Abstract (en)
[origin: EP1995447A1] Valve assembly (14) of an injection valve (10) and injection valve (10), the valve assembly (14) comprising a first valve body (20) including a central longitudinal axis (A) and comprising a first cavity (24), a second valve body (21) being rigidly coupled to the first valve body (20) and comprising a second cavity (25) with a fluid outlet portion (28), and - a valve needle (22) axially movable in the first cavity (24) and the second cavity (25), the valve needle (22) preventing a fluid flow through the fluid outlet portion (28) of the second cavity (25) in a closing position and releasing the fluid flow through the fluid outlet portion (28) in further positions, the second valve body (21) comprising a passage (40) being arranged between the first cavity (24) and the second cavity (25) directly upstream the second cavity (25) and being designed to enable a fluid flow from the first cavity (24) to the second cavity (25). A filter (42) is arranged directly upstream or inside the passage (40) and is designed to filter fluid flowing from the first cavity (24) to the second cavity (25).
