ABSTRACT:
An expansible chamber energy conversion machine having a frame, a torque transmitting member supported by the frame for rotation about a first axis, a nutatable member having journal surfaces concentric with a second axis intersecting the first axis at an angle to establish a point of axes intersection, support means rotatable on the first axis and rotatably supporting the nutatable member for movement of the second axis in a biconical path about the first axis with the apex of the biconical path coincident with the point of axes intersection, one or more pistons reciprocable through a stroke distance in working fluid chambers having end faces fixed relative to the frame and adjustable linkage assemblies for connecting the pistons with the nutating member. The nutatable member is supported by the support means by way of a journal member arranged to change the angle of first and second axes intersection upon axial movement of the journal member relative to the support member. Static control means is provided for adjustably positioning the fulcrum point of a double-ended swivel link in a manner to shift the nutating member axially and thus change the nutational throw of the nutatable member in a manner to vary the stroke distance of piston reciprocation and maintain proper compression ratio. The nutatable member is driven by the pistons in a manner to convert piston reciprocation to rotary movement of the torque transmitting member.
