INTERNAL COMBUSTION ENGINE WITH FLUID PISTON Russian patent published in 2010 - IPC B63H11/02 F02F3/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production, in particular ICE working chamber with fluid piston. ICE working chamber with fluid piston represents an enclosed vessel. Said vessel is fitted on engine rotor and furnished with duct with valve to feed working fluid in working chamber and with hydraulic gate to rule out ingress of gas mix therein. Working chamber vessel is furnished also with duct incorporating valve to feed fresh combustion mix or its components into working chamber and valve to discharge a portion of working fluid from working chamber, hydraulic gate to prevent losses of fresh combustion mix and nozzle to create working fluid jet. Note that working chamber vessel has channel incorporating the valve designed to force combustion product residues out of working chamber and nozzle to create jet of said residues, as well as duct designed to keep compressed combustion mix in working chamber and, with combustion mix ignited, to force working body to nozzle that creates working body jet.

EFFECT: varying compression ration in wide range to expand operating performances.
