20080298989ROTARY AND TRANSLATING DISPLACEMENT DEVICE - A rotating-to-translating conversion device having a piston member oscillating within a casing where a rotating shaft is positioned through the piston. The interaction between a groove member between the piston and the shaft is such that an engagement member positioned within the groove will provide an oscillating motion of the piston with respect to the shaft, and a sealing system provides a seal between first and second regions within the casing.12-04-2008
20100037851INTERNAL COMBUSTION WATER INJECTION ENGINE - An internal combustion system and a water injection nozzle to position a water mist within an internal chamber of an internal combustion engine. In one form, the apical cone of the injection is altered with respect to the position of the piston within the interior chamber. In another form, the air fuel mixture is charged at an opposing charge to the water mist to create a water droplet gaseous fuel mixture for combustion within the anterior chamber.02-18-2010
