Abstract
A hydraulically powered fan system for the cooling system of a vehicle. Two hydraulic motors, powered by a hydraulic pump, drive a common fan which cools a radiator. When hydraulic flow in excess of that required to power a single motor is present, a second motor is placed in parallel with the single motor, thereby reducing system pressure, and reducing the power consumed by the pump.
