Description

[0001] The invention relates to an interchangeable holder for throttle valves of various sizes in a fluid-carrying system, a fluid-carrying system, and a vehicle. Throttle valves and their use in fluid-carrying systems for changing the flow resistance and thus for controlling and regulating the flow of a fluid are well known. Currently, throttle valves are primarily used in hoses so that, in the event of a change, only the affected throttle valve can be replaced. Installation in the same hose using a pressure press is then possible. When a throttle valve is used in an assembly or in a single plastic component, replacing the throttle valve also means changing or replacing the tool, if not the entire hose. This is complex and costly.

[0002] US 11,112,808 B2 describes a flow restrictor for liquids, wherein a throttle valve is inserted into the connection area of ​​two pipe sections and held by means of a sleeve.

[0003] DE 198 33 899 C2 describes a combined component consisting of a throttle valve and a check valve, which is inserted into an elastic hose and secured by means of an external retaining clip. The check valve can be clipped into the throttle valve or attached to it by means of a snap connection.

[0004] Reference is also made to EP 0 509 344 B1 as a further state of the art.

[0005] The object of the invention is to provide an alternative fastening option for throttle valves in fluid-carrying systems, as well as a fluid-carrying system and vehicle.

[0006] The problem is solved by a changeable holder with the features of claim 1, by a fluid-guiding system with the features of claim 5, and by a vehicle with the features of claim 10. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0007] The interchangeable holder according to the invention for throttle valves of various sizes in a fluid-carrying system, particularly in a vehicle, is designed such that it can be removed from the system and the throttle valves can be exchanged when removed. With the interchangeable holder according to the invention, different throttle valves can be used in the system. Advantageously, only the interchangeable holder is removed from the system for replacement and then reinserted. Within the scope of the invention, the term "throttle valve" is understood as a generic term for any components that alter flow resistance, for example, valves, capillaries, nozzles, or orifices. The fluid-carrying system can contain both water and air.Furthermore, the interchangeable holder according to the invention can advantageously be used both in hoses made of a flexible material and in pipes made of a harder and inflexible material such as hard plastic, polymer, or similar materials. For the sake of simplicity, the term "hose" will be used consistently in the following text, but this term is not to be understood restrictively; it also includes pipes.

[0008] It is provided that fastening means are designed for securing the interchangeable holder in a hose of the fluid-carrying system. Preferably, the fastening of the interchangeable holder can be released and re-secured without tools. Therefore, the fastening means are preferably operable without tools for securing and releasing the interchangeable holder in the hose. Furthermore, preferably, the interchangeable holder is arranged in an end region, in particular a hose fitting, or another easily accessible area of ​​the fluid-carrying system.

[0009] The fastening means can be designed, for example, as an external thread for screwing the quick-release holder into the hose and / or as a frictional locking element to create a frictional connection between the quick-release holder and the hose. For a frictional connection between the quick-release holder and the hose, the contact surfaces between these components are advantageously designed to be frictionally tight or rough. For example, the quick-release holder may have serrations or other irregularities, or a coating with a particularly high-friction material. The aforementioned list of fastening means is not exhaustive. Other types of fastening means and configurations of the fastening are also within the scope of the invention.

[0010] It is further provided that retaining / exchangeable means are present and designed to hold the throttle valves in the interchangeable holder, and which also enable easy exchange of the throttle valves in the interchangeable holder. According to the invention, the interchangeable holder is compatible with throttle valves of various sizes. Preferably, the interchangeable holder has retaining / exchangeable means that, on the one hand, enable easy, quick, and preferably tool-free exchange of the throttle valves and, on the other hand, ensure secure fastening of the respective throttle valve in the interchangeable holder. For example, the retaining / exchangeable means can be designed as a simple clip system, a bayonet fitting, or the like.

[0011] Throttle valves of different sizes usually differ at least in their fluid-permeable inner diameter, and depending on the embodiment, also in their outer diameter, which should be suitable for mounting in a hose or the like, or in the interchangeable holder according to the invention. In a simple embodiment, the interchangeable holder, or rather the holding / exchange means, are designed to mount different throttle valves with the same outer diameter. Advantageously, it is then not necessary to adapt the holding / exchange means to the different throttle valves. In another embodiment, the interchangeable holder, or rather the holding / exchange means, are designed to mount different throttle valves with different outer diameters. The ability to mount throttle valves with different outer diameters makes the interchangeable holder significantly more flexible in its application.

[0012] The fluid-carrying system according to the invention, particularly in or for a vehicle, comprises at least one interchangeable holder according to the invention as described above. The advantages, advantageous embodiments, and effects mentioned above in connection with the interchangeable holder also apply to the system according to the invention.

