Abstract

PURPOSE:To prevent lowering of the volumetric efficiency of a scroll compressor due to leakage of gas, by improving the sealing performance at sliding parts by forming an annular groove in the sliding surface of a fixed and a turning scrolls and disposing a magnet at the bottom of said groove with magnetic fluid being carried on the magnet. CONSTITUTION:When a crank shaft 4 is set into rotation along with rotation of a rotor 3a, a turning scroll 6 is turned by an eccentric shaft 4a and a turning mechanism 14. This causes change in the volume of a space defined between the turning scroll 6 and a fixed scroll 7, so that gas introduced from an inlet pipe 19 is compressed and discharged to an outlet pipe 10. Here, since pressure in an intermediate pressure chamber 16 is kept equal to that in a compression chamber 18 by the function of a connecting port 17, the above two scrolls 6, 7 are brought into sliding contact with each other. In the above arrangement, an annular groove 21 is formed at the sliding surface of one scroll 7 and a magnet 22 id disposed at the bottom of the groove 21 with a magnetic fluid 23 being carried on the magnet 22, so that it is enabled to prevent leakage of gas from the sliding parts of the two scrolls 6, 7.
