Abstract

PURPOSE:To commonly use a fluid pump, a flow rate control valve, and piping, by a method wherein a fluid motor to drive a cooling fan and a water pump is connected in series to the fluid pump through a delivery flow rate control valve. CONSTITUTION:A hydraulic motor 3 for a water pump is pivotally mounted to a hydraulic motor 4 for a water pump disposed in a cooling water circulating passage 30 running around a water jacket 32 and a radiator 42. The hydraulic motor 4 for a cooling fan is pivotally mounted to a radiator 42 and a cooling fan 41 to effect blast to a capacitor 43 for an air conditioner. The hydraulic motor 3 for a water pump and the hydraulic motor 4 for a cooling fan are connected in series to a hydraulic pump 1 through a flow rate control valve 2. The flow rate control valve 2 is controlled by a controller 5 to which a water temperature sensor and an air conditioner switch are inputted, and work ing fluid to the two motors 3 and 4 is controlled.
