The invention relates to an ink feed for fountain pens with two axially one behind the other, Equalization chambers equipped with capillary cells. The invention is based on the object To create an ink circulation system in which the flow to the pen and from this for the writing unneeded ink makes a cycle, so that there is always an even ink release during use of the fountain pen is reached and a blob is completely excluded.

It has been shown time and again with fountain pens that the compensation chambers installed in the ink ducts are not large enough to completely absorb excess ink and compensate for fluctuations in air pressure to be able to, whereby the ink delivery of the fountain pen is too strong or irregular, quite apart from that from the risk of blobs.

With known pens, these disadvantages are further exacerbated by the fact that the compensation chambers usually move with each other when the fountain pens are filled Fill in ink so that they first have to be written blank to do their real task - namely Absorb excess ink - to be able to meet, at least initially not a regulated one Ink flow is possible.

Capillary incisions are already used in known holders; however, they are not in a Circulation system classified that allows a return of excess ink and with the Filling process a filling of the spaces provided for storage is avoided.

Two-part conductor systems with capillary incisions are also known. The items are, however not kept separate and are connected via longitudinal channels, whereby the filling of the Halters also takes place directly via the capillary systems. One circulation and one separate Air flow is not given. Other similar systems also lack that within the meaning of the invention decisive separation of the air channel from the rest of the capillary system.

The disadvantages given in these known systems are eliminated in an ink feed for fountain pens with two axially one behind the other, equipped with capillary cells compensation chambers, in which the invention consists in that the two compensation chambers arranged axially one behind the other are combined as special components in such a way that they form a compensation chamber include, the air channel is guided in its entire length separated from the ink channels and the out-ink feeder for fountain pens with two
Compensation chambers

Can be α 2 or suitable profiles of the pin 1, is through the air passage 8 vorderdes front part 1 or 2 and the sleeve-like side with the outside air and on the container side with the rear part 2, or such a front part V ink chamber 16 in connection. Through this formation or through the recesses of the front part 1 of the expansion chamber S, the spring 12 located in the front part 2 and the rear part 2 are air-Fig. 10, the two ink line parts can be balanced against pressure fluctuations. As soon as a radial twist is secured. Ink space 16 creates an overpressure, for. B. by the spring-side compensation chamber 3, which in the form of the heating and thus expansion of the air in capillary cells 6 over the entire length of this standing air, ink is not only cut into the front part 1, namely in the 45 ink channels 7, but Flanks also in the air channel 8 and in the underside, opens into the both pushes and drains, these collecting grooves arranged above the ink channels 7 shooting ink into the capillary cells 6 of the expansion 13 (see FIGS. 6 and 7). The collecting grooves 13 chamber5 arrives. Since there is no possibility of drainage on both sides to the outside or ink from this expansion chamber 5 can be formed by longitudinal grooves, and with its 5 ° spring 12 is given, the excess container-side leaks that are stored at this point by ink. At the same moment in which the outlet constriction has an increased capillary effect, the expansion chamber 5 together with the one in it open into a ring caoal 17. The running partial length of the air channel 8 is filled with ink, possibly occurring in the area of the front part 1, air can no longer get into the excess ink from the ink channels 7 into space 16. Through a 'resulting under the collecting grooves 13 and from these into the pressure in the ink chamber 16, e.g. by cooling the capillary cells 6 of the Ausgleidhskammer 3 further or consumption of ink, the in the Ausgleidhskammer 3 is diverted, which in turn stores the excess ink expansion chamber through stored excess tinite, whereby a uniform flow of ink from which is achieved in the inclined bore 20 of the air channel 8 of the spring 12 when writing. ^6o standing atmospheric air is pressed back into the ink-die-container-side compensation chamber 4 of the rear space 16. Only when the capillary hard part 2, which also has a certain number of capillary cells 6 of the expansion chamber 5, has been depleted of ink 6 around the entire circumference and has been emptied, a further air supply into the ink is arranged almost over the entire length of the rear part 2 possible. Through this process, the net. The capillary cells 6 of these chambers 4 engage 65 expansion chamber 5 all air pressure fluctuations in the ink channels 7 already running on the upper side of the rear part 2 and in the area of the front part 1 on the container side. An ink feed of the excess ink on and betetet execution of the compensation chamber 4 with axially ver the ink feed not.
