the control unit (80),
• wherein an entirety of the first actuator (20) is movable in the housing (11) by the second actuator (30), and
• wherein the second actuator (30) is disposed in the housing (11) and is configured to expand or contract to change the position of the discharge element (51) to an adjustment position in combination with the first actuator (20), such that the discharge element (51) is pressed into the nozzle (60) with a predetermined force in the adjustment position.
