Electrically controlled actuating device incorporating a thermostatic function, and valve

An actuating device, comprising:

• a fixed portion forming a frame comprising an inlet intended to receive a fluid, a main outlet and a second outlet and a return device for exerting a mechanical force on a movable portion;
• a movable portion comprising:
• a shutter comprising a rod moving in translation between an open position of the second outlet and a closed position of said second outlet under the effect of the mechanical force;
• a thermostatic device comprising a conical turning disc integral with a collar movable around the rod of the shutter, the turning of the disc above a known critical temperature driving the shutter to the closed position of same;
• a control device allowing a holding force for holding the shutter to be generated, the control device being able to be controlled in such a way that below the critical temperature, the opening or the closing of the shutter results from the balance of forces between the holding force and the mechanical force.
