Scroll compressor and refrigeration cycle apparatus

Abstract

A scroll compressor includes a crank shaft, an orbiting scroll, and a frame. The crank shaft has a lubricant channel allowing lubricant to flow through the lubricant channel. The orbiting scroll is attached to the crank shaft and includes a base plate that is discoidal. The frame has a thrust surface against which the orbiting scroll slides. The thrust surface has an annular shape and faces an outer circumferential region of one surface of the base plate of the orbiting scroll. 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 in the outer circumferential region of the one surface of the base plate facing the thrust surface 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.
