摘要：The inlet side opening (7) to the nozzle opening (4) has a fluid pressurised medium under initial pressure. The outlet side opening (8) has a valve piece (12). The main body (5) of the nozzle is at least partly elastically deformable. Parts of the surfaces (33,33') of the main body of the nozzle next to the inlet side opening are exposed to the inlet-side pressure medium. The main body of the nozzle is elastically deformed by an amount depending on the extent of input pressure. With increasing input pressure, the nozzle body is at least partly elastically deformed in the direction of the valve piece, and or the cross-section of the nozzle opening decreases.
