The valve (1) has an actuator (28) for operating a valve needle (3), where the valve needle has a valve closing body (4) at an injection-sided end. The closing body together with a valve seat surface (6) forms a sealing seat at a seat contact point, where the seat surface is formed at a valve seat body (5). The seat body and the closing body are provided with a rigidity-reducing element. The rigidity-reducing element is designed as a recess i.e. circulating groove, that is partially circulating at an outer circumference of the closing body. The seat surface is made from soft plastic. |
