Beschreibung
Zusammenfassung:	An electric machine for an electric or hybrid motor vehicle includes a cooling system suitable for spraying a dielectric heat transfer fluid onto active parts of the machine and a reservoir for collecting, by gravity, the fluid flowing through an orifice in a wall separating the active parts and the reservoir. The machine also includes, at the orifice, a flap attached to the wall and suitable for closing the orifice, a resilient device to open the flap under the effect of gravity on the liquid, and a non-return device to hold the flap closed when a force exerted on the fluid in the reservoir brings the liquid against the flap.
