Abstract
The present invention relates to a process for regulating the temperature of a fluid circuit comprising a thermostatic valve, which consists in maintaining a leak rate through the valve once the valve has been opened a first time in order to eliminate the temperature fluctuations of the fluid around a regulation temperature. Two thermodilatable elements with different expansion temperature thresholds are used. The invention further relates to a thermostatic valve intended to regulate the temperature of a fluid around at least one value and comprising at least a first thermodilatable element. The valve further includes a second thermodilatable element for maintaining a controlled leak rate as soon as the valve has been opened (a first time).
