Abstract
Thermostat comportant un circuit magnétique comprenant un aimant permanent et un capteur thermomagnétique. Le matériau constitutif de l'aimant 14 présente un produit d'énergie maximal d'au moins à peu près 50 kJ/m, de préférence de plus de 100 kJ/m**3 ; entre l'aimant 14 et le capteur 10, dans la position extrême en laquelle l'aimant est le plus proche du capteur, il existe un entrefer minimal entre l'aimant et le capteur; la force élastique est réglable dans cette position extrême sans variation de cet entrefer minimal, et l'autre position extrême de l'aimant 14 est réglable. Application : thermostat.Thermostat comprising a magnetic circuit comprising a permanent magnet and a thermomagnetic sensor. The material constituting the magnet 14 exhibits a maximum energy product of at least approximately 50 kJ / m, preferably of more than 100 kJ / m ** 3; between the magnet 14 and the sensor 10, in the extreme position in which the magnet is closest to the sensor, there is a minimum air gap between the magnet and the sensor; the elastic force is adjustable in this extreme position without variation of this minimum air gap, and the other extreme position of the magnet 14 is adjustable. Application: thermostat.
