Abstract
A mechanism is disclosed for actuating the intake and exhaust valves of a reciprocating multiple cylinder external combustion vapor expansion engine in either forward and reverse rotation. Electrical solenoid and pressure actuating valve mechanisms responding to a sophisticated digital computer program replaces the cam shafts, push rods, adjustable tappets, throttle, fuel injection, and cooling systems of a conventional internal combustion Diesel engine. The computer integrates the many system variables, including, temperature, pressure, speed, friction, mass, and acceleration to obtain the optimum efficiency of shaft work output.
Claims7
A reciprocating vapor expansion power generating device comprising:
- a base housing having a crankshaft mounted therein by bearings, a piston attached to a crankshaft by a connecting rod, the piston sliding within a tubular cylinder secured to the base housing by tie rods passing through an exhaust chamber to clamp a cylinderhead assembly to the base housing, the cylinderhead assembly containing a plug-disc type intake valve attached to a bias disc, a piston type dump valve for controlling the opening and closing of said intake valve, a flat-disc type exhaust valve with a bias spring holding said exhaust valve normally closed, an external source of high pressure vapor continuously supplied to the intake valve port, external actuating means mounted above said cylinderhead assembly to control both said dump valve and said exhaust valve when responding to computer commands, the external actuating means, opens the intake valve for said vapor to press against the piston inducing shaft rotation, close the intake valve, the vapor expanding against the piston until being released through said exhaust valve to the atmosphere.
