Abstract (en)
[origin: EP1803508A2] The vacuum creating device includes an ejector (26), the suction side of which is connected to a sealed cavity (12). The ejector is supplied with compressed air via a valve (38a). A sensor (42) is connected to a vacuum regulator (44) controlling the valve, which it opens if the sensor misses an excessive pressure in the sealed cavity.
