Abstract
A scroll compressor includes a housing having therein a discharge pressure region, a compression pressure region and a suction pressure region; a fixed scroll to form a discharge chamber as the discharge pressure region; and a movable scroll cooperating with the fixed scroll to form a compression chamber as the compression pressure region. The discharge pressure region includes an oil separation chamber connected to at least one of the compression pressure region and the suction pressure region through an oil supply passage having a flow restrictor. The flow restrictor is provided by a gap between an oil supply hole formed in the fixed scroll and an insertion member inserted in the oil supply hole. The gap is in the form of a spiral groove provided in at least one of an inner peripheral surface of the oil supply hole and an outer peripheral surface of the insertion member.
