Valve assembly and injection valve

The invention relates to a valve assembly (4) of an injection valve (2), the valve assembly (4) comprising a valve body (10) including a central longitudinal axis (L), the valve body (10) having a cavity (11) forming an inner guide surface (12) in a guide area of the valve body (10), the cavity (11) having a fluid inlet portion (40) and a fluid outlet portion (42), a valve needle (13) axially movable in the cavity (11), the valve needle (13) preventing a fluid flow through the fluid outlet portion (42) in a closing position and releasing the fluid flow through the fluid outlet portion (42) in further positions, wherein the valve needle (13) has an upper end (44) facing the fluid inlet portion (40) and an inner recess (32) extending from the upper end (44) in direction to the fluid outlet portion (42) and enabling a fluid flow inside the valve needle (13), a guide element (34) being arranged in the cavity (11) and being mechanically coupled to the upper end (44) of the valve needle (13) and extending radially to the inner guide surface (12) of the valve body (10) and being designed to guide the upper end (44) of the valve needle (13) inside the valve body (10). The guide element (34) forms a one-piece extension of the valve needle (13) with an inner recess (46) being hydraulically coupled to the fluid inlet portion (40) and the inner recess (32) of the valve needle (13).
