FIELD: engines and pumps. ^ SUBSTANCE: aerosol generator 11 comprises unit 20 to generate aerosol with larger-diameter drops and unit 42 to generate aerosol with smaller-diameter drops. Airflow runs in main airflow duct 33. Secondary airflow duct 42 branches off main airflow duct 33. Branching section (43a, 40) branches secondary airflow duct 43 off main airflow duct 33 to reduce secondary airflow rate in duct 43. Unit 13, 35 ejects larger-diameter drop aerosol. Larger-diameter drop ejection unit ejects larger-diameter drop aerosol. Said unit 13, 35 is located downstream of said branching section 43a, 40, while unit (14, 42, 49) is located downstream of secondary airflow duct 43. ^ EFFECT: cooling of larger-diameter drop aerosol at stable ejection of smaller-diameter drop aerosol. ^ 9 cl, 6 dwg |
