Abstract
This invention is a piston in cylinder engine using water injection into a relative vacuum heated to steam by expanding in the cylinder and by an electric arc or other heat source. The resulting steam explosion applies a work force on the piston. The piston has jet nozzles uncovered at the end of its work stroke to jet the piston to help propel it during the return stroke and to form a vacuum in place of the usual compression stroke. The piston has a cover plate with tapered pins depending into jet nozzles through the piston to block the jet nozzles during the main work stroke.
Claims21
A reciprocating piston engine having a power and an exhaust stroke, a least one cylinder and a piston therein having at least one opening through it head end to back end to exhaust the fluid in the head end during the exhaust stroke, and a lid for sealing said opening closed during the power stroke, and means for opening said lid during the exhaust stroke and for closing the lid during the power stroke;
- a water supply and metering means connected to said water supply and said engine to mete out a charge of water for each power stroke of said engine, said metering means including an injector set to be controlled by a vacuum in the head end of said cylinder to suck in said charge of water to explode the water into steam, and means for supplying heat to said cylinder to maintain said steam long enough to run the power stroke of said engine.
A reciprocating piston for an engine, said piston having at least one jet nozzle hole through it from head end to back, and a lid for alternately covering and opening each said jet nozzle hole together for exhausting through the piston to jet propel the piston during the exhaust stroke, and at least one separate hole through said piston having a shaft therethrough slip-fit for supporting and guiding said lid.
The method of operating a reciprocating piston steam engine by forming a vacuum by movement of the piston away from the head end of the cylinder at the start of the work stroke, sucking with the vacuum a metered amount of water into the vacuum in the cylinder at the start of the work stroke when the vacuum is strong enough to cause the water to explode into steam, supplying sufficient heat to keep the steam from condensing for the work stroke, and exhausting the cylinder by opening at least one jet hole through the piston during the return stroke to form an exhaust jet to help power the return stroke.
An engine as in claim 15 with at least one exhaust jet hole through the piston having a head end and an exhaust end having a work stroke and an exhaust stroke a lid for closing the jet hole during the work stroke,
- at least one rod-like member running through the piston extending from the head end to beyond the exhaust end, said lid being secured to said rod to open and close said jet hole,
- stop means at the head end of said cylinder to engage said rod to close said cover at the top end of the exhaust stroke, and stop means connected to said engine to be hit by said rod to push the rod back to open the cover for the exhaust stroke, and means to hold said cover in position relative to said piston between ends of travel of said piston.
A reciprocating piston engine having only a power and exhaust stroke having at least one cylinder with piston therein and connecting rod and crank shaft to produce rotary motion, the improvement being:
- said cylinder having at the head end a water metering vacuum injector connected for injecting a metered amount of water into the head end of the cylinder when holding a vacuum down to a preset value at the start of the work stroke connected and set to open to let a charge of water be sucked in with the vacuum when low enough to explode said water to steam above a minimum temperature to drive the engine.
