Abstract
A control valve for a cooling circuit of an automobile engine comprises a valve body (12) provided with an input (20) and a number of outputs (22, 24, 26) for a coolant, an adjustment member (14) designed to rotate about a rotation axis (XX), an electric motor (30) coupled to the adjustment member (14) to bring it into chosen angular positions to control the distribution of the coolant between the outputs (22, 24, 26), and an absolute position sensor (50) coupled in rotation to the adjustment member (14) to deliver an output signal (S) representative of the angular position of the adjustment member (14), wherein the motor is able to be driven by a position controller (CP) which is designed to receive the output signal (S) and which is used to adjust the angular position of the adjustment member (14).
