Abstract
A gas/liquid mixture passes through a duct in which a filter device is interposed, the filter device being disposed such that its outlet duct is essentially vertical. The outlet duct opens out into a collecting enclosure placed above the filter device. A side outlet duct from the enclosure is disposed below the level of the liquid collected in the enclosure, a top portion collecting the gas given off above the level. The top portion communicates with the inlet of a jet which reinjects the gas into the outlet flow so as to form a homogeneous gas/liquid stream. The invention may be used, in particular, in the lubrication circuit of a vacuum pump having vanes and oil seals.
