Abstract

Abstract Translated from French Moyens de ventilation comportant un capteur de température placé au contact d'un fluide caloporteur circulant dans le moteur ainsi qu'un organe de commande sensible à ce capteur pour assurer l'alimentation du ou des moteurs d'entraînement des moyens de ventilation en fonction des variations de la température du fluide caloporteur. Ledit capteur de température comprend un composant (10) sensible à une plage continue de températures. Ce composant est raccordé en tant qu'élément d'entrée, à une boucle (4 à 6,8) de réglage continu de l'énergie appliquée au (x) moteur (s) (9) des moyens de ventilation, boucle qui comprend un circuit à seuil (19, 20, 21) fixant la valeur inférieure de ladite plage de température. Ventilation means comprising a temperature sensor placed in contact with a heat transfer fluid circulating in the engine as well as a control member sensitive to this sensor to supply the drive motor or motors of the ventilation means as a function of the variations in the temperature of the heat transfer fluid. The temperature sensor includes a component (10) responsive to a continuous range of temperatures. This component is connected as an input element to a loop (4 to 6.8) for continuously adjusting the energy applied to the motor (s) (9) of the ventilation means, a loop which comprises a threshold circuit (19, 20, 21) setting the lower value of said temperature range.
