Abstract (en)
[origin: EP3575605A1] In a hermetic compressor of the present invention, a rotation shaft oil support hole 13c is formed in a rotation shaft 13, a lower end 13b of the rotation shaft 13 includes an oil groove 13f and a lateral hole 13g, a plate-side oil passage 42 is formed in a thrust-receiving plate 40, and a housing-side oil passage 51 is formed in an oil pump housing 50. At a location higher than the oil groove 13f, lubricant oil supplied from the lateral hole 13g moves downward in the oil groove 13f by bringing an upper portion of the sliding bearing 13e and the rotation shaft 13 into abutment against each other, and the lubricant oil in the oil groove 13f is discharged below the auxiliary bearing 18 through the plate-side oil passage 42 and the housing-side oil passage 51. According to this configuration, it is possible to prevent the lubricant oil from being discharged to the upper portion of the auxiliary bearing 18.
