Estimating the term…
The circuit includes an internal volume for receiving a cooling fluid, a stopper for selectively closing an opening giving access to the internal volume, and ensuring element that the cooling fluid can be discharged via a discharge outlet. The respective discharge and access openings to the internal volume are distinct from each other, and a flap valve, which is detachably fixed in relation to the stopper and which is moveable between respective closure and release positions of the access opening when the flap valve is disconnected from the stopper, is also provided. The flap valve exclusively moves from its closed position when the pressure prevailing inside the internal volume is lower than a predefined pressure value.
A cooling circuit for a motor vehicle with an internal combustion engine, comprising a body having at least one pipe adapted to extend in the vicinity of the engine and of the radiator of said vehicle, said body defining an internal volume for receiving a cooling fluid, said circuit also comprising a stopper for selectively closing an opening giving access to this internal volume, said stopper being removably fixed on the body, as well as an element for ensuring discharge of said cooling fluid via a discharge outlet, wherein the access opening for access to the internal volume and the discharge outlet are distinct and a flap valve is removably fixed on the stopper, said flap valve being movable, when disconnected from the stopper, between respective closure and release positions of the access opening, said flap valve being adapted to leave the closure position only when the pressure in the internal volume becomes lower than a predetermined pressure.
