  • the means for heating the fluid comprise a chamber inside which a resistance is arranged, the fluid being in direct contact with the thread of said resistance. Due to the low nominal voltage of the installation, the water presents a lot of resistance to the passage of the current, thus producing no short circuit.
  • said resistance is a helical resistance, being welded at one of its ends by a low temperature welding, so that when the fluid is at a higher temperature, of a predetermined value, said welding is broken by deactivating the resistance.

Abstract

Système permettant de répandre un fluide sur la surface externe du pare-brise d'un véhicule. Ce système est caractérisé en ce qu'il comprend au moins une enceinte (2) intégrée dans le réservoir (1) de fluide permettant de nettoyer le pare-brise du véhicule. Dans ladite enceinte sont disposés des moyens (5) destinés à chauffer un volume prédéterminé de fluide à une pression constante, des moyens (3, 7) destinés à éjecter le fluide provenant du réservoir vers le pare-brise et des moyens de régulation (6) des moyens de chauffage et d'éjection précités. Le circuit que parcourt le fluide sert à nettoyer le pare-brise et aussi à acheminer le fluide chaud. Ce système permet d'enlever le gel de la surface externe du pare-brise rapidement et aisément ou d'en enlever la buée. En outre, on peut utiliser le circuit pour nettoyer le pare-brise, pour défaire le gel ou enlever la buée à l'extérieur en actionnant ou non les moyens de chauffage du fluide.
