Abstract: The gas/liquid mixture passes through a pipe (3, 4) in which is interposed a filtering device (1) arranged so that its outlet pipe (8) is directed essentially vertically. This pipe (8) opens out into a collector enclosure (9) placed above the filtering device. A lateral outlet pipe (4) from this enclosure is located below the level (11) of the liquid gathered in the enclosure, an upper part (12) gathering the gases which opens out above this level (11). This upper part (12) communicates with the inlet to a nozzle (13) which reinjects the gas into the outlet flow, so as to form a homogeneous gas/liquid outflow. The invention can be used particularly in the lubrication circuit of a vacuum pump with vanes and oil seals.

Abstract: A positive-displacement machine comprising a piston situated in a casing. The outline of the piston is hypertrochoidal, as is the outline of the hollow inside volume of the casing. The piston has n axes of symmetry, and the casing has n+1 axes of symmetry. The piston rotates inside the casing in orbital motion about the axis DELTA c of the casing. To obtain the rotation in orbital motion, firstly the piston is freely rotatably mounted on a crank pin that has its axis offset relative to the axis of a supporting shaft that is coaxial with the axis DELTA c of the casing, the shaft being rotated, and secondly the surface of the piston and the surface of the hollow inside volume of the casing are equipped with permanent magnets creating magnetic repulsion forces.

Abstract: The machine comprises a cylindrical piston (1) of axis DELTA p, which is rotary and situated in a cylindrical capsule (5) of axis DELTA c, the piston (1) having a profile having Sp axes of symmetry, the said capsule (5) defining a hollow volume (4) of which the cross section through a plane perpendicular to its axis DELTA c, has Sc axes of symmetry, Sp and Sc being different from one another by one, the axes DELTA p and DELTA c, which are parallel, being separated by a distance E, the piston (1) and the capsule (5) delimiting between them at least three chambers (A, B, C) and the capsule including at least one suction inlet (9, 10, 11) and one delivery outlet (13, 14, 15) and the machine is characterised in that it comprises a ferromagnetic gear (2, 30) of axis DELTA p integral with the piston (1) and including Np teeth, located inside a ferromagnetic ring (6, 32) of axis DELTA c and integral with the capsule (5), the said ring being equipped with NB electric coils (20, 33) arranged radially, in that the ratio Np DIVIDED NB is equal to the ratio Sp DIVIDED Sc, and in that the NB electric coils (20, 33) of the said ring (6, 32) are powered in succession.
