| 摘要 |
The invention relates mainly to a valve (16) for a motor vehicle combustion engine cooling circuit, having: - at least one inlet orifice (28) intended to be connected to a coolant outlet of said combustion engine, - at least three outlet orifices (29a-29c) intended to be in communication with a first heat exchanger, such as a radiator, a second heat exchanger, such as a unit heater, and a bypass circuit, respectively, and - open/close elements (30a-30c) that are actuated by control means (31a-31c) to selectively open or close an associated outlet orifice (29a-29c), characterized in that said control means (31a-31c) are configured to allow at least two different open positions of the open/close elements (30a-30c) associated with said first heat exchanger and said bypass circuit, so as to obtain at least two different coolant flow rates in said combustion engine, notably when coolant is flowing through the radiator branch. |
