摘要

The valve (1) has an actuator (4) arranged in an inner hollow space (3c) of a stationary valve unit i.e. valve needle (3), where the fluid (5) is arranged within the inner hollow space. A flexible sealing unit (6) is arranged at the valve unit. The sealing unit stays in connection with the fluid with its inner side. The sealing unit seals at a valve seat (2b) of a valve body (2) with its outer side or releases a passage opening (2a) of the valve body. The sealing unit exhibits a cap-shape, where the sealing unit is fixed to an end of the valve unit.
