  • Energy transfer apparatus
    Patent number: 4387672
    Abstract: An apparatus having cylinders arranged radially about a rotatable shaft and a separate piston adapted to reciprocate in each cylinder. Each piston is held in contact with a cam eccentrically mounted on the shaft by means of linkages and rollers. The eccentrically mounted cam produces more complete scavenging of the cylinders and a large volume intake. The cam profile provides greater time for the power portion of the engine cycle than for the exhaust portion of the engine cycle. In a four-cycle apparatus, greater time also is provided for the intake portion of the cycle than for the compression portion of the cycle.
