Title:
SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP3031297
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the oil feed performance by providing a driving shaft having an eccentric pin part and giving the driving force to a scroll type compressing element, with a fluid passage and an oil feed passage separated from each other along the axial direction, and covering an opening edge at a slide bush side of the oil feed passage with the slide bush.
SOLUTION: When a crankshaft 4 is rotated and driven, a movable scroll 5 is revolved to a fixed scroll, and the compressed coolant gas is discharged from a discharge opening 5d. The coolant gas is discharged through a discharge gas passage 4b of the crankshaft 4. During this time, the oil is pumped up from an oil reservoir of a bottom part of a casing 1 through an oil feed passage 4a, by the centrifugal force by the rotation of the crankshaft 4. The oil reaching the opening edge of the oil feed passage 4a, is filled in the total periphery of an oil pool part 20b formed on a slide bush 20, and is elevated upward in a gap between the slide bush 20 and a drive pin 4c in the total periphery, to be supplied to a sliding face between the slide such 20 and a bearing part 22.
