Abstract (en)
[origin: WO2018167638A1] The invention relates to an optimized foam former (1) for foaming a foam-water concentrate, which foam former consists of a curved grate having diamond-shaped openings (13) and sharp edges (12). The structure of the foam former increases the foam formation and ensures uniform distribution of the foam over a large area. Existing water sprinklers having a nozzle (3) and a spray disk (2) can be provided with the foam former (1) and thus converted into foam sprinklers in a simple manner. The foam former (1) is arranged in such a way that the foam former (1) protrudes beyond the spray disk (2) toward the nozzle (3).
