摘要：
A cooling fan for an internal combustion engine hydraulically driven by a flow of propellant hydraulic fluid is controlled of its rotational speed by a system which includes a device for sensing a value representing the operating temperature of the engine, a device for sensing the operating temperature of the propellant hydraulic fluid, and a device for controlling the flow of the propellant hydraulic fluid, so as to increase the flow rate of the propellant hydraulic fluid when the operating temperature of the engine increases and also when the operating temperature of the propellant hydraulic fluid increases.
