ROTOR MACHINE OF MULTIPLE ACTION Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: stator plates are placed in its slots made with an angular step. A coaxially set up rotor with protrusions contacts with the face covers and plates. Inlet and outlet windows are located between the protrusions. The number of plates is equal to the double number of protrusions increased by a unit. The central angle limiting every bridge between the windows is equal to that between the plates. The sum of the central angles limiting each window in the rotor is equal to the central angle between the plates located in the cover slots. EFFECT: facilitated manufacture. 2 cl, 4 dwg
