Abstract
A reciprocating rotating engine having a combustion chamber and a pumping chamber is provided with two sets of free pistons and pumps vanes each set having two pistons and two pump vanes. The two sets of pistons and pump vanes define four separate combustion chamber portions and pumping chamber portions and reciprocally rotate in concentric circular paths under the force of compression ignited internal combustion forces, pumping and pressurizing hydraulic fluid contained within the pumping chamber.
Claims19
A reciprotating rotating internal combustion engine for producing direct hydraulic work, comprising:
- A) a combustion assembly housing;
- B) a combustion chamber disposed within the combustion housing;
- C) at least two pairs of free pistons disposed within the combustion chamber and dividing the combustion chamber into at least four combustion chamber portions, the free pistons moveable between first piston positions and a second piston positions;
- D) a pumping assembly housing;
- E) a pumping chamber disposed within the pumping housing;
- and
- F) at least two pairs of pump vanes disposed within the pumping chamber and dividing the pumping chamber into at least four pumping chamber portions, the pump vanes coupled to the free pistons so as to be moveable therewith between first pump vane positions and second pump vane positions corresponding to the first and second piston positions respectively;
- G) wherein the free pistons reciprocate between the first and second piston positions under a combustion event force in either one of the first or second combustion chambers to compress combustion gases in the other one of the first or second combustion chambers and to move the pump vanes between the first and second pump vane positions to drive a working fluid through the pumping chamber.

An engine for producing direct hydraulic work, comprising:
- A) a housing having at least one combustion chamber disposed with the housing;
- B) at least two pairs of pistons disposed within the combustion chamber and dividing the combustion chamber into at least four combustion chamber portions, the pistons moveable between first piston positions and second piston positions;
- C) at least one fuel intake port disposed in the housing to allow passage of fuel into the combustion chamber portions;
- D) a pumping chamber disposed within the housing;
- E) at least two pairs of pump vanes disposed within the pumping chamber and dividing the pumping chamber into at least four pumping chamber portions, the pump vanes coupled to the pistons so as to be moveable therewith between first pump vane positions and second pump vane positions corresponding to the first and second piston positions respectively;
- F) the pistons being dimensioned and configured so as to reciprocate between the first and second piston positions under an alternating combustion event force in any one of the combustion chambers to compress combustion gases in another one of the combustion chambers and to move the pump vanes between the first and second pump vane positions to drive a working fluid through the pumping chamber;
- and
- G) at least one exhaust port disposed in the housing to allow for the exit of combustion gases.
