A DROP BENT DEVICE FOR VEHICLE INDOOR USING SONIC NOZZLE JET PUMP

摘要

The present invention relates to a device for generating a downdraft in a car using a sonic nozzle jet pump. To describe in more detail, a suction force is generated by using kinetic energy of exhaust gas, and the suction force is lowered on the driver's floor using the suction force. A device for operating the airflow generating device, the configuration of which is composed of an exhaust gearbox 11, an exhaust pipe 12, a nozzle 13, a sonic nozzle suction pipe 14, a non-return valve 15, and a corrugation protrusion 16. It consists of the nozzle pump 1, the suction plate 21, and the downdraft generator 2 which consists of the replaceable filter 22. As shown in FIG.
