Water-jet aerator to release the water into the sanitary fixture, comprising a housing made of polymeric material, made harshorne, and a mixer for mixing the water with air, are accommodated in the housing and made of a thermoplastic, while the bottom of the housing reformowana to the ring body cast and performed with outlet holes for water, which is formed by spaced parallel to the direction of flow of walls to restrict the jets, at least in the area of production of water is made of elastic synthetic resin material.

This type of water jet aerators are known from German patent No. 19852411, AS 1/084, 18.05.2000. These aerators end wall in the direction of the stream is covered with a surface layer made of an elastic synthetic resin material. Thanks to this coating greatly creates an obstacle for lime deposits. If lime deposits built up, they can be removed by friction. The manufacture of such water jet aerators are relatively complicated, because in their manufacture the formation of a thin surface layer has high requirements for precision planting tools, because otherwise the transition of the surface layer in the zone boundary to thermoplastic synthetic polymeric material OST the school of the hull will be uneven. In addition, it is desirable to possible lime deposits better removed.

The invention lies in the fact that the rest of the body made of non-thermoplastic and both polymeric materials given form by a two-component casting with the formation of the boundary surfaces between the non-thermoplastic and elastic synthetic polymer material, while the mixer is also made of non-thermoplastic.

According to the further implementation of the bounding streams walls are made of elastic synthetic resin material at the site of their length, at least more than 1.0 mm, in particular 1.5 to 4 mm

In another preferred form of execution of the bounding streams walls are made of elastic synthetic resin material to length, which is about 1.5-3 mm.

This mixer is made as separate from the body of the node.

A device for mixing jets installed in the housing with the lock in the axial and radial directions.

The interface between a non-thermoplastic and elastic synthetic polymer material lie in the same perpendicular to the flow direction of the plane of the cross-sections of the hull.

According to another form of execution of the invention the surface of the section is between La undistorted by Termoplast and flexible synthetic polymeric material in the zone of the shell more surfaces of the cross-section of the wall to limit the stream.

When this wall to restrict the flow area of the interface between a non-thermoplastic and elastic synthetic polymeric material has a stepped shape, at least one step.

Wall to restrict the flow in the zone of the interface surface has a stepped shape on both sides of the interface.

The interface between a non-thermoplastic and elastic synthetic polymer material in the area of the bottom of the housing are essentially perpendicular to the direction of flow.

The invention presents the following drawings, which show

figure 1 - view of the device according to the invention in cross section;

figure 2 is another exemplary embodiment of the device according to the invention in cross section;

figure 3 - case and mixer of the third form of execution of the device according to the invention in cross section.

Shown in figure 1 form of execution is a jet aerator 1 in cross section. Such water jet aerators are also called jet regulators. They have a cylindrical body 2 with a bottom 3, made harshorne, and the mixer 4 for mixing the water with air, are accommodated in the housing 2 and is made of thermoplastic. The mixer communicates with the separation unit 5 jets in the form of two perforated plates. The bottom 3 of the housing 2 reformowana integral to obeche the ke 6 of the housing 2. The housing has an inlet 7 for air. Through these openings the air is sucked created under a separate jets vacuum and mixed with water in the mixer.

The bottom 3 has outlet openings 8 for the outlet of the aeration of the mixture of water and air, and a hole surrounded by a thin bounding the jet walls 9, which essentially coaxially monolithic parts of the mixer. In the present exemplary embodiment, these walls constraints jets have the form of rings 10 are connected to each other in radial ridges 11. The thickness of these bounding walls is, as a rule, a maximum of 1 mm.

Directed to the exit to the water discharge portion 12 of the bottom 3, respectively, of the bounding walls 9, consists of a flexible synthetic resin material. Its hardness And the shore is approx. 60-70. The other part of the housing 2 facing the flow, and the sides 6 are composed of non-thermoplastic with hardness And shore >90. Sections length, bounding the jet walls 9, consisting of an elastic synthetic resin material, 1.5-3 mm, and the boundary surface between the elastic synthetic polymeric material and non-thermoplastic lie in the same perpendicular to the flow direction of the plane of the cross section (55) of the housing 2.

The surface section (56) between the non-thermoplastic and elastic synthetic polymer material in the zone of the shell (6) more surfaces of the cross-section of the wall to limit the jet (9).

Due to the fact that the mixer 4 is made of non-thermoplastic as separate from the body 2 of the node is provided by a simple manufacture of the body by way of a two-component casting.

Shown in figure 2 the form of the water-jet aerator 21 has a housing 22 consisting completely, i.e. including the bottom 23 with the bounding streams walls 29, made of elastic synthetic resin material. Thus, in this design there is no boundary surfaces between the non-thermoplastic and elastic synthetic plastic material. It also provides for the implementation of the mixer 24 in the form of a single node of the non-thermoplastic. At its outer edge a mixer equipped with a flat flange 33, which rests on the upper shoulder 34 of the shell 26 and is located between the shoulder 34 and plate block 25 separate jets. Thanks to the flat flange 23 is generated support for the mixer 24 in the zone of the holder of a water-jet aerator 21, so that the housing 22 has no mechanical or hydraulic loads.

Figure 3 shows the housing 42 in another form of execution in which the body is made integral with the mixer 44. The upper part of the housing and the mixer consists of a non-thermoplastic. In the area of the water outlet portion of the bottom 43 consists of a flexible synthetic on karnego material, which is produced by way of a two-component casting. As the mixer 44 and the bottom 43 is made integral limiting jet wall 49 is designed as lengthening the relevant parts of the walls of the mixer 44, and the transition is made without changing the cross-section. The surface section 55 between the non-thermoplastic and elastic synthetic polymeric material is in the plane of the cross-section of the housing 42. This means that a full cross-section bounding the jet walls 49 suddenly goes from one polymer to another, and surface extending surface section 55 little.

The housing 42 in the monolithic implementation with the mixer 44 is more difficult to manufacture compared to forms 1 and 2, however, it has the advantage that the element 4 according to Fig 1 is no longer manufactured as a separate item and is not mounted. Significantly, the mixer is made of non-thermoplastic and thereby ensures that the incident jet effectively separated and mixed with air, which does not occur when using soft material. On the other hand, this form of execution allows to produce end components bounding the jet walls 49 of soft elastomeric material, so that it becomes possible extension of the ETS is OK to remove lime deposits on the angle before and more than 90° .
