    • PROBLEM TO BE SOLVED: To provide a multi-port rotary valve used to distribute coolant to an engine cooling system.
      SOLUTION: The multi-port rotary valve 10 comprises a valve body 26 having a plurality of outlet ports 30, 32, 34 for directing coolant flow to a radiator circuit 18, a heater circuit 19, and an auxiliary circuit 20. An internal gear driven rotary disc 40 includes a gear driven mechanism 42 located on an inner circumference of the rotary disc. The rotary disc includes two apertures 44, 46 positioned on a top surface of the rotary disc for regulating predetermined flow paths and flow rates to the plurality of ports. An inlet housing body 48 which includes an inlet port 28 mates with the valve body and encases the rotary disc. An actuator 62 which is coupled to a drive gear 64 mounted internal to the inlet housing body is responsive to a control signal for transmitting a torque to the internal drive gear for rotating the disc valve to regulate coolant flow.

    • PROBLEM TO BE SOLVED: To provide an engine cooling device stable in control of warming-up operation and giving no influence to an engine even in circulation of cooling water when receiving a request of a circulation flow rate from a heat exchanging means while operating the engine for warming-up without circulating the cooling water.
      SOLUTION: The engine cooling device 1 includes: a cooling part 2 formed in the engine for flowing of the cooling water; a cooling water temperature sensor part 3 detecting water temperature T of the cooling water; the heat exchanging means 4 using heat possessed by the cooling water; a circulation flow rate varying means 5 varying a circulation flow rate Qc of the cooling water; a circulation water path 6; and a control means 7 regulating the circulation flow rate Qc by controlling the circulation flow rate varying means while referring to the water temperature T upon receipt of a request for a requested flow rate Qr from the heat exchanging means 4. The control means 7 determines a condition of engine warming-up operation according to the water temperature T, performs the warming-up operation without circulating the cooling water by controlling the circulation flow rate varying means, and increases the circulation flow rate Qc to the requested flow rate Qr for a predetermined period of time when receiving the request of the requested flow rate Qr during the warming-up operation.
