Definitions
- the invention relates to an installation part for a sanitary outlet fitting, in particular a jet regulator or a backflow preventer, wherein the mounting part has a mounting part housing, in which is provided a sliding part which for changing the Flow cross-section in the built-in part housing against the restoring force a reset element from a starting position functional position is guided.
- a sliding part is provided, which for example as a jet splitter insert or as a closing body serves.
- the sliding part used in the known built-in parts is for changing the flow cross section in the built-in part housing against the restoring force of a restoring element Starting position slidably guided into a functional position.
- the solution to this problem according to the invention consists in the built-in part of the type mentioned in particular in that the sliding part and the return element as a one-piece plastic injection molded part are trained.
- the sliding part and Reset element designed as a one-piece injection molded part.
- the invention installed injection molded part inexpensively in large quantities manufacture and assemble with comparatively little effort, is the manufacture of the installation part according to the invention at least insofar as possible inexpensively with little effort.
- the return element is designed as a return spring.
- the return spring can be used as a plastic spiral be formed, which are integrally formed on the injection molded part is.
- the sliding part and the return spring or the same reset element made of different plastic material exist and form a multi-component injection molded part and that preferably an elastomer as the material for the restoring element is provided.
- the sliding part can be made of a hard and be manufactured according to stable plastic material, while the one-piece molded from an elastomer return spring high restoring force.
- a particularly advantageous development according to the invention provides before that the integrally molded return element as Coil spring or bellows spring is formed.
- a bellows spring is characterized by a uniform and comparatively high restoring force.
- the flow cross section can seal as best as possible, it is advantageous if at least one sealing ring or similar sealing element on the sliding part is integrally formed and if the sealing element is preferred made from the elastomer provided for the return element is.
- Embodiment according to the invention looks particularly advantageous and easy to manufacture Embodiment according to the invention that the injection point for the injection component forming the reset element centrally on Sliding part provided on the side facing away from the return spring and that the spray component at the injection point over at least a feed channel with the restoring element and / or optionally are connected to the sealing element.
- FIGS. 1 and 2 show two different built-in parts 1, 10 shown, of which the mounting part 10 in the usual manner in the Mouthpiece of a sanitary outlet fitting, not shown here can be used and the built-in part 1 in the course of the water pipe arranged connector housing is housed. While that in figure 1 built-in part 1 formed as a backflow preventer 2, the built-in part 10 serves as a jet regulator.
- Each of the built-in parts 1, 10 has a built-in part housing 2, in which one as a closing or valve body (Fig. 1) or as a jet splitter insert (Fig. 2) serving sliding part 3 is provided.
- the Sliding part 3 of the built-in parts 1, 10 is for changing the Flow cross section in the built-in housing 2 between one in Figures 1 and 2 shown starting position and a functional position slidably guided.
- Each sliding part is by means of a reset element 4 held in its initial position, wherein this return element 4 is designed here as a bellows spring.
- the sliding part 3 and the return element 4 are the Installation parts 1, 10 as a one-piece plastic injection molded part educated. While the sliding part 3 from a hard and is made according to stable plastic material is as Material for the restoring element is an elastomer, for example Silicone or santoprene.
- This essentially consists of the sliding part 3 and the restoring element 4 formed two-component injection molding can be inexpensive Manufacture in large quantities and with a comparatively small number Assemble effort. As a result, the manufacture of the built-in parts 1, 10 possible with little effort.
- This guide stem 5 is in the guide opening a central guide sleeve 6 slidably guided on the downstream end of the built-in parts 1, 10 is provided.
- the restoring element 4 engages approximately centered on one end of the sliding part 3 and is coaxial to the arranged with the sliding part 3 guide handle 5.
- the one serving as the valve body Sliding part 3 of the built-in part 1 protrudes outwards Sealing ring 7 is provided, which is in the direction of flow Pf1 conically expanding valve seat 8 on the built-in housing 2 of the Installation part 1 interacts.
- the restoring element 4 designed as a bellows spring Installation parts 1, 10 is designed as a compression spring.
- This compression spring holds the sliding part 3 of the built-in part serving as the valve body 1 in the initial or closed position shown in Figure 1. In this closed position, it lies on the outer circumference of the sliding part 3 provided sealing ring 7 on the valve seat 8 of the installation part 1 on.
- Pf1 Liquid flow becomes the sliding part 3 from its closed position moved into a functional or open position, not shown here.
- moves against the control flow direction Pf1 flowing liquid surge the sliding part 3 back into its Starting or closing position, whereby the built-in part 1 a counteracts unwanted reflux.
- the sliding part 3 of the installation part 10 shown in FIG. 2 has on its upstream front edge an outwardly projecting Ring flange 13 on. On this ring flange 13 are transverse to Passage openings 14 oriented in the plane of the pane are provided. This Passage openings are on the outflow side as open-edge slots or grooves formed. It is roughly hat-shaped or pot-shaped Sliding part 3 in the area of a stop ring 15 of the built-in part 10 arranged. This stop ring 15 has a right angle to Ring jacket arranged stop side 16 to which there is a guide slope 17 connects to the flow deflection. This guide slope 17 forms one widening against the flow direction Pf2 Cone section.
- the baffle surface 19 of the sliding part 3 is with the passage openings 14 directly in the outflow direction Distance arranged opposite.
- the flow guidance along the guide bevel 17, through the passage openings 14 and at the Baffle surface 19 of the sliding part 3 results in a particularly good beam splitting.
- the sliding part 3 can Close the valve in its upper, shown in Figure 2 Move starting position.
- the sliding part 3 When raising the sliding part 3 in its starting position lifts the sliding part 3 from the stop side 16 from, so that the passage openings 14 to the outflow side are open to the edge.
- Something different in this position Flow direction with an essentially axial component Dirt particles that are in front of the passage openings 14 if necessary, safely removed. A jam or fixing these particles is largely excluded.
