Abstract
A nutating disc type fluid device in which in one embodiment nutating elements are mounting within a single chamber of a housing on a common shaft in a manner which is dynamically and pressure balanced. A divider plate is fitted through slots formed on one side of each nutating element so that relative rotation between the shaft and housing creates successive expanding and contracting volumes to draw fluid into the chamber through inlet ports and to exhaust fluid through outlet ports. The ports are sized and shaped to provide maximum and constant fluid flow. In another embodiment the nutating disc element is formed of an elastomeric material which permits unimpeded passage of solid objects that may be entrained in the fluid.
