  • This compound and the valve body or corresponding valves are coordinated so that when inserting the cartridge in the printer first the ink outlet, and then the B venting opening to be opened.
  • the seal is the same in the reverse manner, ie it is first the vent, and then the ink outlet closed.
  • the already mentioned flag is connected to a float which is movable along an approximately perpendicular to the bottom wall of the ink cartridge and the housing extending guide.
  • the float is annular and extends within the cartridge or the housing of the same around a rod or sleeve-shaped guide around.
  • the float is preferably formed like a sleeve.
  • the float is made of a material whose density is slightly smaller than the density of the ink.
  • a corresponding plastic material is used for the float.
  • the ink cartridge usually comprises a bottom, four side walls and a lid, wherein the flag connected to the float within a perpendicular to the bottom of the ink cartridge extending, formed in a side wall, in particular narrow end wall web and slot-like wall area following the level of a upper, near the lid in a lower, ground level position is movable. At least in the area of this web and slot-like wall area, the ink cartridge from a transparent or translucent material, in particular plastic, since this wall area protrudes into the aforementioned light barrier of the printer or the ink cartridge receptacle of the printer, so that the light barrier with the the float connected flag can interact in a conventional manner.
  • the attached drawing thus shows an ink cartridge 10 for an otherwise not shown ink jet printer with a ventilation opening 17 between the ink storage space 20 and environment 21, and with a Tintenauslador 11 in the bottom 13 of the housing 1 of the ink cartridge 10 associated valve 22, which in use in the printer against the action of an elastic element, here helical compression spring 6 from a closed position shown in the accompanying drawings in an open position, and vice versa, can be brought.
  • the ink outlet 11 associated with the valve 22 is associated with the ventilation opening 17 associated valve 23 such that when using the ink cartridge in the printer Tintenauslledge 11 and vent 17 are opened, or vice versa when removing the ink cartridge from the printer.
  • the mentioned coupling is such that when. Insert the ink cartridge into the printer, first the ink outlet 11 and then the air vent. 17 or vice versa when removing the ink cartridge from the printer.
  • Valve 22 associated with ink outlet 11 has a first valve body 18 cooperating with a port seal 11 disposed in ink port 11, while valve 23 associated with vent port 17 has a second valve body 19 cooperating with inlet port 5 disposed in vent port 17, both valve bodies 18 and 19 are rigidly connected to one another, namely by a rod-like connecting element in the form of a plunger 3.
  • an elastic element namely a helical compression spring 6 effective against the action of the valve body 18 from its closed position in the opening position can be brought or pushed, in accordance with arrow 24.
  • the helical compression spring 6 at a stage 25 of the plunger 3 z Wipe the two valve bodies 18 and 19 on the one hand and on the ventilation opening 17 delimiting wall, namely the lid wall of the ink cartridge or the housing thereof on the other hand supported.
  • the rod-like connecting element or the plunger 3 may have a circular, rectangular or cross-profile-like cross-section.
  • the latter cross-section is realized in the embodiment shown in the attached drawing.
  • the valve body 19 associated with the vent opening 17 includes an outer cylindrical piston portion 26 on the one hand and an inner, i.e., an outer, piston portion.
  • the aeration chamber 27 associated with the ink storage chamber 20 on the other hand the latter only after opening of the valve outlet 22 associated with the ink outlet 11 in operative position, i. B is achieved ventilation position.
  • the venting portion 27 is formed as a continuation of the piston portion 26, i. has the same outer diameter as the piston portion 26. However, it comprises at least one cross-sectional constriction extending over the length, in order to allow ventilation of the ink storage space 20 after appropriate movement of the piston portion 26 out of the inlet seal 5.
  • the ventilation section 27 has a cross-section-like cross-section which extends into the area of the helical compression spring 6.
  • a support ring 29 is arranged made of metal or plastic. This support ring also secures the inlet seal 5 within the vent 17 and prevents the inlet device 5 from migrating into the interior of the housing or into the ink storage space 20.
  • the filling of the ink cartridge 10 is otherwise carried out via an opening formed in the lid 2 Tintenhellö réelle 12, which is closed fluid-tight after being filled by a closure ball 8.
  • first valve body 18 defines a spherical zone.
