Abstract (en)
[origin: WO9427729A1] A nozzle sleeve (1) contains supply channels (2), feeding channels (3, 5, 22, 24), concentric channels (4, 6), tangential channels (8) and a ring-shaped channel (7), as well as a core (13) which covers the various channels, so hermetically that they form ducts into which a liquid flows in and is pushed in a predetermined direction of rotation into the large concentric channel (4), then flows in the opposite direction of rotation into the small concentric channel (6) and finally flows once again in the predetermined direction of rotation through the feeding channels (5) and reaches a ring-shaped channel (7) from where it is sprayed out through the bore (9) of the nozzle sleeve (1). The changes in the direction or rotation cause turbulences which represent a braking force for the liquid flowing under pressure. The intensity of this braking force is directly proportional to the liquid pressure, so that the rate of flow per unit of time is held at least approximately constant.
