Abstract
A scroll compressor includes a stationary scroll; an orbiting scroll having a pair of first Oldham keyways on one surface thereof, the orbiting scroll defining a compression chamber in combination with the stationary scroll; a frame having a pair of second Oldham keyways and supporting the orbiting scroll; and an Oldham ring for inhibiting rotation of the orbiting scroll, the Oldham ring having a pair of first Oldham keys on one surface thereof and a pair of second Oldham keys on the other surface thereof, the first Oldham keys slidably engaging with the respective first Oldham keyways, the second Oldham keys slidably engaging with the respective second Oldham keyways. The Oldham ring includes at least a pair of projections on the other surface thereof, and the projections have a height such that when the Oldham ring is inclined during simple harmonic motion, one of the projections makes contact with the one surface of the orbiting scroll before each of the first Oldham keys is brought into contact with the corresponding first Oldham keyway at two locations.
