Abstract (en)

[origin: EP1790931A2] The arrangement has a low pressure side arranged in a radial direction near a central longitudinal axis than a high pressure side. A free flow section of the high pressure side is altogether smaller than a free flow section of the low pressure side. Inflow openings are provided for two mediums, where the inflow openings are arranged on different sides of the arrangement. An outer tube (5) of the arrangement is divided maximally into sixteen partial channels, where an inner tube (3) exhibits a small wall thickness.
