Abstract

An electrically controlled valve for the circulation of hot fluids is made up of an electromagnetic actuator and a valve. The valve has an opening provided with a movable sealing member driven by a rotation shaft perpendicular to the axis of the opening, the electromagnetic actuator driving the rotation of the shaft, the output shaft of the actuator being substantially coaxial with the rotation shaft. The front end of the rotation shaft and the front end of the output shaft are not in direct contact. The coupling between the rotation shaft of the valve and the output shaft of the actuator is provided by a coupling member placed between the front end of the output shaft and the front end of the shaft. The coupling member transmitting rotation torque with a misalignment tolerance between the output shaft and the rotation shaft of the valve. The valve also having thermally insulation for mechanical connection between peripheral areas of the body of the actuator and the body of the valve.
