ABSTRACT:
An insert for being mounted in a valve housing (80) or a tubular member for dynamic flow control of a flowing medium. The insert comprises:—a first cup-shaped part (1) provided with an outflow area;—a second cup-shaped part (10) arranged axially displaceably within the first cup-shaped part (1) and provided with an inflow area;—a pressure spring (30) arranged for exerting a force (F) that seeks to force the two cup-shaped parts (1, 10) away from each other. The second cup-shaped part (10) is configured such in relation to the first cup-shaped part (1) that the inflow area of the first cup-shaped part (1) is closed in response to a displacement of the second cup-shaped part (10) in relation to the first cup-shaped part (1). Besides the inflow area of the second cup-shaped part (10) comprises at least one axial inflow slot (12) provided in15a sidewall (18) of the second cup-shaped part (10), which inflow slot (12) is closed in response to the displacement of the second cup-shaped part (10) in relation to the first cup-shaped part (1).
