ELECTRICALLY CONTROLLED ACTUATING DEVICE INCORPORATING A THERMOSTATIC FUNCTION, AND VALVE

摘要

A actuating device includes a fixed portion forming a frame including an inlet intended to receive a fluid, a main outlet and a sampling outlet and a return device for exerting a mechanical force on a movable portion; a movable portion including a shutter moving between an open position and a closed position; a thermostatic device including a conical turning disc, 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 valve results from the balance between the holding force and the mechanical force.

1. 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.
