ECCENTRIC CHAMFER AT ENTRY OF BRANCHES OF FLOW CHANNEL Russian patent published in 2012 - IPC F01D5/18 F23R3/00 

FIELD: machine building.

SUBSTANCE: flow channel comprises a main channel, a branching channel in which the direction of flow is perpendicular to the flow direction of the main channel, and the inlet of the branching channel, which is located in the wall of the main channel and is set by the edge that contains the upper edge of the stream and the lower edge of the stream. A chamfer is designed at the top edge of the inlet relative to the flow. The lower edge of the inlet relative to the flow is a sharp edge, formed by the right angle between the wall of the branching channel and the wall of the main channel. The chamfer at the top edge relative to the flow has a form that is eccentric relative to the longitudinal axis of the branching channel.

EFFECT: reduced pressure loss.
