FIELD: mechanical engineering; motors and pumps.SUBSTANCE: invention relates to fuel supply circuits to combustion and devices for production of combustion products of high pressure or high speed. Combined pump-displacement fluid component feed circuit hydro-reacting fuel (HRF) to consumer, containing consumer with cooling system, oxidizer pump, oxidizer pump drive turbine, which is rotated by flow of reaction products and fuel and oxidiser, fuel tank tightly divided into cavity with HRF and cavity for displacement body by means of bellows, bag or moving or elastic baffle, connection lines, fuel components feed and discharge line, valves, control and control members, wherein oxidant is used as displacing body to feed liquid hydro-reacting fuel to consumer, wherein oxidizer for displacement of liquid hydro-reacting fuel is taken from consuming equipment cooling system tank, hence it is of high temperature. Extra heat exchange surface between the displacing oxidizer and HRF is composed by the chambers for HRF displacing oxidizer with their limiting surfaces in, at least, partial contact with the HRF in the tank. Oxidiser pump drive turbine can be actuated by superheated water steam, taken from consuming equipment cooling system. Circuit can contain heat exchanger.EFFECT: decreased weight and its volume, lower costs of feed and HRF feed, simplified provision variety of operation conditions of system operation, better controllability and stability of underwater or two environment vehicles, which use invention, and simpler and cheaper design feed system.4 cl, 2 dwg |
