が完全に閉塞する危険が存在する。Although various displacement pumps are already known which operate according to the volume principle, a common drawback of these pumps is their intermittent delivery. Furthermore, there are already metering devices in which a certain chamber volume is filled with fluid and which, after being decoupled from the inlet, is connected to the outlet, into which the entire chamber contents flow or are flushed. This device is unsuitable for precise dosing of very small quantities. This is because the chamber volume cannot be reduced arbitrarily, and filling and emptying are difficult. Dosing can also take place by means of known constrictions which allow a constant throughflow depending on the pressure drop. However, the flow-through characteristics of such a constriction section will change drastically if the constriction edge becomes slightly rounded, even by washing or dirt. In the case of small flow volumes and therefore small choke cross sections, there is also a risk that the choke will become completely blocked by small particles entrained in the fluid.

能である。The object of the invention is to be able to precisely control the fluid even at minimal volumetric flow levels without activation sensitivity, and in this way to avoid the disadvantages of significant pulsations in the volumetric flow in a simple manner. The goal is to achieve reasonably priced portioned meals that can be avoided to the greatest extent possible. To solve this problem, according to the invention, t1 is always filled with fluid! At least one hollow chamber with an approximately constant volume receives a determined compressed volume in each case at one or more inlets with increased pressure and, after complete separation from the inlets, an even lower Taking full advantage of the compressibility of the medium to be dispensed by re-releasing the compressed volume absorbed from the inlet due to the expansion of the fluid when it continues to communicate with one or more outlets present at the pressure level. good. The volumetric flow achieved by the present invention can be extremely small for slightly compressible fluids. Since the hollow chamber is substantially larger than the expanded volume, there is actually a small activation sensitivity. If a number of hollow chambers are communicated with inlets and outlets staggered with respect to each other in time, an almost stable metering can be achieved without practically any extra structure and outlay. A further feature of the invention provides that the volumetric flow of the dosing device can be adjusted by the frequency with which the hollow chamber is communicated with the inlet and the outlet and by the pressure drop. having overlapping discs, one of which is stationary and provided with a through opening forming an inlet and an outlet, while the second disc is rotatable. or placed on the first disc in a rocking manner;
and has a hollow chamber in the form of a chamber that opens only in the first disk,
This hollow chamber can communicate alternately with the inlet and outlet of the first disk by a rotatable or rocking arrangement of the second disk.

。As the material of the disc, according to the invention, a ceramic material, such as aluminum oxide, is proposed, for example. This is because, in the case of a sealing surface made of this material, an undesirable sustained leakage flow from the inlet to the outlet can be practically completely prevented, so that the inlet is reliably isolated from the outlet when the hollow chamber is not in motion. It is. For less important applications, other materials can of course also be used, for example synthetic resins.

。As is clear from FIG. 1, the hollow chamber 1 of one disc is alternately communicated with the inlet 2 and outlet 8 of the other disc;
This can be done through rocking movements. According to FIG. 1a, the cavity is already filled with the medium to be metered. According to FIG. 1b, the hollow chamber 1 is in communication with an inlet 2 which is under high pressure. Thereby, a constant amount of fluid flows into the hollow chamber 1, depending on the compressibility of the fluid and the elastic expansion of the hollow chamber 1. Subsequently, the cavity 1 is closed to the inlet 2. This state is shown in FIG. 1C. Finally, according to FIG. 1d, the cavity 1 is communicated with an outlet at a lower pressure, and the fluid sealed in the cavity 1 expands for its removal.

ば、流体送りが円軌跡で行われる。In this case, only the expanded volume reaches the outlet 3, since the hollow chamber 1 remains full. According to the embodiment according to FIG. 2, the hollow chambers are communicated alternately with the inlets and outlets of the lower cutting disk by the rotational movement of the upper disk. In this case, an arbitrarily large number and relatively small hollow chambers are provided, unless the inlets and outlets are directly interconnected in accordance with the operating principle described.1. These hollow chambers can be rotated. According to FIG. 2, the fluid delivery therefore takes place in a circular trajectory.

A large number of hollow chambers can rotate (eight in this example).
, and multiple inlets and outlets can be used.

In this principle diagram, the fluid delivery also takes place by a rotational movement, and the number of inlets or outlets and hollow chambers are then not the same. This makes it possible to communicate all hollow chambers with the inlets and outlets with a chronological lag. For n inlets or outlets and n+i hollow chambers - n (
n+1) individual volumes are obtained; in the illustrated example according to FIG. 4, 20 individual volumes are obtained.

するとともできる。According to the invention, separate inlets are possible such that simultaneous dosing and mixing of various fluids can be carried out in the manner described above. The invention also allows the outlet to be connected separately to the various consumers.

このような設計により、種々の消費装置へ供給される流
体を一様に分配することができる。Such a design allows a uniform distribution of the fluid supplied to the various consuming devices.

- As already mentioned, the embodiment described and illustrated is only an example for implementing the invention, and the invention is not limited thereto. Within the scope of the basic idea according to the invention, there are still other possibilities with regard to the arrangement and construction of the hollow chamber and the inlet and outlet.
