Title (EN) COOLING SYSTEM FOR AN AUTOMOTIVE VEHICLE
(FR) SYSTÈME DE REFROIDISSEMENT POUR UN VÉHICULE AUTOMOBILE
Abstract: front page image
(EN)The invention relates to a cooling system for an automotive vehicle, comprising at least one closed cooling system including at least one electrically powered compressor, the circuit being provided with a bypass branch capable of establishing a direct hydraulic communication between the high-pressure part of the circuit, corresponding to the discharge of the compressor, and the low-pressure part of the circuit, corresponding to the suctioning of the compressor, in which a corresponding bypass valve is installed; with a check valve in the high-pressure part of the circuit, arranged after the bypass branch; and with a suction pressure regulating valve, arranged in a low-pressure part of the circuit, upstream of the bypass branch.
(FR)L'invention porte sur un système de refroidissement pour un véhicule automobile, comprenant au moins un système de refroidissement fermé comprenant au moins un compresseur électrique, le circuit comportant une branche de dérivation qui peut établir une communication hydraulique directe entre la partie haute pression du circuit, correspondant à la décharge du compresseur, et la partie basse pression du circuit, correspondant à l'aspiration du compresseur, dans laquelle une soupape de dérivation correspondante est installée. Selon l'invention, le circuit comporte également un clapet anti-retour dans la partie haute pression du circuit, disposé après la branche de dérivation; et une soupape de régulation de pression d'aspiration, disposée dans une partie basse pression du circuit, en amont de la branche de dérivation.
