Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 134 words
A motor vehicle driven by an internal combustion engine with an exhaust supercharger, said engine being connected via engine mountings to a vehicle chassis and including lubricant and coolant circuits, said supercharger comprising: an exhaust gas turbine mounted in a turbine housing; a compressor mounted in a compressor housing and driven by said turbine through a shaft; and a bearing housing between and connected to said turbine and compressor housings supporting said shaft and comprising lubricant and coolant passage means, wherein said bearing housing is connected on one side to the vehicle chassis and on another side to the engine and has an abutment surface abutting against a surface of the engine, said lubricant and coolant passage means opening onto the abutment surface for communication with the lubricant and coolant circuits of the engine.
Claim 2
Dependent Claim 134 words
A motor vehicle driven by an internal combustion engine with an exhaust supercharger, said engine being connected via engine mountings to a vehicle chassis and including lubricant and coolant circuits, said supercharger comprising: an exhaust gas turbine mounted in a turbine housing; a compressor mounted in a compressor housing and driven by said turbine through a shaft; and a bearing housing between and connected to said turbine and compressor housings supporting said shaft and comprising lubricant and coolant passage means, wherein said bearing housing is connected on one side to the vehicle chassis and on another side to the engine and has an abutment surface abutting against a surface of the engine, said lubricant and coolant passage means opening onto the abutment surface for communication with the lubricant and coolant circuits of the engine.
Claim 3
Dependent Claim 31 words
A motor vehicle as claimed in claim 1 further including elastic bearing means connected to the bearing housing for connecting the bearing housing, and hence the supercharger, to the vehicle chassis.
Claim 4
Dependent Claim 20 words
A motor vehicle as claimed in claim 1 wherein the bearing housing constitutes at least part of said engine mounting.
