ABSTRACT:
A spherically-shaped piston is rigidly attached to a connecting rod for reciprocating and tilting motion within a borehole in response to rotation of a crankshaft having an associated crank which is rotatably attached to the connecting rod. Web and ribs and ridges integrally formed on the hollow, undeside of the piston control thermal transfer and deformation to assure continuous perimeter seal with the walls of the borehole over all operating temperatures as the piston sides and tilts within the borehole.
