- a circumferential constriction of the flow cross section of the flow channel has the advantage that, depending on the fluid pressure, the cross section of the constriction changes, namely increases with increasing pressure.
- the cross section of the constriction changes, namely increases with increasing pressure.
- the operating points with high pressure are generally not critical for noise generation and need no anyway
