Description

The invention relates to a sanitary insert, with a base body, which provides a radially oriented outer surface, and an elastic control body, wherein the main body forms a regulator core with a control profile and between the control body and the control profile, a control gap is formed, so that an opening cross-section of the control gap is variable by a pressure-dependent application of the control body.

The invention further relates to a use of a sanitary insert.

Such inserts are known and are used, for example as a flow regulator, to realize a desired flow rate per unit time in a working range pressure-independent.

The invention has for its object to provide a flow regulator with the smallest possible external dimensions.

According to the invention, this object is achieved by the feature of claim 1. In particular, according to the invention is thus proposed to solve the above problem in a flow regulator of the type described above, that the main body forms a radially outwardly open receptacle that the control body is arranged in the receptacle and that an outer diameter of the control body is tuned to an outer diameter of the outer surface , Thus, no wall is required on the outside of the control body, and the space required for this purpose can be saved. The flow rate regulator according to the invention can thus be manufactured with a radial outer dimension, which is essentially determined by the control body. This additionally avoids adverse effects on a control behavior, which would result from an otherwise required miniaturization of the control body.

The configuration of the receptacle according to the invention thus makes it possible that the control body is preferably accessible from all sides in a non-installed situation of the insert radially from the outside.

The terms "radial", "axial", "circumference" can - unless otherwise stated - on a longitudinal axis of the flow rate regulator, which can coincide with a general flow direction to understand.

In one embodiment of the invention can be provided that the outer diameter of the control body is smaller than the outer diameter of the outer surface. In this case, it is favorable if the control body has an outer diameter that is substantially the same as the outer diameter of the outer surface, but does not project beyond the outer surface. Preferably, the outer diameter of the control body is at most 20% smaller, more preferably at most 10% smaller than the outer diameter of the outer surface. Thus, an available space for the largest possible rule body is available.

In one embodiment of the invention can be provided that the receptacle is formed in an occupied by the control body axial portion radially outwardly open. Thus, an arrangement is provided in which no components are provided between the control body and a volume flow surrounding the regulator or receiving inner wall of a tubular portion. The flow regulator can thus be arranged as close as possible to this inner wall. Thus, a space utilization of an available inner cross section can be improved by the control body.

In one embodiment of the invention can be provided that the outer surface is formed on a wall of the base body, wherein the outer diameter of the control body is greater than an inner diameter of the wall. Thus, it can be achieved that a radially outermost point of the control body protrudes beyond an inner boundary of the wall. For a dimensioning of the control body thus a wall thickness of the wall is available, so that the largest possible radius of curvature of the control body is accessible in the circumferential direction. This results in a particularly advantageous control behavior.

In one embodiment of the invention can be provided that the outer diameter of the outer surface defines a maximum radial outer dimension of the body. The advantage here is that no space is given away inside the female tubular section. Rather, the entire available inner cross section of the section can be used in order to use the largest possible control body, that is, a control body with, for example, the largest possible outside diameter.

The outer surface may in this case be cylindrical or otherwise, for example, as a freeform formed. The outer diameter can be defined here by the regions lying radially on the outside.

In one embodiment of the invention can be provided that adjacent to the outer surface a radially inwardly deformable sealing element is formed. Thus, one is Seal and / or an axial holding in a tubular section structurally and manufacturing technology easily accessible. Preferably, the sealing element is deformable at least up to the outer diameter of the outer surface. Unnecessary free spaces between the outer surface and the tubular portion are thus avoidable. The elastic deformability has the further advantage that manufacturing tolerances or diameter variations of the tubular section can be compensated. It is particularly favorable when the sealing element is formed as a molded, preferably circumferential, sealing lip. Thus, the sealing element is easily integrally formed with the housing and can preferably take over all-sided sealing functions and / or holding functions.

In one embodiment of the invention can be provided that cross-section of the body has a round basic shape. Thus, the flow regulator can be used for example in standardized water outlets and / or pipe system without additional adaptation measures.

In one embodiment of the invention can be provided that the control body is annular. Thus, ends on the rege body, which would possibly have to be fixed, dispensable. Preferably, the control body is designed as an O-ring. Thus, an available standard component is usable.

In one embodiment of the invention it can be provided that the main body is composed of at least two parts, in particular wherein the at least two parts are positively, non-positively and / or materially and / or non-destructively releasably connected. Thus, the control body, especially if it is annular, easily inserted between the parts and held there in its position of use.

