Abrégé
(EN)

Disclosed is a device for purifying gas from a crankcase of an internal combustion engine, which includes: a transfer wall having a wall portion with a least one narrow accelerated-distribution opening; one gas-flow deflection wall placed behind the transfer wall and defining an impingement and guide surface; an auxiliary opening separate from the narrow opening, made in the transfer wall; and a bypass valve movable to meet a return member and provided to close the auxiliary opening via closure element for moving closer to the surface, the return member extending in the impingement chamber and having a portion that pushes behind the auxiliary opening in the event of overpressure upstream of the transfer wall.
