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.

The invention claimed is: 1. A rotor, comprising: a first body unit, comprising: a rotor housing having a hollow semi-cylindrical shape; a core having a solid semi cylindrical shape and provided in the rotor housing, with a plurality of roller plate seats formed by depressing opposite sides of a pl
The invention claimed is: 1. A rotor, comprising: a first body unit, comprising: a rotor housing having a hollow semi-cylindrical shape; a core having a solid semi cylindrical shape and provided in the rotor housing, with a plurality of roller plate seats formed by depressing opposite sides of a planar surface of the core based on a partition wall axially provided on the planar surface of the core; a second body unit having a structure symmetrical with the first body unit; a roller support plate placed on each of the roller plate seats of the first and second body units and having a size corresponding to an area of the roller plate seat, with a stopper provided on each of axial opposite ends of the roller support plate; a roller cage provided between the stoppers of each of the roller support plates, with a pin roller receiving space formed through the roller cage; a plurality of pin rollers, each having a cylindrical shape in which a diameter thereof is less than a length thereof, the pin rollers being placed in the pin roller receiving space of the roller cage at positions adjacent to each other, so that, when a sliding vane reciprocates in a diametrical direction, the pin rollers roll between the roller support plate and the sliding vane; the sliding vane provided between the pin rollers of the first body unit and the pin rollers of the second body unit and reciprocating in the diametrical direction, with a spacer hole formed at a central position through the sliding vane and extending a predetermined length in the diametrical direction; and a spacer inserted into the spacer hole of the sliding vane and maintaining a distance between the first body unit and the second body unit. 2. The rotor according to claim 1, wherein a plurality of sealing rod insertion slots, each of which extends in an axial direction and has a predetermined depth towards a central axis of the first and second body units, is formed in a circumferential outer surface of each of the first and second body units, a plurality of pneumatic pressure guide holes is formed in the circumferential outer surface of each of the first and second body units, such that each of the pneumatic pressure guide holes extends from a position defined adjacent to a corresponding sealing rod insertion, slot on a circumferential outer surface of each of the first and second body units, to a bottom of each sealing rod insertion slot, so that high-pressure gas in a cylinder, in which the rotor is placed, is supplied into the bottoms of the sealing rod insertion slots through the pneumatic pressure guide holes, and a sealing rod is inserted into each of the sealing rod insertion slots and comprises: two rod pieces, with a spring insertion hole and an insertion notch formed in each of the rod pieces, and a first spring and a pressure leakage prevention member respectively inserted into the spring insertion hole and the insertion notch, so that high-pressure gas, which is supplied into the bottom of the related sealing rod insertion slot through the pneumatic pressure guide hole, pushes the sealing rod towards an inner surface of the cylinder while the pressure leakage prevention members prevent the high-pressure gas from leaking in the axial direction; and a second spring provided between the rod pieces of the sealing rod, thus pushing the rod pieces in axially opposite directions. 3. The rotor according to claim 1, wherein a sealing rail seating groove is axially formed in each of junction surfaces of the rotor housings of the first and second body units between the rotor housings and the sliding vane, a sealing rail is inserted into the rail seating groove, and a third spring is placed inside the sealing rail to push the sealing rail towards the sliding vane. 4. The rotor according to claim 1, wherein a sealing member insertion notch, having a predetermined axial depth, is formed at a position defined adjacent to each sealing rod insertion slot in semicircular edges of opposite ends of the first and second body units, a sealing member is inserted into the sealing member insertion notch, a fourth spring is provided in the sealing member, and a pneumatic pressure guide groove is formed in a side surface of the sealing member insertion notch such that high-pressure gas is drawn into the sealing member insertion notch through the pneumatic pressure guide groove, so that the sealing member is biased axially outwards both by the fourth spring and by the high-pressure gas.
