Abstract
A valve for controlling a fluid, e.g., fuel, has a closing element and a valve seat. The valve seat has a sealing region and a valve seat region adjoining the sealing region. The closing element seals on the sealing region, the sealing region and the valve seat region merging with one another directly and without a step. A hardness of the sealing region is less than a hardness of the closing element.
Claims6
A valve for controlling a fluid, comprising:
- a closing element;
- a valve seat having a sealing region and a valve seat region adjoining the sealing region;
- and
- a guide region for guiding the closing element;
- wherein the guide region has a hardness less than the hardness of the closing element;
- wherein the guide region has a hardness greater than the hardness of the sealing region;
- wherein the closing element seals on the sealing region at an inner surface of the sealing region;
- wherein the sealing region and the valve seat region merging with one another directly and without a step at an outer surface of the sealing region;
- wherein a hardness of the sealing region is less than a hardness of the closing element;
- wherein the sealing region is configured as an annular elastomeric sealing element situated in a groove in the valve seat;
- and
- wherein the annular elastomeric sealing element has a rectangular cross-section, the cross-section being formed by a plane orthogonal to the inner surface and outer surface of the sealing region.
