Title: Rotary cam fluid working apparatus

Abstract

This patent describes an internal combustion engine comprising: a housing having housing walls which substantially enclose a housing interior including at least one intake passageway and at least one exhaust passageway through which one working fluid passes to and from the housing interior; a rotor mounted within the housing interior for rotation about a rotor axis of rotation extends longitudinally within the housing; the rotor has exterior surfaces which are substantially cylindrical about the rotor axis of rotation; the rotor further includes interior surfaces having cylindrically concave interior surface portions extending longitudinally within the rotor to define a rotor interior; having at least one rotor port communicating the rotor interior with the housing passageways to allow passage of a working fluid into and from the rotor interior; cam structures mounted substantially within the rotor for rotation with respect thereto; the cam structures including cam surfaces which are convex; exterior surfaces of the cam structures each include a major curvature surface which is at least partially defined by an associated major radius of curvature centered upon the associated axis of rotation of the cam structure; each major radius of curvature is greater than one-half of a separation distance existing between themore » associated axis of rotation of the cam structure and adjacent axes of rotation of adjacent cam structures; and cam synchronizing means for maintaining structures in approximately parallel relative angular orientations with respect to the housing as the rotor rotates and the cam structures revolve about each other.« less
