Patent ID: 11498092

Abstract:
The invention relates to a dosing system (1) for a dosing material having a nozzle (40), a feed channel (44) for dosing material, a discharge element (31), an actuator unit (10) that is coupled to the discharge element (31) and/or the nozzle (40) and has a piezo actuator (60), and a cooling device (2). The cooling device (2) comprises a supply device (21, 24, 26) for feeding a precooled cooling medium into a housing (11) of the dosing system (1). The cooling device (2) is configured for direct cooling of at least one subregion of the piezo actuator (60) and/or at least one subregion of a movement mechanism (14) coupled to the piezo actuator (60) by means of the precooled cooling medium.
