Abstract
A scroll compressor includes a fixed scroll compressor body and a moveable scroll compressor body that are arranged for relative orbital movement relative to one another to facilitate compression of refrigerant. The scroll compressor includes a key coupling acting upon the moveable scroll compressor body. The key coupling includes a ring body with a plurality of keys, with key contact surfaces, each of the keys projecting axially from the ring body. The key coupling includes four keys in separate quadrants defined by perpendicular lateral axes. The key coupling guides orbital movement of the moveable scroll compressor body along a linear translational path along a lateral axis.
