  • the shaft (40) has, in addition to the receiving space (41) into which the writing tip (1) is screwed in, a storage space (42) for the ink, ink or for another liquid application medium, and thus simultaneously provides the writing medium storage (cartridge, Cartridge or the like) in total.
  • the housing (1) with its peripheral surface sealingly inserted into the receiving space (41) has a circumferential outer channel (66) in its outer surface, a spiral equalizing channel (64) on the inside and a connecting channel (65) at the rear end and thus contains the essential elements of the compensation system.
  • the tube insert (20) is axially sealed in the bore of the housing (1 ') and is fully assembled with the fixed closure (30) sealingly against a sealing stop (43).
  • the closure (30) thus prevents direct writing medium entry into the compensation system and also seals its connecting channel (65) from the rear in a sealing manner.
  • the essentially cylindrical bore (73) has support stops (32) for the spring (71) at the rear and then continues as an inlet bore (31) provided with capillary inlet channels (59) to the rear end.
  • a circumferential jacket preferably a capillary ring channel (63), from which a connection channel (62), preferably designed as a non-capillary bore or a rectangular opening, completely penetrates the wall of the tube insert and in the area of the bore (73) arranged in the bore (73).
  • Axial to the storage space (42) continuous, non-capillary air channel (61) opens into the interior of the writing tip (1).
  • the core insert (10 ') has a rear _ here cylindrical, but alternatively also conical formable _ pin (13), a cone (12), a subsequent cylinder piece (14) and a fixed needle (11).
  • the inflow system essentially consists of the preferably capillary inlet space (51) formed by the inlet bore (31) and the pin (13), into which the capillary inlet channels (59) open radially, from which the cylindrical bore (73 ) and the pin (13) formed, the spring (71) receiving, usually non-capillary interior (52), from the / increasing capillarity cone space (53), which results from the annular space formed by the cylindrical bore (73) and the casing of the cone (12), from the capillary holding space (54) between the cylinder piece (14) and bore (73), from the intermediate storage space (55), partially penetrated by radial inflow channels (58), and from the write storage space (56) and the writing space (57).
  • the intermediate storage space (55), the write storage space (56) and the writing space (57) are in this case designed as annular spaces with increasing capillarity towards the writing body (1 ⁇ ) through stepped bores in the housing (1 ′). and in the writing tube (1 ⁇ ) and the outer surface of the axially movable with the core insert (10 '), the writing tube (1 ⁇ ) slightly protruding on the end of the needle (11).
  • the lock (30) which is centered and possibly sealed in the fitting bore (44) of the barrel (40) and a centering collar (72) provided with an air passage (67), serves on the one hand to securely fix the writing tip (1) in the barrel (40) ), which is centered on the wall of the receiving space (41) of the shaft (40) at the front and, if necessary, also seals.
  • connection channel (62) connecting the inflow and the compensation system practically opens into the region of the highest capillarity of the cone space (53) and also the subsequent, high one Capillarity, holding space (54) still touched.
  • the core insert (10 ') which is made of plastic here, can also be arranged so as to be freely movable axially and possibly made of metal, and possibly. otherwise have a mass weight.
  • the compensation system is particularly effective if it consists of an inner or upstream compensation channel (64) running in a spiral or meandering shape and an external channel (66) which is optionally connected via a connection (65) and is also preferably of a spiral or meandering configuration.
  • the compensating channel (64) can also continue axially beyond the connecting channel (62) and thus form a buffer zone (68) which may become additionally effective and which either enters the intermediate storage space (55). opens out or only as a residual channel closed on one side takes up a small amount of writing material if necessary.
  • FIGS. 2 to 4 show the axial course of the individual zones and areas and their cross sections.
  • the closure (30) with the inlet bore (31) and the inlet channels (59) can first be seen (according to FIG. 2) via the storage space (42).
  • the axially continuous non-capillary air channel (61) opens into the inlet space (51) formed by the pin (13) and the inlet bore (31).
  • Figure 3 also shows the attached to the housing (1 ') spiral outer channel (66), the also spiral compensating channel (64), the conical space (53), the tube insert (20) and the spring (71) while from Figure 4 still with an air passage (67) provided centering collar (72), the radially penetrating the tube insert (20) and into the ring channel (63) opening connection channel (62), the capillary holding space (54) and the cut cylinder piece (14) can be seen.
  • the writing tip (1) essentially has the writing tube (1 ⁇ ) firmly inserted into the housing (1 '), an inlet channel (59) recognizable by the closure (30), an outer channel (66) spiraling and gradually offset and a centering collar (72) with an air passage (67).
  • connection threads (75) can serve to fasten a closure cap, not shown here.
  • the writing tube (1 ⁇ ) is pressed into the front zone of the housing (1 ').
  • FIG. 7 shows the tube insert (20), the annular channel (63) rotating on the outer jacket (21), the connecting channel (62) radially penetrating the wall in this and in the axially continuous air channel (61), the cylindrical bore (73) at the back against the inlet bore (31) delimiting support stop (32) and the closure (30) provided with inlet channels (59) can be seen.
  • the core insert (10 ') according to Figure 8 consists essentially of the needle (11) inserted into the cylinder piece (14) or the cleaning wire customary in tube writing instruments, the cone (12) and the pin (13). It can preferably be made of thermoplastic or metal, ceramic or the like. be made.
  • the writing tip (1) according to FIG. 9 also equipped with a writing tube (1 ⁇ ) and screwed into a holder (40) has a core insert (10 ⁇ ) designed as a drop weight with a pin (13) and a needle (11) and a closure (30).
