Abstract
Arrangement for a thermal, steam-powered engine in a submarine vehicle, for example a torpedo. A condenser is so arranged as to separate the exhaust from the engine into a condensable exhaust fraction and into a non-condensable exhaust fraction. A compressor, which is connected to the engine for the purpose of silencing, is so arranged as to compress only the non-condensable exhaust fraction which, after compression, is discharged through an exhaust outlet into the surrounding sea water. The condenser is in the form of a sleeve which for silencing purposes encloses both the engine and the compressor. A sound-deadening gap is arranged between the condenser and the hull of the vehicle.
Claims6
In a power plant for a submarine vehicle, a thermal engine, said engine having at least one operating cylinder and an exhaust gas outlet, an operating piston reciprocatable within said operating cylinder, compressor means for compressing exhaust gases from said engine, said compressor means having at least one compressor cylinder and an exhaust gas outlet, a compressor piston reciprocatable within said compressor cylinder, said compressor piston connected to said operating piston, and means for drainage of compressed exhaust gases from said compressor into the water surrounding said vehicle, said operating piston and said compressor piston being interconnected by means of a flexible piston rod.
