Abstract
Abstract A piston type energy conversion machine such as an internal combustion engine in which the thrust of piston reciprocation is converted to nutational movement of a tube-like member journalled in a support which is driven in rotation about a primary engine axis. Also supported for rotation on the primary engine axis is a biconical element to which torque is transmitted by friction from the nutating member. The pistons operate in a plane which undergoes a swashing movement on a point at the intersection of the primary axis with the axis of nutation. Also the connection of the pistons to the nutating member is by way of linkage including swivel links which function to absorb the thrust of each piston power stroke.
