Abstract: A water delivery system for delivering demineralized water to a consuming unit of a motor vehicle, in particular to a combustion engine, encompassing: a water tank having a filling opening; a first aspiration line; a first water pump; a discharge line; a discharge apparatus; a demineralization apparatus for demineralizing water; the first water pump being fluidically connected via the first aspiration line to an internal volume of the water tank; the discharge apparatus being fluidically connected via the discharge line to the first water pump.

Abstract: A water recovery apparatus for a motor vehicle, for recovering water from ambient air, encompasses: a conveying conduit; a condenser device that is embodied to modify the absolute value of at least one dew-relevant state variable of a working gas delivered through the conveying conduit to the condenser device; a water discharge device that is embodied to discharge from the condenser device water condensed out of the working gas by the condenser device, the conveying conduit being embodied to convey ambient air as the working gas to the condenser device, the water recovery apparatus is embodied to deliver working gas continuously to the condenser device.

Abstract: A liquid tank having a tank interior space delimited by a tank wall and fillable with liquid, a withdrawal opening; a retention component that delimits a component interior region in the tank interior space; the component volume of the interior region being less than the tank volume; a partition of the retention component permitting a flow of liquid, out of a component exterior region located outside the interior region but inside the tank volume, through the partition into the interior region and presenting a flow resistance to a flow out of the interior region through the partition into the exterior region, in such a way that the partition exhibits a liquid retention capability with respect to surging movements of liquid in the interior region; the withdrawal opening being arranged in such a way that at least as soon as a level falls below a threshold, the partition is arranged between the withdrawal opening and a liquid quantity received in an exterior region of the tank interior space; the retention compo
