Abstract

An exhaust gas turbo-supercharger for a vehicle engine, which is connected via engine mounting to the chassis of the vehicle and is provided with an exhaust gas turbo-supercharger. The supercharger has a bearing housing 1 which is provided with lubricant and coolant passages 5 and 6 or 8 and 9, and which is designed to form an engine mounting. The housing is connected to the vehicle chassis 21 by an elastic bearing 20, and is flange-mounted to a surface 11 of the cylinder crank case 12. The lubricant and coolant passages 5 and 6 or 8 and 9 open in the abutment surface 10 of the bearing housing 1 against the cylinder crank case 12 and are in communication with the lubricant and coolant circuit 14 and 15 or 16 and 17 of the engine.
