ABSTRACT:
In an automotive vehicle wherein the cooling fan for the internal combustion engine is driven hydraulically by a flow of a first propellant hydraulic fluid, while the power steering device for the steering system is driven hydraulically by a flow of a second propellant hydraulic fluid, reservoirs for storing the first and second propellant hydraulic fluids are provided as first and second tank portions, respectively, of a common reservoir tank, so that the first propellant hydraulic fluid which is more apt to be heated up by friction loss is cooled down by the second propellant hydraulic fluid which remains at ambient temperature as effectively cooled through the power steering fluid circulation system.
