Abstract
A valve assembly includes a valve body, a valve needle and a first guiding element that axially guides the valve needle. The first guiding element is bottle shaped and is axially deformable at least in part. The first guiding element is fixedly coupled to the valve needle in a bottle neck section of the first guiding element, and coupled to the wall of the valve body in an axial end section of the first guiding element remote from the bottle neck section. Based on these features of the first guiding element, an axial displacement of the valve needle away from the closing position results in a widening of an outer shape of the first guiding element at least in a fixation section to press it against the wall of the valve body.