Alternatively or additionally, it may be provided that the base body is formed in one piece. Thus, a mounting is simplified. In particular, in this case, the receptacle may be at least partially axially open on one side. Thus, the control body already described is simply inserted into the receptacle. In this case, the control body used can be axially secured by a retaining element. It is thus a fall protection pictured, which simplifies the installation of the insert at the site.

In one embodiment of the invention can be provided that a connecting portion between the at least two parts passes through the control body. Thus, the control body is simply durable in the radial direction.

In one embodiment of the invention can be provided that describe the at least two parts with their outer dimensions a common cylinder jacket. Thus, a constant inner diameter of a tubular portion is well exploitable.

In one embodiment of the invention it can be provided that an at least partially axially acting sealing surface is formed on a downstream side. The advantage here is that a liquid leakage through the inclusion and bypassing the amount control are easily avoidable. Preferably, the sealing surface is completely aligned radially, thus, for example, has a surface normal, which is aligned parallel to the longitudinal axis of the insert and / or to the insertion of the insert. Thus, the sealing surface can be formed, for example, as a circular disk, through the opening of which flows the volume-controlled water. But there are also tapered sealing surfaces or generally a taper descriptive sealing surfaces can be formed, in which only a part, ie a component, a contact force is axially aligned.

In one embodiment of the invention can be provided that an outer diameter of the outer surface, in particular the already mentioned outer diameter is at most 8mm. Thus, very small flow regulator can be manufactured, which show a good control behavior. It is particularly favorable if the outer diameter is at most 6 mm. Thus, particularly small installation dimensions are achievable.

The stated object is achieved according to the invention alternatively or additionally by the features of the sibling, directed to a use claim. In particular, therefore, to achieve the stated object, a use of a sanitary insert according to the invention, in particular as described above and / or after one of the directed to an insert claims proposed, wherein the insert is inserted into a tubular portion, wherein an inner wall of the tubular closure as radially outer completion of the recording of the control body is used. Thus, in the installation situation, the receptacle in which the control body is arranged is closed radially on the outside by the receiving tubular section. An additional space for a radial conclusion about the control body by a housing of the insert, which would radially increase the insert or would require an unfavorable reduction of the control body is thus avoidable. The female tubular portion can thus take over a housing-forming function to complete the control body.

In one embodiment of the invention, it may be provided that an at least partially axially acting sealing surface, in particular the already mentioned sealing surface, seals off between the insert part and the tubular section downstream of the receptacle. The advantage here is that an outside bypassing the control gap, which would adversely affect the control behavior, is avoidable. In particular, it can be provided in this case that the sealing surface rests against a radially inwardly projecting collar on the tubular portion. The tubular portion may thus be provided with a collar which holds the insert part at its place in the section even at high pressures. It is thus achievable an automatic reinforcement of the seal on the sealing surface.

The invention will now be described in detail with reference to an embodiment, but is not limited to the embodiment. Further exemplary embodiments result from a combination of the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

• 6 three views of another insert according to the invention and
• 7 three views of another insert according to the invention.

The 1 to 4 show a sanitary insert according to the invention 1 in different representations. The insert part 1 has a substantially cylindrical body 2 on, which has a radially oriented outer surface 3 having. The main body 2 continues to have a rotating recording 9 on, in which an approximately O-ring-shaped rule body 4 is used. The recording 9 is at least in one of the rule body 4 assumed axial section 12 radially open to the outside.

Here is the outer diameter 10 of the rule body 4 on the outside diameter 11 the outer surface 3 Voted. That means the outside diameter 10 of the rule body 4 preferably smaller than the outer diameter 11 the outer surface is. In particular, at most 20%, preferably at most 10% smaller, that is as close as possible to, but below, the outer diameter of the control body 2 ,

The insert part 1 has an inflow side 21 through the water in the insert 1 flows in, and a downstream side 20 through which water leaks up.

As in particular in 3 can be seen, the body indicates 2 a regulator core 5 on, coaxial in the center of the body 2 is arranged. The controller core 5 has radially outside a controller profile 6 on that together with the coaxial to this regulator profile 6 arranged control body 4 a control gap 7 Are defined.

The rule body 4 consists of an elastic material, so that the opening cross-section 8th of the rule gap 7 by a pressure-dependent admission of the control body 4 is changeable.

