Abstract
The present disclosure relates to a valve, preferably an exhaust gas or gas exchange valve, having a valve head which has a front face and a rear face, the front face of the valve head including an edge region and a bulge towards the outside which has a crest region. The valve, in order to reduce the mass of the bulge of the valve head, including a laterally outer part section of the edge region that is of flatter configuration in comparison with a laterally inner part section of the edge region, or the edge region includes at least one discontinuity in cross section.
Claims19
A valve comprising:
- a valve head which has a front face and a rear face, the front face of the valve head including an edge region and a bulge which has a crest region, wherein in order to reduce the mass of the bulge of the valve head, a laterally outer part section of the edge region is of flatter configuration in comparison with a laterally inner part section of the edge region, or the edge region includes at least one discontinuity in cross section, wherein the valve is configured as a solid-body valve and wherein a neutral axis of the valve head extends in sections on a load side of an imaginary reference plane, the reference plane running through an effective centre of a valve seat face of the valve head and transversely with respect to a valve stem of the valve.
A valve/valve seat combination comprising:
- a valve including a valve head which has a front face and a rear face, the front face of the valve head including an edge region and a bulge which has a crest region, wherein in order to reduce the mass of the bulge of the valve head, a laterally outer part section of the edge region is of flatter configuration in comparison with a laterally inner part section of the edge region, or the edge region includes at least one discontinuity in cross section, wherein the valve is configured as a solid-body valve and wherein a neutral axis of the valve head extends in sections on a load side of an imaginary reference plane, the reference plane running through an effective centre of a valve seat face of the valve head and transversely with respect to a valve stem of the valve;
- and
- a valve seat for the valve.
A motor vehicle, comprising:
- a valve/valve seat combination, the combination further comprising,
- a valve including a valve head which has a front face and a rear face, the front face of the valve head including an edge region and a bulge which has a crest region, wherein in order to reduce the mass of the bulge of the valve head, a laterally outer part section of the edge region is of flatter configuration in comparison with a laterally inner part section of the edge region, or the edge region includes at least one discontinuity in cross section, wherein the valve is configured as a solid-body valve and wherein a neutral axis of the valve head extends in sections on a load side of an imaginary reference plane, the reference plane running through an effective centre of a valve seat face of the valve head and transversely with respect to a valve stem of the valve;
- and
- a valve seat for the valve.
