Abstract (en)

There is provided a scroll type compressor using lubricant oil and including a pair of scroll members (20, 30) confronting with each other in an axial direction. Each of the scroll members has an end plate (22, 32) extending perpendicular to the axial direction and an involute wall (21, 31) having a first and a second axial end which are opposite to each other in the axial direction. The first axial end is connected to the end plate. The second axial end confronts with the end plate of a counterpart one of the scroll members. In the scroll type compressor, the second axial end has a shallow groove (26, 36) with a depth for suitably holding therein the lubricant oil to form an oil seal between the second axial end and the end plate that confronts with the second axial end. <IMAGE>
