ABSTRACT:
The present invention is a nutating positive displacement device including a nutator with an inverted pendulous, low friction, substantially non sliding vertically elongated double pivoting nutator fulcrum. The fulcrum is one member comprising a bottom base coupled to a central beam coupled to a top nutator support bearing surface. The bottom of the fulcrum comprises a pivoting base pivotally and substantially non slidably mating with a base receptacle defined by a body interior surface. The base is coupled to the fulcrum beam which in turn supports the fulcrum nutator support bearing surface. The nutator support bearing surface pivotally and substantially non slidably mates with a nutator restraint defined by the center bottom surface of the nutator.
