A bench lily part 8 is provided in the middle of the flow path, and a blowing end 11 of a secondary air induction nozzle 10 is provided so as to face the throat part 9 of this bench lily part 8. In an aspirator for an air conditioner for an automobile, the aspirator for an air conditioner for an automobile is configured to attract air inside the vehicle to a secondary air induction nozzle 10 and to detect the temperature of the air inside the vehicle using an inker sensor 14 provided in the secondary air passage 12. The primary air passage 7 and the portion of the primary air passage 7 that can release air are connected to a discharge passage 31.
The discharge passage 31 is provided with an on-off valve 34 biased by a spring member 33 with a spring force P3, so that the static pressure P1 of the primary air passage is controlled by the discharge passage 3.
1. An aspirator characterized in that the on-off valve 34 opens the discharge passage 31 when the static pressure P2 and the spring force P3 are greater than the sum of the static pressure P2 and the spring force P3.
