VORTEX EJECTOR Russian patent published in 2015 - IPC F04F5/16 

FIELD: machine building.

SUBSTANCE: vortex ejector contains a casing with tangential output and input radial and axial branches. The casing is made in form of input and output coaxial cylindrical parts. Inside the input part the internal cylindrical casing is coaxially installed with axial input branch, being simultaneously dead-end axial branch for the input part of the casing, and axial output coinciding with output end of the input part of the casing. In the ring space between the casing of the input part and internal casing the dual-entry spiral channel is made with start from radial input branch in the direct vicinity of the axial input branch, and with end by 15±5 mm from output end of the internal casing. In the output part of the casing abutting to the input part a ring diffuser is made, it is created by internal hull lines and fairing build-in coaxially with casing. The output branch located tangentially near end of output part of the casing outermost from input part is made in from of diffuser.

EFFECT: increased efficiency of icing prevention of elements of input channel of gas transfer unit.
