SCROLL COMPRESSOR

PROBLEM TO BE SOLVED: To obtain a scroll compressor capable of preventing refrigerant leakage from a clearance of the side face of teeth of a fixed scroll and an oscillating scroll.SOLUTION: A scroll compressor 100 comprises a fixed scroll 1, an oscillating scroll 2, an Oldham mechanism 9, a compliance frame 3, a shaft 4 fixed to an electric motor rotor 8, a boss part 2d of the oscillating scroll 2, an oscillating bearing 2h formed on the inside surface of the boss part 2d, and a slider 12 disposed between the oscillating bearing 2h and the shaft 4 for transmitting the torque of the shaft 4 to the oscillating scroll 2. The pressure inside the boss part internal space 2g of the oscillating scroll 2 at a high pressure is reduced by the oscillating bearing 2h. An intermediate pressure chamber is formed at the rear surface of the oscillating scroll 2. An oscillating spiral teeth 2b are pressed against fixed spiral teeth 1b by the intermediate pressure and the teeth side surfaces of the oscillating spiral teeth 2b are pressed against the teeth side surfaces of the fixed spiral teeth 1b by the slider 12.
