FIELD: engines and pumps. ^ SUBSTANCE: pump comprises housing made up of two intersecting cylinder parts 2, 3. Note here that inlet 4 and outlet 5 are arranged on opposite sides. Cylinders 2, 3 accommodate rotors 6, 7 to revolve about central lengthwise axis. Larger crosswise axes of said rotors run, at least in on phase, perpendicular to each other. Said rotors may roll over each other and relative to housing inner wall so that tightness is ensured. Generators originating from intersection of larger crosswise axes of every rotor in opposite directions extend inclined to adequate central lengthwise axis 8, 9. Every rotor surrounds two club-like parts with their narrow section connected together. Rotors 6, 7 feature configuration and relative arrangement to allow club0like section of one rotor to be engaged with taper of another rotor in case lather crosswise axes of both rotors are mutually perpendicular. Sine generators double as sealing lines. Openings 4 and 5 are shaped to triangle or trapezoid. Sides or lateral edges of said openings are shaped to sine or cosine. ^ EFFECT: higher efficiency. ^ 5 cl, 7 dwg |
