Suggested is an injection valve for a gas or liquid medium, having a blocking body and a valve seat. The blocking body can be moved between an opening position where the blocking body is spaced from the valve seat and a closing position where a blocking body-contact area of the blocking body comes in contact with a valve seat-contact area of the valve seat by using a sealing method. Moreover, the blocking body-contact area and/or the valve seat-contact area have a microstructure increasing friction between the blocking body-contact area and the valve seat-contact area. |
