Abstract

Dispositif de refroidissement d’huile pour un moteur. Dispositif de refroidissement d’huile (6) pour un groupe motopropulseur (2), caractérisé en ce qu’il comprend une entrée d’huile (11), une sortie d’huile (12), un échangeur thermique (13) agencé entre l’entrée d’huile (11) et la sortie d’huile (12), un clapet (14) agencé entre l’entré d’huile (11) et la sortie d’huile (12), le clapet (14) étant agencé en parallèle de l’échangeur thermique (13), le clapet (14) étant destiné à se fermer lorsqu’une pression d’huile (P) devient inférieure ou égale à un seuil de pression (PS), le clapet comprenant un moyen thermosensible (20), le seuil de pression (PS) étant variable en fonction d’une température (T) du moyen thermosensible (20). Figure pour l’abrégé : 5Oil cooling device for an engine. Oil cooling device (6) for a powertrain (2), characterized in that it comprises an oil inlet (11), an oil outlet (12), a heat exchanger (13) arranged between the oil inlet (11) and the oil outlet (12), a valve (14) arranged between the oil inlet (11) and the oil outlet (12), the valve (14) being arranged in parallel with the heat exchanger (13), the valve (14) being intended to close when an oil pressure (P) becomes less than or equal to a pressure threshold (PS), the valve comprising a thermosensitive means (20), the pressure threshold (PS) being variable as a function of a temperature (T) of the thermosensitive means (20).
