- the invention relates to a supercharger compressor for a motor vehicle for a supercharging system of a heat engine and a turbocharger supercharger of a motor vehicle engine comprising a compressor according to the invention.
- the electric supercharger that is to say driven by an electric motor, has a much lower response time, and improves the engine torque to low speed and especially during acceleration. This system considerably reduces the engine capacity of the combustion engines, thus reducing fuel consumption.
- the lag time of a gas supercharger is also responsible for the emission of particles when, in a phase of acceleration at low speeds, the injection system tries to provide the requested power by injecting a surplus of fuel.
- the air flow generated by the supercharger will or will not have an effect on the engine torque.
- the air flow generated by the supercharger has no effect on the engine torque. Indeed, it is the fuel injection that acts on the engine torque. However, in the case of a petrol engine, the air flow generated by the supercharger acts on the engine torque. Thus, a failure of the airflow management generated by the supercharger can result in undesired motor torque. The occurrence of an undesired motor torque can pose safety problems for the vehicle.

- the independent control line is intended to be connected to a supervisory element so as to inhibit the activation of the power elements in the absence of airflow control;
- the independent control line is intended to deactivate the power elements in the event of failure of a compressor element, or of an element external to the compressor.
- the invention also relates to a turbocharger supercharging device of a motor vehicle engine.
- the supercharging device comprises at least:
- control means for controlling the supercharging device

- the supercharger 10 further comprises a control line 264 independent of the control member 261.
- the independent control line 264 is arranged to act directly, ie without going through the control member 261 at the level of the power elements 262.
- the independent control line 264 is intended to be connected directly, ie without going through the control member 261, to a supervisory element, for example the engine control system of the vehicle.
