摘要： Scroll compressor, Oldham ring and a mating component for the scroll compressor.
The Oldham ring (20) for a scroll compressor (1), comprises: an annular body (21); andone or more keys (22a, 22b, 23a, 23b) protruding from the annular body (21) along an axial direction of the annular body (21), wherein the key (22a) is configured to be engaged with a corresponding sliding slot (16a) of a mating component (10) and has a contact root (33, 34) and a circumferential end surface (31, 32) to be engaged with the sliding slot (16a) whereby at least one of the keys (22a, 22b, 23a, 23b) is provided with a hollow portion (26a, 26a', 26a", 26a"') located at the contact root (33, 34), and an engagement wall (35, 36) with a predetermined stiffness and being elastically deformable is formed between the hollow portion (26a, 26a', 26a", 26a"') and the circumferential end surface (31, 32).

摘要： A scroll compressor is disclosed. The scroll compressor may include an anti-rotation mechanism provided with an anti-rotation pin (171) and an anti-rotation ring (172) between an orbiting scroll (130) and a scroll support member facing the orbiting scroll, and an axial thickness of the ring body portion (1721) constituting the anti-rotation ring may be larger than an axial depth of a ring insertion groove (1311) in which the anti-rotation ring is inserted. This can allow the orbiting scroll and a member facing the same to be spaced physically apart without a separate member, to secure a gap for oil to flow, such that the oil can be smoothly supplied between the orbiting scroll and the member, thereby suppressing seizure or/and friction loss between the orbiting scroll and the member.
