Vacuum Ejector and Vacuum Apparatus Having the Same |
摘要 |
A vacuum pump ejector may include ejector body and a nozzle. The ejector body may have a passageway through which fluids may flow. The passageway may have an orifice. The nozzle may inject a purging gas to the orifice. The ejector may decrease a pressure between the vacuum pump and the scrubber, so that the vacuum pump may have improved efficiency. Thus, the vacuum pump may be effectively operated.
