ABSTRACT:
A rotor for rotary engines and compressors is disclosed. The rotor of the present invention includes a first body unit (100a), which has a rotor housing (102) and a core (104) provided with a plurality of roller plate seats. The rotor further includes a second body unit (100b) having a structure symmetrical with the first body unit, a roller support plate (40), which is placed on each of the roller plate seats, a roller cage (42), which is provided on each of the roller support plates and has a pin roller receiving space therein, and a plurality of pin rollers (46), which are placed in the pin roller receiving space of the roller cage to ensure smooth reciprocation of the sliding vane. The rotor further includes the sliding vane (30), which is provided between the first body unit and the second body unit and reciprocates in a diametrical direction, and a spacer (106), which maintains a constant distance between the first body unit and the second body unit.
