Abstract
An orbiting rotary compressor assembly having a compression mechanism disposed in a housing and including relatively moving fixed and orbiting compression members including extending portions having surfaces engaged with each other and between which a compression chamber is located. The orbiting member has a centrally-located hub which moves eccentrically relative to the axis of rotation of a drive shaft in driving engagement with the hub. A vane operatively engages the fixed member extending portion and the orbiting member extending portion, and partially defines the compression chamber. An Oldham coupling is disposed about and is in engagement with the hub, and is in engagement with the fixed compression member, rotation of the orbiting compression member being prevented by the Oldham coupling.
