Valve assembly for an injection valve and injection valve

摘要

An injection valve comprises a valve assembly. The valve assembly (4) includes a central longitudinal axis. The valve body (4) comprises a cavity (8) and a fluid outlet portion (24) abutting the cavity (8). A valve needle (10) is axially moveable in the cavity (8) and prevents a fluid flow through the fluid outlet portion (24) in a closing position and releases the fluid flow through the fluid outlet portion (24) in further positions. A guide element (44) is designed to guide the valve needle (10) in the cavity and is further designed to filter fluid flowing in the cavity towards the fluid outlet portion (24).
