Abstract
Abstract An exhaust gas turbocharger for a diesel engine, the turbocharger including a compressor, an exhaust gas turbine, and a shaft joining the compressor and turbine. A flywheel is mounted on another shaft, and a device, such as a freewheel, alternatively couples and uncouples the flywheel shaft and turbocharger shaft. The flywheel shaft is in two sections, and a summation mechanism, such as a planetary gear arrangement, is between the two shaft sections. The summation mechanism is controlled by a hydrostatic device and/or an electronic device. A brake is provided for selectively preventing rotation of the flywheel shaft section between the summation mechanism and the turbocharger shaft.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
An exhaust gas turbocharger for a diesel engine, comprising: (a) a turbocharger including a compressor, an exhaust gas turbine, and a shaft joining the compressor and turbine, (b) a flywheel having a two-section flywheel shaft, (c) a freewheel for alternatively coupling and uncoupling the flywheel shaft and turbocharger shaft, (d) a summation mechanism between the two sections of the flywheel shaft, (e) a hydrostatic device for controlling the output of the summation mechanism, the hydrostatic device including a pump adapted to be driven by the diesel engine, a hydromotor for driving the summation mechanism, and a high pressure accummulator between the pump and hydromotor.
Claim 2
Dependent Claim
104 words
An exhaust gas turbocharger for a diesel engine, comprising: (a) a turbocharger including a compressor, an exhaust gas turbine, and a shaft joining the compressor and turbine, (b) a flywheel having a two-section flywheel shaft, (c) a freewheel for alternatively coupling and uncoupling the flywheel shaft and turbocharger shaft, (d) a summation mechanism between the two sections of the flywheel shaft, (e) a hydrostatic device for controlling the output of the summation mechanism, the hydrostatic device including a pump adapted to be driven by the diesel engine, a hydromotor for driving the summation mechanism, and a high pressure accummulator between the pump and hydromotor.
Claim 3
Dependent Claim
18 words
An exhaust gas turbocharger as defined in claim 1 wherein said summation mechanism includes a planetary gear arrangement.
Claim 4
Dependent Claim
19 words
