Abstract (en)
[origin: EP2025923A1] The method is carried out with a valve assembly shell (56) comprising a valve body (4) with a cavity (8) having a fluid inlet portion (42) and a fluid outlet portion (44), and a valve seat assembly (32) with a seat plate (26) and a guiding element (28) for guiding the valve needle (10). The valve needle (10) is axially movable in the cavity (24), the valve needle (10) prevents a fluid flow through the fluid outlet portion (44) in a closing position and releases the fluid flow through the fluid outlet portion (44) in further positions, and the valve needle (10) and the valve seat assembly (32) are designed to enable a fluid flow between the fluid inlet portion (42) and the fluid outlet portion (44) following a first flow path (66) through a gap (74) between the valve needle (10) and the guiding element (28) and a second flow path (68) through the valve seat assembly (32).
