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 1):
An arrangement for controlling a flow of laden gases issuing from a crankcase of an internal combustion engine, intended to be placed between an upstream inlet area supplying the laden gases and a downstream area in communication with an air intake recirculation system, comprising:\n a check valve having a closing member movable by positive pressure so as to define a first passage for a first flow direction; a bypass valve set in motion by negative pressure and enabling the defining of a second passage for a second flow direction that is opposite the first flow direction; a pipe segment having a stationary seating surface adapted to define, with the bypass valve, the second passage; an elastic biasing member engaged with one among the check valve and the bypass valve; wherein the bypass valve defines a seat on which the closing member of the check valve comes to rest in a closed configuration of the first passage, the elastic biasing member exerting a restoring force directed in a first direction referred to as the forward direction, which urges the bypass valve towards a position which closes the second passage, the closing member of the check valve and the bypass valve being adapted to retreat in a second direction called the rearward direction that is opposite to the first direction, under the effect of negative pressure.
