FIELD: transport machine building.
SUBSTANCE: invention relates to a valve device for gaseous medium having a valve body with a hole through which medium flows in direction of flow. Hole is limited by circumferential surface in the valve body. Partition wall is located in the gap inside the valve body with the possibility of displacement perpendicular to the flow direction to influence the flow by means of the hole. Gap separates circumferential surface into part of circumferential surface on inlet side and part of circumferential surface on outlet side. Part of circumferential surface on the outlet side has the first edge facing the partition and the second edge opposite to the partition. Valve device comprises one geometrical element designed to ensure non-uniformity of the first edge.
EFFECT: technical result is the creation of a valve device, during which noise is reduced.
