SCROLL COMPRESSOR AND REFRIGERATING APPARATUS

Abstract: a scroll compressor includes a casing, and a compression mechanism housed in the casing. the compression mechanism includes a fixed scroll and an orbiting scroll. the fixed scroll includes a fixed end plate, an outer circumferential wall provided on an outer edge of the fixed end plate, and a spiral fixed wrap provided inside the outer circumferential wall. the orbiting scroll includes an orbiting end plate, and a spiral orbiting wrap provided on a front surface of the orbiting end plate. the outer circumferential wall has a facing surface that faces the front surface of the orbiting end plate. the facing surface has an oil groove to which a lubricant with a high pressure equivalent to a discharge pressure of the compression mechanism is supplied. the oil groove has a circumferential groove portion, and a radial groove portion extending radially outward and communicating with the circumferential groove portion.
