Abstract
A hydraulic cooling system for vehicles utilizing a hydraulic pump driven by the vehicle engine, the pump, preferably, having high and low volume chambers, a shroud adapted to be associated with the vehicle engine cooling radiator, a fan driven by hydraulic fluid pressurized by the pump for producing air flow through the shroud and the engine cooling radiator, and the hydraulic circuit between the pump and the fan motor includes a reservoir and a control valve sensitive to the engine coolant temperature. The control valve is located within the reservoir, and the reservoir is mounted upon the shroud and includes heat exchanging fins exposed to the air passage within the shroud. The entire combination of components may be pre-assembled and shipped and installed as a unit.
