Liquid e.g. oil, separation device for thermal engine crankcase, has bypass separator unit, connected in parallel to separator units, with pressure loss relating to maximum pressure difference between crankcase and admission pipe
Liquid e.g. oil, separation device for thermal engine crankcase, has bypass separator unit, connected in parallel to separator units, with pressure loss relating to maximum pressure difference between crankcase and admission pipe
The device has separator units connected in parallel and in downstream to a pressure adjustment valve, and installed in an air evacuation pipe (8) connecting a crankcase to an admission pipe (4). A bypass separator unit (15) is connected in parallel to the units and is connected by a bypass pipe (14) to one of the pipes. The unit (15) presents pressure loss relating to maximum pressure difference between the crankcase and pipe (4).
