CONSTITUTION: A scroll compressor(50) comprises: a compression device(2) which includes a fixed scroll(3) and a rolling scroll(4) which is movable to the axial direction towards the fixed scroll in the inside of a sealed container(1); a motor which drives the rolling scroll through a crank shaft(6); and an oil supply member wherein a thrust ring(30) is installed on the rear end of the rolling scroll, a ring backpressure room(20) is installed on the rear end of the thrust ring, and an oil storage(10) which stores lubricating oil is installed in the internal space of the sealed container and which supplies the lubricating oil of the oil storage by the rotation of the crank shaft. The lubricating oil which is supplied from the oil supply member pressurizes the thrust ring by being induced to the ring backpressure room. |
