TWO-STAGE ROTOR APPARATUS Russian patent published in 2010 - IPC B06B1/00 

FIELD: engines and pumps.

SUBSTANCE: two-stage rotor apparatus comprises tight casing, pipeline to feed fluid from delivery pump, stator and rotor with channels with two-row arrangement, cylindrical intake chamber and face intake chamber. There are gals between stator and rotor, made along cylindrical and face mating surfaces. First row of channels is formed on cylindrical rotor surface, while second row is arranged on face rotor surface. Note here that total flow section area of the first row is selected to be smaller than that of second row. Channels with different cross sections in rotor are angle-shifted, while those in stator are communicated with different liquid intake chambers.

EFFECT: higher dispersion in processed fluid flow.
