The present invention relates to a kinetic turbopump assembly for a closed loop, in particular of Rankine cycle type, associated with an internal-combustion engine () with a drive shaft (), notably for a motor vehicle, wherein one () of the faces of said engine carries accessories () of this engine, and at least one winding roller () for a rotary motion transmission belt () connecting at least said accessories to drive shaft (). According to the invention, the assembly comprises a rotary motion transmission path (T) between shaft () of the turbopump and said winding roller.

Turbopump assembly for a closed circuit, particularly of the Rankine cycle type, associated with an internal-combustion engine, in particular for a motor vehicle

The present invention relates to a closed circuit operating on a Rankine cycle, the circuit comprising at least one compression and circulation pump for a working fluid in liquid form, a heat exchanger over which a hot source is swept in order to evaporate the fluid, means for expanding the fluid in the form of a vapor, a cooling exchanger swept by a cold source to condense the working fluid, a reservoir of working fluid, and working fluid circulation pipes for circulating the fluid between the pump, the heat exchanger, the expansion means, the condenser and the reservoir. The circuit comprises a device for draining the fluid contained in the heat exchanger.

Closed circuit functioning according to a Rankine cycle with a device for the emergency stopping of the circuit, and method using such a circuit

A method and device for detecting and extracting a gaseous fluid contained in a closed loop operating on a Rankine cycle are provided. The loop includes a multiplicity of constituents with, successively, a circulation and compression pump for a working fluid, a heat exchanger associated with a hot source, an expansion machine, a cooling exchanger, a working fluid tank and circulation pipes connecting these constituents. The method and device measure the temperature (Tr&#xe9;elle) and the pressure (Pr&#xe9;elle) of the working fluid at a point of the loop when this loop is at rest, and, as soon as the measured pressure (Pr&#xe9;elle) exceeds a threshold value (Pliquide satur&#xe9;) for a given ambient temperature (T), activate equipment for extracting the gaseous fluid in order to discharge it from the loop.
