Dosing system having an adjustable actuator

Abstract

The invention relates to 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 dosing substance, a discharge element (51) arranged in the housing (11) for discharging dosing substance from the nozzle (60), at least one first actuator (20), preferably a piezo actuator (20), coupled to the discharge element (51) and/or the nozzle (60), and at least one second actuator (30), preferably an expansion material element (30), coupled to the first actuator (20). The second actuator (30) is designed to set a position of the at least one first actuator (20) relative to the housing (11), particularly with respect to the discharge element (51) and/or the nozzle (60). The invention further relates to a method for controlling such a dosing system (1).
