Abstract:
The present invention relates to an aspirator for a vehicle air conditioning system, the aspirator comprising an internal flow path through which air from inside an air conditioning case is introduced and which discharges the air to one side, and an interior air suction pipe of which an inlet communicates with the inside of a vehicle and an outlet communicates with the internal flow path, and which suctions the air from inside the vehicle on the inlet side according to negative pressure on the outlet side formed by discharge air pressure of the internal flow path, wherein the internal flow path is provided with: an air inlet through which the air from inside the air conditioning case is introduced; a bent portion which is bent at a predetermined angle from the air inlet; a throat portion of which the cross-sectional area gradually narrows radially inward from the bent portion; a pipe expansion portion of which the cross-sectional area gradually expands from the throat portion toward an air discharge outlet; and an air flow control member formed at a predetermined height on an air flow path between the bent portion and the throat portion so as to control the flow of air flowing from the bent portion to the throat portion downstream therefrom.
