Abstract
A scroll compressor includes an orbiting scroll including an end plate and a spiral element on the end plate, a fixed scroll including an end plate and a spiral element on the end plate, and an Oldham ring including a support. The scroll compressor satisfies a relation of δ1>δ2, where δ1 denotes each of the axial length of a gap between the tip of the spiral element of the orbiting scroll and the end plate of the fixed scroll and a gap between the tip of the spiral element of the fixed scroll and the end plate of the orbiting scroll, and δ2 denotes the axial length of a gap between the end plate of the orbiting scroll and the support of the Oldham ring.
Claims8
A scroll compressor, comprising:
- a fixed scroll including an end plate and a spiral element on the end plate;
- an orbiting scroll including an end plate and a spiral element on the end plate of the orbiting scroll, the spiral element of the orbiting scroll engaging with the spiral element of the fixed scroll to define a compression chamber;
- a crankshaft configured to drive the orbiting scroll;
- a frame supporting the orbiting scroll across the orbiting scroll from the fixed scroll;
- and
- an Oldham ring disposed between the end plate of the orbiting scroll and the frame, the Oldham ring being configured to prevent the orbiting scroll from rotating to allow the orbiting scroll to orbit against the fixed scroll,
- the Oldham ring including a ring portion that is annular, a surface of the ring portion facing the end plate of the orbiting scroll including a support to contact the orbiting scroll when the orbiting scroll tilts during an orbiting motion of the orbiting scroll,
- the scroll compressor satisfying a relation of δ1>δ2, where δ1 denotes an axial length of each of a gap between a tip of the spiral element of the orbiting scroll and the end plate of the fixed scroll and a gap between a tip of the spiral element of the fixed scroll and the end plate of the orbiting scroll, and δ2 denotes an axial length of a gap between the end plate of the orbiting scroll and the support of the Oldham ring.
