A valve seat ring for an intake passage of an engine controlled by a valve, comprising a conical valve seat annular surface and a portion of the intake passage connected to the rear of the ring. and a wall portion narrowing the cross-section of the intake passage, in which the flow opening 2 is provided with an annular ridge 8 in the − plane. by a portion of the outer surface 7 of and on the other side a cylindrical wall surface 9
, the outer surface 7 expands from the narrowest point in a hopper-like or trumpet-like manner and coaxially toward the valve seat annular surface 3, and the wall surface 9
is formed by cutting off a part of the annular protrusion 8 by eccentric and axially parallel milling of the valve seat ring 1, and the uncut portion of the annular protrusion 8 is formed by the assembly of the valve seat ring 1. A valve seat ring for an intake passage of an engine controlled by a valve, characterized in that it forms a part that narrows the cross section of the intake passage in the closed position. 2 The radius of milling and therefore the radius R9 of the cylindrical wall surface 9 is
The radius R7 of the narrowest point of the annular protrusion is equal to or slightly larger than the radius R7, and the center point M9 of cutting is set at the center point M1 of the valve seat ring 1 so as not to cut the conical valve seat annular surface 3.
The valve seat according to claim 1, which is eccentric by a distance X from . 3 The uncut portion of the annular protrusion 8 is the annular protrusion 8
extends from the narrowest point toward the inlet side plane of the flow opening, forming a straight or round wall surface when viewed in cross section, and the contact ends at surface 10, and at the inlet side plane of the valve seat ring 1. the maximum inner diameter is equal to the inner diameter at that point of the intake passage 2;
The valve seat ring according to claim 1 or 2, wherein the intake passage 2 has a circular cross section at least in a plane where it connects to the valve seat ring 1.
