ROTOR AXIAL DEVICE Russian patent published in 2014 - IPC F04C2/356 F04C9/00 

FIELD: machine building.

SUBSTANCE: rotor axial device used as a pump comprises a casing with a cylindrical cavity in it, two cylindrical rotors with outer contact surfaces rotating in it and fixed at one shaft, one central disk, one damper baffle, suction and outlet channels made in the shaft, inlet and outlet holes. The disk is located between the rotors. The baffle is installed so that it can move between the outer contact surfaces of the rotors. The inlet and outlet holes are made on the opposite flat surfaces of the central disk on both sides of the damper baffle. The distance between the outer contact surfaces of the rotors is equal to the length of the damper baffle at all angles of simultaneous rotation of rotors in respect to the axis of the rotor axial device.

EFFECT: provision for design with no breaks in the processes of separate suction and pressing-out of working medium at all rotors' positions.
