FIELD: machine building.SUBSTANCE: invention relates to machine building. The rotary machine includes the work stage. The work stage contains casing with branches and rotor installed in it on the shaft with possibility of rotation. The rotor has spiral multilobe wok channels. The work channels are tightly closed by casing and by the rotating shutters located perpendicular to the rotor. Stage on the shaft are secured by pairs with location in centre of HP or vacuum zone. The shutters are made flexible out of packages of the resilient heat resisting sheets with antifriction wearproof coatings or gaskets.EFFECT: increased productivity and power, simple design of the machine, and assurance of axial forces compensation.7 cl, 8 dwg |