[0013] It is also provided that fastening means are present in or on the hose and designed to secure the interchangeable holder. Preferably, the fastening means of the interchangeable holder are designed to be compatible with the fastening means of the hose, so that they advantageously work together. The fastening means of the system can, for example, be designed as internal threads and / or as friction-fit elements and / or as a type of sleeve with a cap. For example, the hose may have serrations or other irregularities or a coating with a particularly high-friction material. The aforementioned list of fastening means is not exhaustive. Other types of fastening means and configurations of the fastening are also within the scope of the invention.

[0014] One fastening option involves an internal thread in the hose and an external thread on the quick-release fitting. Another fastening option, using friction, requires either the hose or the quick-release fitting, or both components, to have frictional locking elements, such as serrations or a coating. A further fastening option uses a type of sleeve with an external thread and a removable cap. This fastening element, or sleeve, can be screwed into the hose via the internal thread. The quick-release fitting with the throttle valve can then be positioned inside the sleeve within the hose. Finally, the sleeve can be closed with the cap. The cap is preferably annular with a central opening for fluid flow, allowing fluid to pass through the throttle valve.

[0015] It is advantageous for the replacement holder to be located in a hose fitting or another easily accessible area of ​​the system. This allows for easy removal of the replacement holder from the hose for replacing the throttle valve.

[0016] The vehicle according to the invention has a fluid-carrying system as described above. The advantages, advantageous designs, and effects mentioned above in connection with the interchangeable holder or the fluid-carrying system also apply to the vehicle according to the invention.

[0017] The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the figure description and / or shown in the figures alone, can be used not only in the combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments that are not explicitly shown or explained in the figures, but which can be derived and generated from the explained embodiments by separate combinations of features, are also to be considered as encompassed and disclosed by the invention.

[0018] Further advantages, features and details of the invention will become apparent from the claims, the following description of preferred embodiments, and the drawings. These show: Fig. 1 a simplified schematic representation of a section of a fluid-carrying system according to the invention with a change holder with throttle valve in a first embodiment, Fig. 2 a simplified schematic representation of a section of a fluid-carrying system according to the invention with a change holder with a throttle valve in a further embodiment., and Fig. 3 a simplified schematic representation of a fastening device designed as a cover made of Fig. 1 in a top view and a cross-section.

[0019] Fig. 1 and Fig. Figure 2 shows a simplified schematic representation of a section of a fluid-carrying system according to the invention, comprising a changeover holder 30 with a throttle valve 40 in two different embodiments. For clarity, only a section of the fluid-carrying system is shown, namely a pipe 20 with a pipe socket 21, to which a hose 10 is attached. The changeover holder 30 with the throttle valve 40 is arranged in the pipe socket 21. The changeover holder 30 is designed as a kind of ring or inner sleeve, inside of which the throttle valve 40, designed as a simple orifice, is held. The Fig. 1 or Fig. The two embodiments shown differ in the way the change holder 30 is attached to the pipe socket 21.

[0020] According to Fig. 1. The changeover holder 30 has a multitude of friction teeth on its outer surface, or rather its contact surface with the pipe fitting 21, while the inner surface of the pipe fitting 21, or rather the contact surface 32 of the pipe fitting 21 with the changeover holder 30, is a rough and high-friction surface, so that a frictional fit is formed between the pipe fitting 21 and the changeover holder 30 to hold the changeover holder 30 in position. The changeover holder 30 can be easily pressed into and removed from the pipe fitting 21.

[0021] According to Fig. 2. The interchangeable holder 30 is fastened in the pipe stub 21 by means of a fastening element designed as a sleeve 26. The pipe stub 21 has an internal thread 23, while the sleeve 26 has a corresponding external thread 31. The sleeve 26 is screwed into the internal thread 23. The interchangeable holder 30 is simply inserted into the sleeve 26. Additionally, a ring-shaped cover 24 is provided, which can also be screwed into the internal thread 23. The interchangeable holder 30 is held in position in the sleeve 26, particularly by the cover 24.

[0022] To replace the throttle valve 40, the hose 10 is first removed from the pipe fitting 21, and then the replacement holder 30 is removed from the pipe fitting 21. With the replacement holder removed, the throttle valve 40 can be replaced and, using the replacement holder 30, pressed back into the pipe fitting 21 or inserted into the sleeve 26. In both embodiments, the throttle valve 40 has the same outer diameter 41 and differs only in the size of the inner diameter 42.

[0023] The Fig. Figure 3 shows the lid 24 according to Fig. 2 in a top view (left) and a cross-section (right). The cover 24 has two opposing recesses 25 in which an additional screw connection with the pipe fitting 21 can be installed.
