LUBRICATION STRUCTURE OF SWASH PLATE TYPE COMPRESSOR

摘要

PURPOSE:To increase lubricity to prevent the rotation following the rotation of an outer ring of a thrust bearing and the pressurizing part of a cylinder block from being worn by eccentric oscillation. CONSTITUTION:The proper number of protrusions 22 are provided on a drive shaft 12 along the circumferential direction near the outside of an outer ring 14b of a thrust bearing 14 to introduce refrigerant gas which flows from a swash plate chamber 9 into a shaft hole 2a into a clearance between the outer ring 14b of the thrust bearing 14 and the pressure receiving part 2b of a cylinder block 2 by the protrusions 22 which are rotated together with the drive shaft 12 during the operation of a compressor.
