FIELD: mechanical engineering. SUBSTANCE: rotor machine has housing with a cylindrical bore and passageways for supplying and discharging fluid, stop ring axially alined in the housing, rotor with diametrical profiled grooves that is mounted inside the housing eccentrically, and rods received in the grooves. The ends of the rods are provided with separating plates that can move in radial direction inside the rotor grooves and define working chamber in the stator ring. Both of the rod ends are rigidly secured to the adjacent plates. The inner surface of the stator ring is a polyhedron. The polyhedron is coaxial to the outer surface of the stator ring. The number of sides of the polyhedron is equal to the number of the plates. The length of the sides is defined by a relationship available in the invention description. The contact surface of the radial end of the plate is perpendicular to the rod axis. The width of the contact surface of the radial end of the plate is greater than the thickness of the plate. A longitudinal groove is made in the central part of each contact surface of the plate. The groove receives a flexible sealing member. The member is a plate bent in the cross-section, e.g., as an arc of a circumference. The rotor and stator ring are kinematically interconnected through a gear with 1:1 gear ration. EFFECT: enhanced longevity. |
