Abstract: A device for expansion of liquefied gases, whereby the liquefied gases are used, for instance, as refrigerants for cooling a freezing room. For even distribution of the expanded refrigerant, the liquefied gas is supplied to expansion openings which are arranged inside a cold gas supply pipe. The cold gas supply pipe has an ejector bore hole for aspiration of secondary atmosphere into the cold gas supply pipe. In this way, the expanded refrigerant is finely distributed in the cold gas supply pipe and is mixed with secondary atmosphere.

Abstract: Method and device for dissolving gas, especially carbon dioxide or compressed air, in liquid subject to conditions of pressure and temperature at which, when the solution is subsequently introduced into the combustion air, it will be in a supersaturated state and accordingly finely disperses and distributes itself uniformly. The fuel is forced by a pump (41) into the mixer (11), to which the gas is supplied through a flow regulator (29). Downstream of the mixer (11) are a turbulent section (163), a mixing dome (161), and an exhaust section (164) from which the solution is supplied free of bubbles to the carburetor or injector of an internal-combustion engine, a heating burner, or a reaction-engine burner. The flow regulator (29) is controlled in accordance with the throughput of fuel and regulated by a regulation device (R) in accordance with the percentage of gas in the mixing dome (161) as determined by a pressure gauge (46) or light sensor (51).
