Abstract (en)
[origin: EP1876357A1] Disclosed herein is an oil supply structure of a scroll compressor. The oil supply structure is provided to prevent a slender hole of an oil supply screw (24) from being clogged with sludge, the oil supply screw being provided between a backpressure space, which is defined between an orbiting scroll and a main frame, and a space which is defined between a fixed scroll and the main frame, and adapted to supply oil from the backpressure space into the space. The oil supply screw includes an orifice having a center hole (28) longitudinally perforated through the center of an upper portion of a screw body of the oil supply screw and a slender hole (29) continuously perforated below the center hole to have the same axis as that of the center hole, and a sludge discharger (30) having a non-flat- plane configuration and formed at a lower entrance end of the screw body.
