System for managing the flow of cooling liquid in cooling circuit in motor vehicle comprises control and distribution modules with temperature sensor and control flap to selectively allow the cooling fluid to enter one circuit or another

摘要

The device (20) has a body (21) mounted on a engine cylinder and provided with a rotating movable unit (30) delimiting, at the right, a distribution module (40) and on the left, a control module (50). The control module has a high pressure chamber HP and a low pressure chamber BP connected to a discharge electro valve. The distribution module has a high pressure HP distribution chamber (41) receiving the cooling liquid and in which is a rotating annular stop (31) having distribution orifices (35,36), with various outlets distributed in the periphery of this chamber and corresponding to the branches of this circuit also with a temperature sensor. The annular stop has a control flap (37) movable between these chambers as a function of the difference of pressure between the two chambers. There is a also a computer controlling the electro valve as a function of motor control strategy. An Independent claim is also included for the method using this device.
