Definitions

  • the invention relates to a jet regulator with a jet regulator housing which has an external thread on its outer circumference of the housing for screwing into an internal thread in the water outlet of a sanitary outlet fitting, the aerator housing on its outer circumference of the housing having at least one cross-sectional expansion of the same material and integrally formed thereon with the housing section of the aerator housing carrying the external thread has, which can be placed sealingly on the front side and / or the inner circumference side of the water outlet.

  • This ventilation channel 18 leads from the at least one ventilation opening 9 arranged on the housing downstream side to the housing interior. Since the water, which is divided into individual jets in the jet splitter, experiences an increase in speed in the annular gap 15, a negative pressure arises according to Bernoulli's equation on the outflow side of the annular gap 15 in the area of the ring opening 16, the ambient air from outside through the ventilation duct 18 into the mixing zone 20 Part of the interior of the housing sucks.

  • the outer circumferential circle of the external thread on the flow regulator housing intended for screwing with the internal thread 3 formed in the cylindrical water outlet 4 can widen conically towards the outflow side in the jet regulator shown . Due to the conicity of the external thread 2, the uppermost thread on the inflow side still sits with play in the internal thread, while the next but one thread already protrudes deeper into the thread notch of the internal thread due to the conicity of the external thread beginning there.
