Throttle device to keep the flow rate constant
of a fluid

The innovation concerns a throttle device according to the preamble of ti

Protection claim 1. $

Throttle devices of the type in question for water heaters are in || '

known in a wide variety of designs (e.g. DE-AS 10 49 176). In the | f

Such a throttle device usually consists of an elastic water jf

flow control body, a seal and a control body in front of |

switched sieve body. The individual components of this throttle device

are connected to the separate feed pipe of the flow heater with the help of a j

connecting union nut held together. The assembly of the \

Individual components of the known throttle device does not require a f.

insignificant expenditure of time and reduces the operational safety with a j

incorrect assembly that cannot be ruled out. I.

The task of the innovation is therefore the throttle device of the type mentioned j |

to be designed so that the effort for assembly and disassembly in;,

I Faults are reduced and incorrect assemblies are practically eliminated |

will. |:

I The solution to this problem according to the innovation is the characterizing part | ί

of the protection claim 1 can be found.

Appropriate further refinements of the subject of the innovation are in specified in the subclaims.

The innovation creates a simple constructional throttle device created that is inexpensive to manufacture and can be installed in a time-saving and operationally reliable manner.

Embodiments of the innovation are shown in the drawing and are described in more detail below on the basis of these. 10

The drawing shows the individual components of the throttle device in disassembled state.

With 1 is the part of a water inlet pipe for a not shown hydraulically controlled water heater, which has a beaded edge 2. There is a union nut on the water inlet pipe 1 attached, which receives the beaded edge 2 of the water inlet pipe 1 in sees. A seal 5 as well as a screen body 6 and the seat 7 of a water volume control body 8 are combined to form a one-piece assembly unit 4. The counterpart 9 to the water inlet pipe 1 has an external thread 10 for screwing on the union nut 3 and the assembly unit 4 and the Water quantity regulating body 8 in receiving chamber 11. In the scope of the seat 7 for the water quantity regulating body 8 are spaced slots 12 formed, which a resilient holder (receptacle) of the water quantity regulating body 8 ensure.

In the embodiment according to FIG. 2, ^{a central pin 13 protruding from the assembly unit 4 'is integrally formed on the strainer body 6 1} , onto which the water quantity regulating body 8, which is provided with a corresponding blind hole 14, can be plugged. The plug-on pin 13 is by providing a
