Abstract (en)

[origin: EP0825335A1] The system has at least two almost parallel outlet channels (19,20), the spacing (a) of which is less than twice the diameter of the larger channel. The diameter (d) of the outlet channels is between 0.8 mm to 1.5 mm, and approximately 1.2 mm, and the spacing of the channels about 1.5 mm. The diameter of the channels may be the same. On their inlet ends (21,22) the outlet channels are opened out in conical fashion, with a cone angle of about 45 degrees.