The main body 2 is formed in two parts in the example, so that a mounting can be done easier. In particular, the two parts can be positively, positively and / or materially connected, so generally not non-destructive releasably connected. Thus, the rule body 4 , Especially if it is annular, easily inserted between the parts and held there in its position of use. A first part 17 is in the example with a second part 18 via a connecting section 19 connected to the regulator body 5 penetrates axially. Here is the second part 18 locking elements 26 on that in the first part 17 intervene and thus create a detachable connection. The locking elements 26 may alternatively or additionally to the first part 17 be educated.

The already described outer surface 3 can do this on the first part 17 and / or the second part 18 be educated. In the present embodiment, the two outer surfaces are aligned 3 and thus form a common, two-part outer surface 3 with a shape of a cylinder jacket

In 5 is now an inventive sanitary insert 1 in a tubular portion 23 used. The inner wall 24 of the tubular portion 23 serves as a radially outer completion of the recording 9 of the rule body 4 , Thus, in the installation situation, the recording 9 , in which the control body 4 is arranged, radially outwardly through the female tubular portion 23 completed. An additional space for a radial termination around the control body 4 through a housing of the insert 1 which radially increase the insertion part 1 or an unfavorable reduction of the control body 4 would require, is thus avoidable. The female tubular section 23 thus assumes a housing-forming function to complete the rule body 4 , In practice, the tubular section 23 For example, a part of a sanitary fitting, a pipe system or the like.

In the example, the tubular section 23 a partially axially acting sealing surface 22 on that between the insert part 1 and the tubular portion 23 downstream to the recording 9 seals. The advantage here is that an outside bypassing the control gap 7 , which would adversely affect the control behavior, is avoidable. In particular, it can be provided that the sealing surface 22 on a radially inwardly projecting collar 25 at the tubular portion 23 is applied. The collar 25 holds the insert part 1 even at high pressures in its place in the section 23 , It is thus an automatic reinforcement of the seal on the sealing surface 22 reachable.

At the inflow side 21 has the insert part 1 a sealing element 15 on, which is the outside bypassing the control gap 7 also on the inflow side 21 prevented. The sealing element 15 is by a over the Au0enfläche 3 radially projecting sealing lip 16 formed with the inner diameter 14 of the section 23 interacts.

6 shows in clockwise right below a view from below, so on the downstream side 20 , bottom left, a view from above, so on the inflow side 21 , and at the top left an axial section along the cutting plane SS. Constructively and / or functionally identical to the preceding embodiments identical or similar components and functional units are denoted by the same reference numerals and not described separately again. The remarks to the 1 to 5 therefore apply to 6 corresponding. In particular, the insert part after 6 in the tubular section 23 from 5 be set.

The embodiment according to 6 differs from the preceding embodiment at least in that the basic body 3 is formed in one piece or in one piece and that the recording 9 in the axial direction on one side, in particular against a flow direction, partially open.

Instead of the locking elements 26 indicates the basic body 2 retaining elements 27 on, which - as here in the example - can be tongue-shaped and the rule body 4 axially, for example by - as shown - and reach behind him. The sealing element already described for the previous embodiment 15 - Also here as an example as circumferential sealing lip 16 executed - is here at the downstream end of the body 2 , ie in the flow direction behind the control body 4 arranged. It seals and holds the body 3 in the tubular section 23 safe against falling out against the direction of flow. About an example pin-shaped removal element 28 is the insert part 1 with a tool, such as with a pair of pliers, used and / or removable.

The outer surface 3 is thus as a simple, contiguous cylindrical surface below the recording 9 educated.

7 shows in clockwise right below a view from below, so on the downstream side 20 , bottom left, a view from above, so on the inflow side 21 , and at the top left an axial section along the cutting plane SS. Constructively and / or functionally identical to the preceding embodiments identical or similar components and functional units are denoted by the same reference numerals and not described separately again. The remarks to the 1 to 6 therefore apply to 7 corresponding. In particular, the insert part after 7 in the tubular section 23 from 5 be set.

Also in this embodiment, the main body 3 made in one piece or in one piece. The recording 9 is here now completely open in the axial direction open on one side, so that the control body 4 easy in the recording 9 can be used.

The rule body 4 - and possibly also the basic body 3 - Is / are in this case axially secured, for example by means not shown in the tubular portion 23 such as a locking ring, a lock nut, radial screws or pins or the like.
