Abstract: A scroll compressor having a sealed-oil interception structure, comprising: a partition plate unit which has an orifice, and a first sealing surface located at a bottom side of the partition plate unit and surrounding the orifice; a sealing assembly which is arranged below the partition plate unit and comprises a second sealing surface configured to surround a center hole of the sealing assembly, wherein the second sealing surface abuts against the first sealing surface to form a seal that separates a high-pressure side from a low-pressure side; and an oil interception device provided at the orifice of the partition plate unit. The present compressor may re-introduce a part of lubricating oil to an inner part of a scroll and/or to a low-pressure oil pool side, thereby improving the compression performance and operating stability of the compressor, and reducing the oil circulation rate.

Abstract: An oil supply mechanism comprises: an oil pump device connected to a rotating shaft of a rotating machinery; a main oil supply passage formed in the rotating shaft substantially in the axial direction of the rotating shaft; and a bypass oil passage in communication with the main oil supply passage and allowing a part of lubricating oil in the main oil supply passage to flow out via the bypass oil passage. The bypass oil passage extends in a direction substantially transverse to the rotating shaft. The bypass oil passage is configured such that a radial distance from an outlet of the bypass oil passage to the axis of the rotating shaft is greater than the radius of the rotating shaft.
