Definitions

  • the invention relates to a jet regulator with a jet regulator housing which, on its outer circumference of the housing, has an external thread for screwing into an internal thread in the water outlet of a sanitary outlet fitting.
  • jet regulators have already been created in order to shape the water flowing out of the water outlet of a sanitary outlet fitting into a homogeneous and non-splashing water jet.
  • the previously known jet regulators are mounted on a sanitary outlet fitting in the area of the water outlet.
  • the external thread of the known jet regulator is provided directly below at least one ventilation opening penetrating the circumferential wall of the jet regulator housing which ventilation opening can also suck the leakage water into the interior of the housing beyond the ambient air, which water could pass through the annular gap through the screw connection between the external and internal threads.
  • the previously known jet regulator is capable of a partial amount of the leakage water passing through the screw connection into the interior of the housing.
  • a solution according to the invention consists in the fact that the aerator housing on its outer circumference of the housing has, at least in some areas, a thread profile that deviates from a continuously helical thread notch around a cylindrical wall as an external thread, which in this area is self-adapting to that in the water outlet provided internal thread cooperates.
  • the jet regulator according to the invention has a jet regulator housing which has an external thread on its outer circumference of the housing. With the external thread provided on the outer circumference of the housing, the jet regulator according to the invention can be screwed into an internal thread in the water outlet of a sanitary outlet fitting in order to shape the water exiting there into a homogeneous, non-splashing and possibly also pearly-soft water jet.
  • the jet regulator housing has a thread profile as an external thread, which at least in some areas deviates from a continuously helical thread groove around a cylindrical wall. In this at least regionally deviating thread profile, the external thread interacts in a self-adapting manner with the internal thread provided in the water outlet in such a way that the screw connection seals particularly well in this area.
  • a further development according to the aforementioned invention provides that a housing end edge area of the jet regulator housing arranged on the outflow side of the external thread is angled in the direction of the inner circumference of the water outlet in such a way that an annular drainage space is formed between this housing end edge area and the inner circumference of the water outlet. Leakage water that gets through the screw connection through the annular zone between the outer circumference of the housing and the inner circumference of the water outlet as far as the outflow-side front peripheral edge area of the jet regulator housing is collected there in an annular drainage space that is formed between the outflow-side housing front edge area and the inner circumference of the water outlet.

At least two adjacent housing parts of the jet regulator housing can subsequently be connected to one another in a non-detachable manner, but preferably in a detachable manner.
  • the water flowing through the jet regulator housing can be shaped particularly effectively if the outflow side, first housing part, on the inflow side, can preferably be detachably connected to a second housing part of the jet regulator housing, which second housing part carries a jet splitter which splits the flowing water into a multitude of individual jets.
  • the jet splitter is designed as a diffuser which has a pot-shaped jet splitter insert, which has a plurality of splitter openings on the circumference of its pot shape, and which has a pot bottom which acts as a water flow to the splitter openings deflecting baffle is formed.
  • the second housing part surrounds the jet splitter insert and if the second housing part is at least in the Area of the cylinder openings tapered conically in such a way that an annular gap is formed between the jet splitter insert and the inner circumference of the housing of the second housing part, which on the outflow side tapers towards an annular opening opening in the housing interior.
  • a preferred development according to the invention provides that a sleeve-shaped guide wall is provided in the jet regulator housing and that at least one ventilation channel is provided between the inner circumference of the jet regulator housing and the guide wall, which leads from at least one ventilation opening arranged on the housing downstream side to the inside of the housing.
  • the jet regulator according to the invention has an outer surface formed by the outer circumference of the housing and an inner surface formed by the guide wall. Since the at least one ventilation channel and the at least one ventilation opening can thus be arranged on the inner surface of the jet regulator designed as a jet aerator, accelerated calcification occurs in the ring zone between the outer circumference of the jet regulator housing and the inner circumference in the water outlet is effectively counteracted.
  • a particularly advantageous, because particularly tight, design according to the invention provides that the downstream edge of the housing front edge of the jet regulator housing is designed as a lip seal that rests on the inner circumference of the water outlet or approximates the inner circumference of the water outlet.
  • the housing end edge, which is designed as a lip seal, on the outflow side can lie tightly against the inner circumference of the water outlet. But it is also possible that this housing front edge the inner circumference of the water outlet is only approximated in such a way that the leakage water collected in the drainage annular space is held there due to the capillary forces, or that an annular gap remaining between the lip seal on the one hand and the inner circumference of the water outlet on the other hand is caused by a possibly desired in this area because it is functionally harmless Calcification is tightly closed.
  • At least one drainage opening is provided in the part of the housing wall of the aerator housing arranged between the downstream edge of the housing and the external thread, from the annular drainage space to the ventilation channel or leads to at least one of the ventilation channels.
  • the functional operation of the jet regulator according to the invention is also secured against unauthorized manipulation if a lattice or net structure of webs crossing one another at intersections is integrally formed on the guide wall on the outflow side.
  • this outflow-side grid or network structure which can also serve as a flow straightener, which combines the water, in particular mixed with ambient air, into a homogeneous water jet, - and the structures behind it inside the housing, cannot be pushed upwards against the direction of flow of the water.

  • a structurally simple and well-sealing embodiment according to the invention in which the external thread forms a thread profile that deviates at least in some areas from a thread notch running continuously around a cylindrical wall in a helical manner, provides that the outer enveloping circle of the internal thread formed into the cylindrical water outlet for screwing certain external thread on the jet regulator housing preferably widens conically towards the outflow side.
  • the external thread with its conically flared thread section digs so deep into the circumferential thread notch of the internal thread provided in the water outlet that this annular zone between the external thread on the outer circumference of the housing and the internal thread in the water outlet is effectively sealed against leakage water from seeping through.

  • at least one formation serving as a liquid bulkhead is provided on the outer circumference of the jet regulator housing, which protrudes into at least one thread notch of the external thread.
  • the formation serving as a liquid bulkhead can dig deep into the thread notch of the internal thread provided at the water outlet, it is useful if the at least one formation extends as far as the enveloping circle surrounding the external thread or at least partially protrudes beyond this enveloping circle.
  • a particularly effective seal is promoted if the at least one formation is designed as a partition wall extending over at least two adjacent thread notches of the external thread.

  • the deviation in the external thread provided according to the invention can additionally or instead also be configured as at least one cam-shaped formation, the cam-shaped formation in the thread notch extending approximately in the longitudinal direction of the notch.
  • the thread profile of the external thread protruding beyond the thread notch widens at least in some areas and preferably in an outflow-side threaded section, so that the external thread can cut deeply into the internal thread in a sealing manner with this outflow-widening thread section.
  • a preferred embodiment according to the invention provides that the aerator is designed without a sealing ring and does not require a sealing ring made of elastic material separately from the aerator housing.
  • the jet splitter is designed as a diffuser.
  • an exemplary embodiment configured differently in comparison provides that the jet splitter is designed as a perforated plate which has splitter openings. So that a corresponding negative pressure arises on the outflow side of the jet splitter designed as a perforated plate, it is advantageous if the splitter openings taper at least in some areas in the flow direction.
