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).

Abstract: An internal combustion rotary engine with multiple cylinders and rotary crankcase supported on a pair of engine stub shafts. The connecting rods are each connected to a different center arranged evenly around the drive center of a stepdrive element. The stepdrive element which is polygonal or circular is offset from the rotational axis of the crankcase within which it revolves. The stepdrive element drives the crankcase through a series of links. As each piston fires the connecting rod is inclined to the piston travel axis and the angle between the connecting rod and the stepdrive element center is close to 90 degrees. As the piston moves through its power stroke the cylinder rotates with the crankcase maintaining the mechanically advantageous 90 degree angle for about 100 degrees of crankcase rotation. Symmetric and asymmetric cylinder layouts, Diesel and 2-stroke layouts are disclosed.

The rotary frame carries three crankshafts at substantially 120.degree. intervals, and for each crankshaft there is provided a cylinder in the rotary frame, and a piston mounted for reciprocation in each cylinder. Each crankshaft is fixed to rotate with a respective planetary gear and all planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear. Thus, any point on the pitch circle of a planetary gear describes a cardioid as the planetary gear rotates around the sun gear once. The crankshaft eccentricity is about one-third of the pitch radius of a planetary gear, and each piston has a connecting link to its respective crankshaft. Fuel metering means, such as a carburetor, are provided for delivering a combustible mixture to the cylinders.

Abstract: A pump supplies pressurized lubricant to an internal combustion engine from an external reservoir through a closed loop system. Delivery channels extending through the crankshaft, connecting rod and other components, supply the pressurized lubricant to the several areas of relative movement. Return channels, extending through the components, conduct lubricant from the several areas to the reservoir. Fuel-air mixture from a carburetor enters the crankcase through the open end of the crankshaft and moves through ports within the several cylinders to the respective combustion chambers. Selected ports are sequentially closed by a valve plate carried by the crankshaft. Incomplete products of combustion are exhausted into an auxiliary exhaust outlet for recycling with the fuel-air mixture. Retainer members engaging the spark plugs assist in dissipating heat therefrom.
