<p>The invention concerns a valve assembly (11) for an injection valve (10), comprising a valve body (12) including a central longitudinal axis (L), the valve body (12) comprising a cavity (18) with a fluid inlet portion (42) and a fluid outlet portion (40), a valve needle (20) axially movable in the cavity (18), the valve needle (20) preventing a fluid flow through the fluid outlet portion (40) in a closing position and releasing the fluid flow through the fluid outlet portion (40) in further positions, and a guiding device (46) being arranged in the cavity and being designed to guide the valve needle (20) relative to the valve body (12). The guiding device (46) has a first guide element (48) being fixedly coupled to the valve body (12) and a second guide element (50) being fixedly coupled to the valve needle (20). The first guide element (48) comprises a magnetic material with a first magnetic field and the second guide element (50) comprises a magnetic material with a second magnetic field, the second magnetic field being orientated in opposite direction to the first magnetic field.</p> |
