An electro-magnetic actuator unit including anarmature axially movable in the cavity and designed to actuate the valve needle via theretainer element, and a pole piece fixedly coupled to the valve body and including aninner recess, the retainer element being at least partially arranged in the inner recess.The pole piece includes a stop element extending radially into the inner recess of thepole piece. The stop element has a stop surface facing the fluid outlet portion and theretainer element. The stop surface of the stop element limits the axial movement of theretainer element.
