  • Patent number: 7674101
    Abstract: The present invention provides a sliding vane, which is provided through a rotor in a cylinder and reciprocates in a diametrical direction and rotates together with the rotor. The sliding vane of the present invention includes a vane body (10), which has plate seating slots (23a) and (23b) formed in the respective diametrical opposite ends of the vane body. The sliding vane further includes two pairs of compression plates (3a) and (3b), (3c) and (3d), which are provided in the plate seating slots. First springs (15) are provided in a diametrically inner end of each compression plate. A sealing rod insertion slot (7a), (7b), (7c), (7d) is formed in a diametrically outer end of each compression plate, and a second spring (19) is provided between axially inner ends of the adjacent compression plates. The sliding vane further includes a sealing rod (5a), (5b) which is inserted into and occupies the entire length of the sealing rod insertion slots of adjacent compression plates placed in each plate seating slot.

  • Patent number: 7661940
    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.

  • Publication number: 20080264379
    Abstract: A rotary engine is disclosed. The rotary engine of the present invention includes an engine body (100), which has therein a compression chamber (101), an output chamber (105) and a combustion chamber (109, 115), which is formed between the compression chamber and the output chamber. The rotary engine further includes a compression rotor (400) which is eccentrically provided in the compression chamber, an ignition device (125, 126) which is provided in the combustion chamber of the engine body, and an output rotor (500), which is eccentrically provided in the output chamber. The rotary engine further includes valves (600) which are provided in the respective bores of the combustion chamber, a synchronizing means for rotating the compression rotor in conjunction with rotation of the output rotor, and an axial sealing means for sealing the compression chamber, the combustion chamber and the output chamber.

  • Patent number: 5697245
    Abstract: An outer-ring of a constant velocity joint is fabricated by pressing an inner surface of the pre-processed outer-ring (2A) set in a lower die (3) by using a forging punch (20) in which plural punch pieces (11) each having a protrusion (111) corresponding to the ball track groove (6) are slidably coupled to plural downwardly tapered grooves (131) of a punch piece slide member (13), so that an upper periphery (9A) of the pre-processed outer-ring (2A) is contracted in line with a head shape of the forging punch (20), and ascending the forging punch.
