However, the water jets emerging from such water valves only initially have the desired jet band, before the water jet has already contracted after a relatively short free path into a noisy, uncontrolled, non-circular jet. shape

Embodiment Construction

[0023] exist Figures 1 to 7 A jet former 1 is shown in a different view. From Figure 7 It can be clearly seen in the transverse sectional view of , that the jet shaper 1 can be installed in the water outlet 2 of the sanitary water valve. The jet former 1 has a homogenizer 3 which forms the inflow-side end face of the jet former 1 . The homogenizer 3 has a plurality of throughflow openings 4 which are each surrounded and delimited by a fluid-guiding wall 5 . From figure 1 , 3 And it can be clearly seen from 5 to 7 that the fluid-guiding wall 5 is formed as a grid-like structure.

[0024] exist figure 1 As can be seen in , the jet former 1 has a jet width l greater than the jet depth t in order to generate a smooth water jet strip. From Figure 4 and 7 It can be seen in the transverse sectional view of the homogenizer 3 that a fluid guide 6 is connected downstream of the homogenizer 3, which tapers nozzle-like at least in some regions in the flow direction. On both s...

Abstract

The former (1) has a homogenizing device with a set of passage holes that are limited by a flow guiding wall, where the former has a larger stream width compared to stream depth (t) for producing a flat water flow volume. A flow guide (6) is provided upstream or downstream and narrows in a partial area in a flow direction. The flow guide has edge areas (7, 8) with a larger flow cross section relative to a longitudinal middle area (9), where the edge areas extend in both sides of the guide in a longitudinally extending manner.

Description

technical field [0001] The invention relates to a jet former, which is arranged in the water outlet of a sanitary water valve and has at least one homogenizer with a plurality of through-holes which are each surrounded and delimited by a fluid-guiding wall. Background technique [0002] In the water outlet of conventional sanitary water valves, a jet former designed as a jet regulator is usually installed, which is intended to form the incoming water flow into a homogeneous, non-splashing water jet. For this purpose, known jet regulators have a homogenizer which has a honeycomb or grid-like or net-like structure with a plurality of flow holes which are each surrounded by flow-guiding walls limited. In this case, further functional units may optionally be connected upstream of the homogenizer on the inflow side. [0003] Known jet regulators generally have a circular flow cross-section adapted to the water valve. But people have been working hard to design such water valve...
