Abstract
A valve cone comprises a cylindrical body extending along a longitudinal axis. The body has a cylindrical surface with at least one, axially extending recess. The recess extends inside a contour line between a first end position at a first end of the cylindrical body and a second end position, which is located between the first end of the body and the opposite second end of the body. The cross-sectional area of the recess, in a plane perpendicular to its longitudinal axis, gradually decreases from a maximum value close to the said first end towards the second end position. A valve cone of the type described above is arranged in a valve. In a method for manufacturing the valve cone, the radial recesses are formed by cutting in a single axial-radial cutting motion.
