  • Non-return valves of the crankcase ventilation system are integrated into the V-space cover, whereby the V-space cover forms the sealing seat of the check valves.
  • One or more check valves may usefully be arranged in the module when using the turbocharged and / or supercharged engines. These check valves are part of the crankcase ventilation and serve to initiate the cleaned or de-oiled by the oil separator vent gases from the crankcase depending on the operating point of the internal combustion engine in different sections of the intake and prevent unwanted

Abstract

La présente invention concerne un module d'aération (1) destiné à un moteur à combustion interne comprenant un moteur à cylindres en V et un couvercle de chambre en V (2) qui recouvre la chambre formée entre les deux rangées de cylindres du moteur à cylindres en V, et un dispositif de condensation de vapeur d'huile raccordé à un système d'aération de carter de vilebrequin du moteur à combustion interne, le couvercle de chambre en V (2) étant fait de matière plastique, présentant des canaux moulés (3), et formant une paroi de boîtier du dispositif de condensation de vapeur d'huile. Selon l'invention, les canaux (3) ont une forme tubulaire et alimentent le moteur à combustion interne en agent de refroidissement et/ou en lubrifiant.
