Abstract:
1. An oil separator for removing oil from crankcase gases flowing between a crankcase and an intake manifold of an internal combustion engine, said oil separator comprising: a housing having an inlet and an outlet, the housing including a guide wall having a plurality of holes to allow gases to flow therethrough between the inlet and the outlet; a plate being movably coupled to the housing for movement between a closed position blocking the flow of gases through at least one of the holes in the guide wall and an open position spaced apart from the guide wall to allow gases to flow through all of the holes in the guide wall; a diaphragm having a movable portion coupled to the plate, the diaphragm defining a substantially closed volume continuous with the intake manifold so that pressure changes in the intake manifold causes corresponding displacement of the movable portion and the plate relative to the housing.
