Abstract (en)
[origin: EP1288504A1] The vacuum production device (1) incorporates at least one ejector device (3), which has a radiation nozzle (5) followed by a catchment nozzle (6) and in the transition area between the radiation nozzle and the catchment nozzle has a defined suction zone (21). At the outlet side end of the catchment nozzle a catchment space (23) is provided for the fluid flowing through the catchment nozzle. From this space emerges an outflow channel (24). Devices are provided for influencing the fluid flow through the outflow channel. The outflow channel nominal diameter (dA) at the position of the narrowest cross-section of the outflow channel is greater than the radiation nozzle channel nominal (7) diameter (dS) and is smaller than the catchment nozzle channel nominal diameter (dF) measured at the position of the narrowest cross-section of the catchment nozzle channel.
