Abstract (en)
[origin: EP1213485A2] The vacuum creating device has two ejector devices (2, 2'). An operating fluid is stored in the first one, creating a negative pressure at an induction aperture (16) connected to the output aperture (15') of the second ejector device, and thus forming an outflow affecting the induction aperture (16') of the second injector device.
