Abstract
A crank drive mechanism for the two-piston Stirling engine which reduces engine size, cost and complexity, while increasing mechanical efficiency. A single throw crankshaft is located in a housing below two cylinders. A triangular yoke connects the single crankpin with two guided pistons which operate in these cylinders. A rocking lever connects the yoke with the engine housing and absorbs any side loads associated with the crank drive mechanism. Extensive crankcase space provided by the guided pistons permits the engine parts to be arranged in a very compact manner with ample running clearance.
