More Information
Summary:The present disclosure relates to a scroll compressor and its lubricating oil supply system. The lubricating oil supply system includes: an oil passage P1 formed by a core hole extending longitudinally through the crankshaft; an oil pump, whose oil suction port is immersed in the lubricating oil in the oil pool, and the oil outlet is connected to the oil circuit P1; an oil passage P3 located in the gap between the upper end surface of the crankshaft and the lower surface of the orbiting scroll; an oil passage P4 formed by a longitudinal hole in the crankshaft, the longitudinal hole extending downwards from the upper end surface of the crankshaft; an oil passage P5 formed by a transverse hole in the crankshaft and a gap between the lower edge of the hub of the orbiting scroll and the upper surface of the upper counterweight, the transverse hole extending transversely from the outer peripheral surface of the upper end of the crankshaft to communicate with the longitudinal hole, the opening of the transverse hole on the outer peripheral surface of the upper end of the crankshaft is aligned with the gap between the lower edge of the hub and the upper surface of the upper counterweight; an oil passage P6 formed by the gap between the outer peripheral surface of the hub and the upright wall of the upper counterweight, and the gap between the outer peripheral surface of the hub and the inner peripheral surface of the center hole of the housing; and an oil passage P2 formed by an oil return pipe so that the lubricating oil circulates.
