<p>The valve (1) has an adjustment element (3) comprising a sealing element (5) on a side facing a nozzle (4). The sealing element rests on a nozzle seat (40) in a closed position of the valve, and is lifted from the seat in an opened position of the valve. A drive (2) positions the adjustment element relatively to the nozzle for opening and closing the nozzle. The sealing element is supported at the adjustment element via a spring element (8) and movable relative to the adjustment element. The adjustment element is provided with a tappet (6) that is connected with the sealing element. The spring element is made of a two-dimensional elastic material i.e. spring steel. The spring element is designed as a meander spring, disk spring, star spring and leaf spring. The drive is designed as an electromagnet.</p> |
