  • Valve and method for producing a valve
    Patent number: 11060494
    Abstract: A valve is provided, in particular an injection valve, having a valve seat and a valve needle which extends along a closing direction for the most part, the valve seat having a valve-seat surface, and a valve-closing element is mounted on an end of the valve needle facing the valve seat, the valve-closing element being able to be moved between an open position and a closed position, and the valve-closing element together with the valve-seat surface forming a sealing seat in the closed position, the valve-closing element having a greater core hardness and/or surface hardness than the valve-seat surface.

  • Valve for controlling a fluid with increased sealing action
    Patent number: 10125735
    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.
