Abstract:
1. An opposed piston engine for providing a supply of pressurized hydraulic fluid comprising: a frame having a first pivot pin and a second pivot pin, the pivot pins defining a pivot pin axis; a first lever pivotally mounted on said first pivot pin and having a first segment and a second segment on one side of the pivot pin, and a third segment and a fourth segment on the other side of the pivot pin; a second lever pivotally mounted on said second pivot pin and having a first segment and a second segment on one side of the pivot pin, and a third segment and a fourth segment on the other side of the pivot pin, whereby said first and second levers are movable in a substantially common plane; a first combustion assembly fixed with respect to said frame and including (i) a combustion cylinder having an inner surface, (ii) a first piston having a face and being slideably and sealably engaged with said combustion cylinder inner surface and in mechanical communication with the first segment of the first lever, and (iii) a second piston having a face and being slideably and sealably engaged with said combustion cylinder inner surface and in mechanical communication with the first segment of the second lever, whereby said first piston and said second piston are substantially opposed and said face of the first piston, said face of the second piston, and said inner surface of the combustion cylinder substantially define a first combustion chamber; a first hydraulic assembly fixed with respect to said frame including (i) a hydraulic cylinder having an inner surface, (ii) a first piston having a face and being slideably and sealably engaged with said hydraulic cylinder inner surface and in mechanical communication with the second segment of the first lever, and (iii) a second piston having a face and being slideably and sealably engaged with said hydraulic cylinder inner surface and in mechanical communication with the second segment of the second lever whereby said first piston and said second piston are substantially opposed and said face of the first piston, said face of the second piston, and said inner surface of the hydraulic cylinder substantially define a first hydraulic chamber; a second hydraulic assembly fixed with respect to said frame including (i) a hydraulic cylinder having an inner surface, (ii) a first piston having a face and being slideably and sealably engaged with said hydraulic cylinder inner surface and in mechanical communication with the third segment of the first lever, and (iii) a second piston having a face and being slideably and sealably engaged with said hydraulic cylinder inner surface and in mechanical communication with the third segment of the second lever whereby said first piston and said second piston are substantially opposed and said face of the first piston, said face of the second piston, and said inner surface of the hydraulic cylinder substantially define a second hydraulic chamber; a second combustion assembly fixed with respect to said frame including (i) a combustion cylinder having an inner surface, (ii) a first piston having a face and being slideably and sealably engaged with said combustion cylinder inner surface and in mechanical communication with the fourth segment of the first lever, and (iii) a second piston having a face and being slideably and sealably engaged with said combustion cylinder inner surface and in mechanical communication with the fourth segment of the second lever, whereby said first piston and said second piston are substantially opposed and said face of the first piston, said face of the second piston, and said inner surface of the combustion cylinder substantially define a second combustion chamber; whereby an expansion of one of the combustion chambers causes a compression in the remote hydraulic chamber, thereby producing pressurized hydraulic fluid.
