Abstract

A scroll compressor and a method for oil enrichment and distribution, wherein the scroll compressor includes a compressor housing, two scrolls, a respective base plate, an eccentric drive, a drive shaft, an axis of rotation, a balance weight, a first bearing, a second bearing, and a counter-pressure space, and wherein a sealing washer is fixed on the first bearing at a side of the first bearing directed to the cavity of the rotatable balance weight and of the second bearing such that the sealing washer seals the first bearing on one side in a radially outer part of a region between an inner ring and an outer ring through which fluid can flow and is, at the same time, spaced from the inner ring in a radial manner such that a gap through which fluid can flow remains.
