Title
(EN) DEVICE FOR CONTROLLING THE SUPPLY OF A COMBUSTIBLE GAS TO A BURNER OF A HEATING APPARATUS
(FR) DISPOSITIF DE RÉGULATION D'ALIMENTATION EN GAZ COMBUSTIBLE DE BRÛLEUR D'APPAREIL DE CHAUFFAGE
Abstract
(EN)
A device for controlling the supply of a combustible gas to a burner of a heating apparatus comprises: - a valve (6) with a respective valve seat (6a) which is associated with a corresponding closure member (6b) which is provided with a respective control rod (7) for opening the valve seat, - a system for amplifying the movement of the control rod (7) which has a snap-fit spring (26) which acts on the rod (7) and a pushing element (27) which in turn acts on the snap-fit spring (26) in order to activate a snap-fit movement of the spring, there acting on the pushing element (27) a first end (28a) of a lever (28), which is hinged at a fulcrum location which is positioned at an opposing second end (28b) of the lever, - actuator means for the movement of the lever (28) which are operationally associated with the lever in a position between the opposing lever ends (28a, 28b) for the control of the lever about the fulcrum location for the resultant movement of the closure member (6b) away from and towards the valve seat (6a), the actuator means comprising a linear actuator element (30) with a converse piezoelectric effect, in which the linear movement of the actuator is proportionally correlated with the signal of an electric control voltage which is applied to the actuator.
(FR)
L'invention concerne un dispositif de régulation de l'alimentation en gaz combustible d'un brûleur d'un appareil de chauffage, le dispositif comprenant : - une soupape (6) doté d'un siège (6a) de soupape respectif associé à un élément de fermeture correspondant (6b) muni d'une tige de commande respective (7) permettant d'ouvrir le siège de soupape ; - un système d'amplification du déplacement de la tige de commande (7) comportant un ressort encliquetable (26) destiné à agir sur la tige (7) et un élément de poussée (27) destiné à agir, à son tour, sur le ressort encliquetable (26) afin d'activer un mouvement d'encliquetage du ressort, actionnant ainsi, sur l'élément de poussée (27), une première extrémité (28a) d'un levier (28) articulé au niveau d'un emplacement de pivot positionné au niveau d'une seconde extrémité opposée (28b) du levier ; - des moyens d'actionnement du déplacement du levier (28) associés fonctionnellement au levier dans une position entre les extrémités (28a, 28b) opposées du levier afin de commander le levier autour de l'emplacement de pivot permettant le déplacement résultant de l'élément de fermeture (6b) à l'opposé du siège de soupape (6a) et vers ce dernier, les moyens d'actionnement comprenant un élément actionneur linéaire (30) doté d'un effet piézoélectrique inverse, dans lequel le déplacement linéaire de l'actionneur est corrélé proportionnellement avec le signal d'une tension de commande électrique appliquée à l'actionneur.
