Abstract (en)

[origin: EP1747815A1] The device has a supply conduit (1) that is open at its ends in which one end is connected to an inlet (301) of a pumping chamber. A part of the conduit circulates below the level of a foaming liquid (10). The conduit is connected at the ends by keeping absolute separation between the interior and exterior of the conduit, except for a suction hole (103). The hole is provided in the conduit below the liquid level (11). The size of the hole is such that the liquid does not circulate via the hole, except during circulation of air in the conduit, at a speed greater than a preset speed.
