Multi-compartment liquid reservoir (), for a motor vehicle, including a first fluid compartment () equipped with a fluid inlet () and with a fluid outlet (), and a second fluid compartment () equipped with a fluid inlet () and with a fluid outlet (), the reservoir including a liquid-filling neck () and the compartments in fluid communication via at least one passage () allowing one of the compartments to be filled via the other of the compartments, the reservoir further including at least one shut-off system (), able to move between a first position of opening of the at least one passage and a position of closure of the at least one passage, wherein the shut-off system is configured to adopt the first position by default and in the free state, and to be urged into the second position when the reservoir is in operation.

Multi-compartment liquid reservoir for a motor vehicle

A venting tank () for a cooling system of a motor vehicle includes a main wall (), which defines an inner venting volume (V) of the venting tank, the main wall including a bottom () and a cover () opposite one another, an intake () for a heat transfer fluid to be vented within the interior venting volume, and a discharge () for discharging the vented heat transfer fluid outside the inner venting volume. This venting tank () further includes a heat transfer fluid duct (), which crosses through the cover () and the bottom () and includes an inner segment () extending within the inner venting volume (V) from the cover () to the bottom () and whereof an inner volume (V) is separated from the inner venting volume.

Venting tank and automotive vehicle comprising such a tank

The present invention relates to a liquid reservoir for a vehicle that is subjected in service to inclinations in at least two different directions, the reservoir comprising a float well which delimits a bowl containing a float that is able to move depending on the level of liquid in the reservoir. The reservoir is characterized in that the float well comprises at least two retention means positioned successively along a flow path of the liquid as far as the bowl, from the outside toward the inside of the float well, each retention means keeping liquid in the float well if the reservoir is inclined in a set of directions specific to this retention means. The invention also relates to a motor vehicle system comprising such a liquid reservoir and means for binary detection of the level of liquid in the reservoir.
