Abstract (en)
[origin: EP0801990A1] The spray jet has a casing containing a swirl chamber with at least one tangential first channel for input of water, first output co-axial with the swirling axis (12), and second output aperture co=axial with the first one. The second output aperture (21) is at the end of a second channel (14) co-axial with the swirling axis. The second channel has an extension before the second output aperture in direction of flow. This extension is formed in combination with a narrowing of the cross-section (18) of the second channel. The extension may be formed by a conical wall zone of the second channel.
