Abstract: The present invention is for a means for transmission of force whereby linear movement is transferred into rotating movement or reverse. The invention is primarily intended to be used by combustion engines. The invention is for a means to transmit force between a forward and backward movement and a rotating movement by means of a ballbearing which runs in several tracks comprising a ball which is surrounded by ballholder which is fixed onto a piston rod for each respective ball or corresponding device for transmission of the linear movement. Fixed connected to each piston (4,5) is a piston rod (6,7) which in its opposite end has a holding device (17,18) for the ball (15,16) through which the force from the forward and backward movement is transmitted to the rotating disc (13). The balls (15,16) also serve as bearing between the stationary disc (8) and the rotating disc (13).

A secondary spring cushioned cam enables smooth transition of the piston follower rollers from an abrupt drop-off point on the main cam to a rotor torque inducing face thereof at the explosion point for each cylinder. Four cycle piston engine operation is achieved without the massiveness of a conventional fixed block piston engine of comparable displacement. The engine can be fuel injected or carburetor operated. Extreme simplicity of construction is achieved.

In a four-cycle engine, greater time also is provided for the intake portion of the cycle than for the compression portion of the cycle.

Abstract: Constant volume, continuous external combustion rotary engine which incorporates at least one radial piston compressor, at least one continuous-combustion chamber, at least one radial piston expander together with a means to supply fuel to the combustion chamber. A novel arrangement of compressor and expander manifolding controls admission and discharge to and from the compressor and expander sections. Power output is realized when opposed expander pistons equipped with roller bearings react directly on the internal cam lobe surfaces of a stationary housing causing the cylinder block to rotate and drive the compressor piston inwardly or outwardly as their roller followers engage their cam tracks. As a fresh charge of compressed air is delivered to the hydrocarbon fueled combustion chamber, an equal amount of combustion product under almost equal pressure is withdrawn by the expander. When combustion charging is completed, both compressor and expander are momentarily disconnected from the combustion chamber.

The surrounding right circular cylinder rotates as a result of the linear movement of the opposed pistons thereby providing mechanical power. The cam surface is a continuous track which determines the out-put motion of the piston movement between top and bottom dead center. Arcuate areas at top and/or bottom dead center permit constant volume combustion and/or exhaust as desired during a particular cycle, whether that cycle be Otto or Diesel and whether it be two or four stroke.
