摘要： A mechanical system comprising a sump and at least one component to be lubricated or cooled arranged in the sump, the mechanical system comprising a lubricating fluid system provided with a lubricating fluid and a tank arranged in the sump. The tank is a leaking tank and is situated above said at least one component to be lubricated or cooled, the lubricating fluid flowing out of the tank by force of gravity, so as to reach said at least one component to be lubricated or cooled. The lubricating fluid system has at least one lift flow generator connected by at least one filling line to the tank and to at least one suction point present in a bottom of the sump. The lift flow generator fills the tank with the lubricating fluid present in said bottom at least during a starting phase.

摘要： A vehicle provided with a power plant having at least one heat engine, the vehicle having an air-conditioning system comprising a fluid circulating in a fluid circulation system, the fluid circulation system comprising at least one pump configured to cause the fluid to circulate in a fluid circuit. The vehicle comprises one injection member per heat engine configured to inject the fluid into the associated heat engine, the vehicle comprising a back-up circuit fluidly connecting the fluid circulation system to each injection member, the back-up circuit comprising a distribution device controlled by a controller to authorize, on command, circulation of the fluid towards an injection member.

摘要： A power transmission system having at least one inlet speed-reducing gear and a main speed-reducing gear, each inlet speed-reducing gear comprising an inlet pinion meshing with an inlet gearwheel. The inlet gearwheel is constrained to rotate with a main pinion of the main speed-reducing gear, the main pinion meshing with a main gearwheel. At least one inlet gearwheel is secured to reversible connection means in order to be capable of driving a first additional drivetrain connected to an additional rotor.
