Abstract

Circuit de refroidissement pour les têtes ou culasse de cylindres d'un moteur à combustion interne du type des moteurs refroidis par circulation forcée de liquide de refroidissement dans un circuit qui comprend une pompe branchée directement sur les têtes des cylindres. Ce circuit est caractérisé en ce qu'il comprend deux conduites 21, 22 qui communiquent avec le côté basse pression de la pompe 15, chacune de ces conduites étant reliée à un groupe correspondant de têtes de cylindres, de manière que la pompe à circulation forcée prélève du fluide de refroidissement dans les têtes 14 de cylindres par l'intermédiaire de ces conduites. Le dispositif est particulièrement destiné aux moteurs Diesel.Cooling circuit for the heads or cylinder heads of an internal combustion engine of the type of engines cooled by forced circulation of coolant in a circuit which includes a pump connected directly to the heads of the cylinders. This circuit is characterized in that it comprises two conduits 21, 22 which communicate with the low pressure side of the pump 15, each of these conduits being connected to a corresponding group of cylinder heads, so that the forced circulation pump draws cooling fluid from the cylinder heads 14 via these pipes. The device is particularly intended for diesel engines.
