Abstract

A rotary power device comprising a stationary block; at least one cylinder defining a cylinder axis formed in the block; a piston slideably supported in the cylinder; a cylindrical crankshaft arranged to rotate about a crankshaft axis which is parallel to the cylinder axis; and a connecting rod attached at a first end to the piston and coupled at a second end to the crankshaft by at least one piston bearing; wherein the crankshaft comprises a curved annular track defining first and second axially spaced bearing surfaces for engagement with the piston bearing.
