Abstract

L'invention concerne un dispositif électromécanique, notamment électrovanne (1), comportant : - Une bobine (20), - un élément (40) mobile sous l'effet du champ magnétique généré par la bobine, - une résistance électrique (2) de type CTN reliée électriquement en série avec la bobine et couplée thermiquement à celle-ci de façon à compenser au moins partiellement la variation de la résistivité de la bobine avec la température.The invention relates to an electromechanical device, in particular a solenoid valve (1), comprising: - a coil (20), - an element (40) movable under the effect of the magnetic field generated by the coil, - an electrical resistance (2) of CTN type electrically connected in series with the coil and thermally coupled to the latter so as to compensate at least partially for the variation of the resistivity of the coil with the temperature.
