Patent number: 4648358Abstract: An internal combustion engine having two rotating cylinder blocks in each of which is formed a plurality of cylinders to receive portions of pistons that extend partially into each cylinder block. The cylinder blocks are angled relative to one another and the pistons are similarly angled to cause variation in the free volumes of the cylinders as the cylinder blocks rotate. A support shaft passes through the centers of the cylinder blocks to provide support for the cylinder blocks via bearings on the support shaft. Air is introduced into the cylinders via central cavities in the cylinder blocks and fins and slots are formed on, and in, respectively, the interior walls of the cavities to impart rotation to air in the cavities. A series of rings, through which the cylinders pass, are formed on the end of each cylinder block that faces away from the other cylinder block to circulate cooling air drawn into a housing in which the blocks are mounted about the cylinders.Type: GrantFiled: July 22, 1985Date of Patent: March 10, 1987Assignee: Sullivan Engine Works, Inc.Inventors: Robert W.
