High Vacuum Ejector |
| 摘要 |
An ejector for generating a vacuum comprising a first stage. The first stage comprises a drive nozzle and a ring drive nozzle. The drive nozzle is for generating a drive jet of air from a flow of compressed air and directing the drive jet of air into a first stage expansion nozzle in order to entrain air in a volume surrounding the drive jet of air into the jet flow to generate a vacuum across the first stage. The ring drive nozzle is for generating a drive ring of air from the flow of compressed air and directing the drive ring of air onto the jet flow and the entrained air, and into an inlet of an exit expansion nozzle. |

1. An ejector for generating a vacuum comprising:
a first section comprising: a drive nozzle for generating a drive jet of air from a flow of compressed air and directing the drive jet of air into a first section expansion nozzle in order to entrain air in a volume surrounding the drive jet of air into a jet flow to generate a vacuum across the first section; and a ring drive nozzle for generating a drive ring of air from the flow of compressed air and directing the drive ring of air onto the jet flow and the entrained air, and into an inlet of an exit expansion nozzle. |
