Abstract
Abstract An electric power generating device recovering the energy of the exhaust gases of an internal combustion engine, comprising a speed-reducer mounted between the engine and a transmission shaft and a turbo-alternator set driven by the energy taken from said exhaust gases and the turbine of which is operatively connected to said reducer through a reversible transmission system with variable speed keyed in follow-up relationship to the speed variations of said transmission shaft.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
An electric power generating device operated by recovering the energy from the exhaust gases of an internal combustion engine, comprising speed-reducing means mounted between said engine and a transmission shaft and a turbo-alternator set driven by said energy taken from said exhaust gases, the turbine of said turbo-alternator set being operatively coupled to said speed-reducing means, wherein the improvement consists in that said turbine is operatively coupled to said speed-reducing means through the agency of a variable-speed reversible transmission member keyed in follow-up relationship to the actual speed variations of said transmission shaft.
Claim 2
Dependent Claim
93 words
An electric power generating device operated by recovering the energy from the exhaust gases of an internal combustion engine, comprising speed-reducing means mounted between said engine and a transmission shaft and a turbo-alternator set driven by said energy taken from said exhaust gases, the turbine of said turbo-alternator set being operatively coupled to said speed-reducing means, wherein the improvement consists in that said turbine is operatively coupled to said speed-reducing means through the agency of a variable-speed reversible transmission member keyed in follow-up relationship to the actual speed variations of said transmission shaft.
Claim 3
Dependent Claim
15 words
A device according to claim 1, wherein said transmission member is a hydrostatic transmission system.
Claim 4
Dependent Claim
31 words
A device according to claim 2, further comprising an intermediate pressure fluid intake-like tapping provided between both stages of said transmission system and connected to a control arrangement driving auxiliary equipment.
Claim 5
Dependent Claim
41 words
A device according to claim 1, further comprising an auxiliary working fluid generator for feeding said turbine and change-over means for connecting the input of said turbine either to the exhaust of said engine or to the output of said generator.
Claim 6
Dependent Claim
29 words
A device according to claim 4, further comprising boiler means through which the input of said turbine is connectable through said change-over means to the exhaust of said engine.
