Abstract:
The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.

Claim (Index 15):
A method for controlling a flow of laden gases issuing from a crankcase of an internal combustion engine, implemented by using the arrangement as defined in  claim 1 , the bypass valve of the arrangement being set in motion by negative pressure, the method comprising:\n routing a flow of laden gases between an inlet and an air intake recirculation system of the engine, passing through the pipe segment of the arrangement, allowing the flow of laden gases to travel in a first flow direction through the pipe segment, during normal operation with positive pressure, via the first passage defined between the check valve of the arrangement which is in a forward position and the bypass valve held in contact position against the stationary seating surface formed by the segment, and closing the first passage by moving the check valve rearward until it comes into contact with the bypass valve, when the pressure becomes negative, and allowing the bypass valve to move away from the stationary seating surface when a negative pressure threshold is reached in order to clear the second passage between the bypass valve and the stationary seating surface and thereby obtain a second flow direction through the segment, opposite to the first flow direction.
