Abstract
A flow control assembly is provided, including a member and a wall. The member has a surface, a flow diverting member and a rail member. The rail member is situated upstream of the flow diverting member. The flow diverting member and the rail member each project from the surface of the member. The flow diverting member has a distal end. The wall is disposed in relation to the member to create a clearance gap between the distal end of the flow diverting member and the wall. A fluid path is created between the member and the wall, and flows from an upstream section and through the clearance gap. A first chamber and a second chamber are defined by the wall and located upstream of the clearance gap.
