ROTARY-PLATE MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: rotor with slots is eccentrically mounted on a shaft in a body with inlet and outlet channels and end covers which has a profile bore. The slots are adjacent in pairs on part of the their length to form an overlap section of the slots in the middle part of the rotor, and have plates positioned inside. The plates are mounted for engagement with end covers and to form working chambers. The inlet channel is positioned opposite to the overlap section of the slots. The outlet sections are positioned on the side of the end covers. The rotor length is larger than that of each slot but smaller than the total length of two adjacent slots. The bore is made in the form of two hollow conical ovoidal geometrical bodies facing each other by smaller bases, and facing the end covers by the larger bases. The rotor is made in the form of two equally truncated cones facing each other by smaller bases, the slots are made trapezoidal and deepen into the shaft to a depth exceeding the value of the eccentricity. The plates are made in the form of an equilateral trapezoid which large bases face the end covers and their length exceeds the total value of the eccentricity and the rotor part extending above the shaft. The angles of conicity of the body bore, the rotor generatrix and the angle of between the slots and the longitudinal axis of the rotor are equal. EFFECT: improved structure. 5 dwg
