Abstract
A scroll compressor includes a crank shaft, an orbiting scroll, and a frame. The crank shaft has a lubricant channel. The orbiting scroll has an inner channel and a lubricant channel groove. The inner channel allows the lubricant supplied through the crank shaft to flow outward. The lubricant channel groove has an annular shape and allows the lubricant supplied through the inner channel to be supplied to the thrust surface. The lubricant channel groove is formed such that the lubricant channel groove stays within a region of the thrust surface while the orbiting scroll is orbiting.
