PROBLEM TO BE SOLVED: To effectively feed lubrication oil to the pressure surface of a slicler during a compression process, in a scotch yoke type hermetic motor-driven compressor. SOLUTION: A slider 8 is reciprocated in a slide pipe 10b, formed integrally with a piston 10, since an eccentric part 6a in which a slider 6a is rotatably fitted is eccentrically rotated. A crank pin branch hole 6d extending through an inner surface to an outer surface is formed in the eccentric part 6a and this constitution feeds lubrication oil to the inner surface of the fitin hole of the eccentric part 6a of the slider 8 from the interior of the eccentric part 6a. Further, a slider oil feed hole 8c extending through the fit-in hole of the slider 8 to an outer peripheral part 8b. When the slider oil feed hole is connected to a crank pin branch hole 6d, lubrication oil is fed to the outer surface part 8b of the slider 8 from the interior of the eccentric part 6a. An opening at the slider oil feed hole 8c and on the outer peripheral surface 8b side of the slider 8 is set to a position in the vicinity of a part making contact with a slide pipe 10b making contact with a slide pipe 10b during the compression stroke of the outer peripheral surface 8b of the slider 8. |
