Abstract: A separation assembly comprises a housing and a plate. The housing comprises an inlet and an outlet. The plate is positioned within the housing between the inlet and the outlet. The plate comprises a wall, at least one aperture, and at least one chimney comprising an inner surface surrounding the at least one aperture and an outer surface. The chimney extends from an upstream side of the wall and encompasses only a portion of a flow path between the inlet and the upstream side of the wall such that fluid can flow radially beyond the outer surface of the at least one chimney in the housing between the inlet and the wall.

Abstract: An air-liquid separation assembly for separating air and liquid from an air-liquid mixture comprises a housing through which fluid flows, a main separator positioned within the housing, and a sub-separator. The sub-separator is positioned within the housing before or after the main separator and defines a plurality of slots. Each of the plurality of slots is positioned either between adjacent baffles of the sub-separator or between a baffle of the sub-separator and a portion of the housing. The plurality of slots are positioned next to each other in a direction substantially perpendicular to the direction of fluid flow through the housing. The plurality of slots comprises a first subset of slots and a second subset of slots. The second subset of slots extends at a different angle than the first subset of slots such that fluid flows through the first subset of slots and the second subset of slots at different angles.

Abstract: A crankcase ventilation system comprises a housing defining an internal volume structured to receive a. rotating air/oil separator element. The housing has a housing inlet structured to receive a fluid and a housing outlet defined tangentially in a sidewall of the housing which is structured to allow the fluid to exit the housing. An outlet conduit is fluidly coupled to housing outlet. The outlet conduit comprises an outlet conduit first portion axially aligned with the housing outlet, and an outlet conduit second portion positioned downstream of the outlet, conduit first, portion. A swirl breaking structure is positioned in at least one of an outlet conduit inlet and the outlet conduit second portion. The swirl breaking structure is configured to disrupt swirling flow of the fluid into the outlet conduit so as to reduce a pressure drop experienced by the fluid as the fluid flows from the housing into the outlet conduit.
