Abstract
A rotary engine includes a cylinder within a housing accommodating a pair of reciprocating pistons. A drive shaft extends from the cylinder to provide output power when rotated with the cylinder. A linkage attached to the top of each piston is connected to the driveshaft to translate the reciprocal motion of the piston to the rotational movement of the cylinder. An extension of the linkage fits within a cam surface in the end wall of the housing. The linkage can take one of several embodiments. The linkages have channels for distributing oil throughout the housing. Each piston face may have a central depression with a spiral channel leading from the edge of the piston to the depression.
