摘要

A mixing chamber (3) and a gas inlet chamber (5) are concentrically arranged in a closed housing (1) and mutually separated by a tubular partition (7) provided with micropores. A stream of liquid foamable medium is axially introduced by a pump (21) into the mixing chamber (3). At the same time, air compressed by a compressor (23) is introduced into the gas inlet chamber (5) through a housing inlet (17) under such a pressure that the air can penetrate into the mixing chamber (3) through the micropores of the tubular partition (7). The partition (7) that surrounds the mixing chamber and the circumferential wall (9) are interchangeably mounted between two flanges (11 and 12). The cross-sectional profile of axial inlets and outlets (15 and 16) is adapted to the cylindrical cross-section of the mixing chamber (3), so that during operation of the device a laminar stream of foaming mixture, essentially parallel to the axis of the chamber, flows through the mixing chamber (3).
