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.

Abstract: A scroll compressor includes an orbiting bedplate. The orbiting bedplate has: an oil passage through which oil supplied from an oil supply passage 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 at which the orbiting lap is formed; 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. In the oil passage, an opening and closing mechanism is provided. The opening and closing mechanism 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.

Abstract: A scroll compressor includes an orbiting scroll including an end plate and a spiral element on the end plate, a fixed scroll including an end plate and a spiral element on the end plate, and an Oldham ring including a support. The scroll compressor satisfies a relation of ?1>?2, where ?1 denotes each of the axial length of a gap between the tip of the spiral element of the orbiting scroll and the end plate of the fixed scroll and a gap between the tip of the spiral element of the fixed scroll and the end plate of the orbiting scroll, and ?2 denotes the axial length of a gap between the end plate of the orbiting scroll and the support of the Oldham ring.
