ASPIRATOR AND VEHICLE AIR CONDITIONER USING THE SAME

摘要

An object is to provide an aspirator capable of increasing the amount of aspirated secondary air and improving performance and to provide a vehicle air conditioner using the same. The aspirator includes a nozzle 15 that aspirates secondary air; a main body 17 that forms a scroll-shaped airflow path 16 on the outer circumference of the nozzle 15; a primary-air inflow path 18 that tangentially communicates with the airflow path 16; and a diffuser that is connected to an open end of the main body 17 and has a throat portion at which a tip portion of the nozzle 15 is disposed. An inner wall 18A of the primary-air inflow path 18, which communicates with the scroll-shaped airflow path 16, is offset outward from the center of the nozzle 15, and primary air introduced from the primary-air inflow path 18 flows into the scroll-shaped airflow path 16 from one direction.
