Abstract
A scroll compressor includes an orbiting bedplate which has an oil passage through which oil flows outward in a radial direction of the orbiting bedplate, a lap-side oil supply hole that causes the oil passage to communicate with a lap-formation surface of the orbiting lap, and a thrust-surface-side oil supply hole that causes the oil passage to communicate with a thrust surface of the orbiting bedplate that is opposite to the lap-formation surface of the orbiting bedplate. An opening and closing mechanism provided in the oil passage closes the thrust-surface-side oil supply hole when the pressure of oil that is drawn from an oil sump by an oil pump and supplied into the oil passage is low, and opens the thrust-surface-side oil supply hole when the pressure of the oil is high.
