Abstract: A tool to screw/unscrew a screwing element, having a module comprising a lever extending radially from and rotatable around a drive axis, a first transmission element rotatable around the drive axis by the lever, a transmission module comprising a second transmission element cooperating with the first element, a third transmission element rotatable around a screwing/unscrewing axis parallel to, and spaced from, the drive axis, a transmission system comprising an element transmitting the second element rotation to the third element, and an adapter with a fourth transmission element cooperating with the third element, and a cavity confirming to the screwing element. The tool includes a wedge with at least one rotatable adapter mounted thereon. The wedge comprises two support surfaces on planes parallel to the drive axis and disposed opposite one another to define a groove receiving an end of the transmission module on the third element side.

Abstract: A method for filling a reservoir on board a motor vehicle by a reserve cartridge. The reservoir includes a filler pipe, including a device for sealed attachment of the cartridge to the pipe. The cartridge includes a latching device configured to allow the fluid to flow from the reserve cartridge into the reservoir filler pipe only when the cartridge is attached in a sealed manner to the device on the pipe. The reserve cartridge is attached in a sealed manner to the pipe attachment device and the reserve cartridge latching device is unlatched so that the fluid can flow from the reserve cartridge into the filler pipe.

Abstract: An additive tank for a vehicle having an internal combustion engine, the tank including a flexible bag which contains the additive and is connected to a device allowing the flexible bag to be pressurized in order to meter the additive.
