Electrically controlled valve for hot fluid

An electrically-controlled valve for circulating hot fluids, the electrically-controlled valve comprising:

• an electromagnetic actuator;
• a valve having an orifice provided with a movable blanking member driven by a rotation shaft at right angles to an axis of the orifice;
• the electromagnetic actuator driving rotation of the shaft, an output axis of the actuator being substantially coaxial with the rotation shaft;
• a front end of the rotation shaft and a front end of the output axis not being in direct contact;
• a coupling between the rotation shaft of the valve and the output axis of the actuator is ensured by a coupling member placed between the front end of the output axis and the front end of the shaft;
• the coupling member having a rotation torque transmission with a misalignment tolerance between the output shaft on the one hand and the rotation shaft of the valve on the other hand;
• a thermally insulating mechanical link between peripheral areas of a body of the actuator and the body of the valve;
• and
• the coupling member comprising a first part fixed to the end of one of the shafts, engaged in a transverse groove formed in a complementary second part fixed to the end of an other of the shafts, the second part having a solid cross section.
