Abstract

A scroll-type machine is disclosed which incorporates a unique Oldham coupling for preventing relative rotation between the two scroll members while allowing relative orbital motion therebetween. The Oldham coupling is positioned below the end plate of the orbiting scroll member and includes a first pair of keys slidingly engaging slots in the orbiting scroll and a second pair of keys slidingly engaging slots in the non-orbiting scroll. An optional third key may be provided to slidingly engage a slot in the non-rotating bearing housing.
