Abstract
A unique reciprocating piston device that uses one or more special cams and yokes to replace the functions normally provided by crankpins and connecting rods. The cams have noncircular finite jerk lift surfaces which provide continuous positive positioning of the yokes and pistons. Various cams can be configured to overcome the performance limitations imposed by crank and rod controlled pistons for a wide variety of engines and pumps. Preferred embodiments of this invention create a flexible, reliable, efficient and smooth running device for compressing, expanding and transferring fluids. In one specific application, an internal combustion engine is designed such that its pistons spend a greater portion of time near the top and bottom of each stroke than is possible with a crankshaft type engine.
