发明名称 A DEVICE FOR DISPENSING DROPS OF A LIQUID
摘要 A device for dispensing drops of a liquid is disclosed. The device comprises a liquid accelerating vessel (11) for receiving a volume of the liquid to be dispensed, a nozzle (14) which is directly mechanically connected with the liquid accelerating vessel (11), a bending element (15), having one portion (17) which is free to oscillate and driving means for causing bending oscillations of the bending element (15). The liquid accelerating vessel (11) has an inlet opening (12) and an outlet opening (13). The nozzle (14) has a passage (22) which is in fluid communication with the interior (21) of the liquid accelerating vessel (11). The driving means comprise a piezoelectric transducer (18) which is directly mechanically connected with the portion (17) of the bending element (15), which portion (17) is free to oscillate.
