DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(22) Differently designed outlet orifices 5, 8, 11, 14, 17 are illustrated in FIGS. 5 to 19. The outlet orifices 5, 8, 11, 14, 17 are sleeve-shaped and have an outer thread 2 on their outer circumferential wall 1. The outlet orifices 5, 8, 11, 14, 17 can be screwed via their outer thread 2 into an inner thread 3. The inner thread 3 is provided on an inner circumferential wall 4, which defines the outlet opening 6 of the water outlet of a sanitary outlet armature 7.

(23) So as to form a homogeneous, non-splash and possibly also softly effervescent, that is to say aerated, water jet, an insert cartridge 9 can be inserted and/or screwed into the sleeve interior of the sleeve-shaped outlet orifice 5, 8, 11, 14, 17 and has a jet regulator and, where necessary, also a sieve attachment 10 on the inflow side and/or a flow rate regulator possibly arranged therebetween.

(24) The outlet armature 7 provided for the outlet orifices 5, 8, 11, 14, 17 according to FIGS. 5 to 19 is illustrated in greater detail in FIGS. 1 and 2. It is clear from FIGS. 1 and 2 that the outlet armature 7 has an armature body 12, which carries the outlet opening 6 in its outer circumference. Whereas the previously known outlet armatures 7 corresponding to the prior art and illustrated in FIGS. 3 and 4 previously had an outlet opening 6, which has an annular shoulder or annular flange 15 referred to as a jet regulator bridge in its portion of the outlet opening 6 facing a water-guiding inner cavity 13 on the inflow side, the outlet armature 7 intended for the outlet orifices 5, 8, 11, 14, 17 has an outlet opening 6, which has a constant and shoulder-free clear opening cross section in its end region discharging into the inner cavity 13 of the outlet armature 7.

(25) It is clear from a comparison of the outlet orifices 5, 8, 11, 14, 17 illustrated in FIGS. 5 to 19 that these outlet orifices carry on their outer circumferential wall 1 a ring seal 18, which radially and/or axially seals between the outer circumferential wall 1 and the inner circumferential wall 4 of the outlet armature 7.

(26) The sleeve-shaped outlet orifices 5, 8, 11, 14, 17 are assigned to the outlet armature 7. The outlet orifices 5, 8, 11, 14, 17 have on their outer circumferential wall 1 the outer thread 2, with which the outlet orifices 5, 8, 11, 14, 17 can be screwed into the inner thread 3, which is provided on the inner circumferential wall 4 of the outlet armature 7 defining the outlet opening 6 of the water outlet. The outlet orifices 5, 8, 11, 14, 17, into each of which an insert cartridge 9 having a jet regulator can be inserted, carry on their outer circumferential wall 1 at least one ring seal 18, which radially and/or axially seals between the outer circumferential wall 1 of the outlet orifices 5, 8, 11, 14, 17 and the inner circumferential wall 4 of the outlet armature 7. Since the outlet orifices 5, 8, 11, 14, 17 are radially and/or axially sealed with respect to the inner circumferential wall 4 of the outlet armature 7 defining the outlet opening 6, the outlet opening 6 can also be incorporated into the outlet armature 7 with a constant clear inner diameter. Since, with the outlet armature 7 it is thus possible to dispense with an annular flange or annular shoulder on the inner circumferential wall 4 necessary to provide an axial seal, the outlay associated with the production of the outlet armature 7 is considerably reduced. In this case, the insert cartridge 9 is held with the aid of one of the outlet orifices 5, 8, 11, 14, 17 in the water outlet of the outlet armature 7, which clearly and comprehensibly indicates the replaceability of this insert cartridge 9. Since the outlet orifices 5, 8, 11, 14, 17 are at least also radially sealed with respect to the outlet armature 7 with the aid of the at least one ring seal 18, an excessive tightening of the outlet orifice in the outlet opening also is not necessary and should not be feared, as would often incorrectly be considered necessary with an axial seal of these components.

(27) In their outer circumference, the outlet orifices shown in FIGS. 5 to 16 have a circumferential groove 19, in which the ring seal 18 produced from resilient material is securely held. The insert cartridge 9 provided in the outlet orifices 5, 8, 11, 14, 17 is held there so as to be secured on either side in the axial direction. In this case, the insert cartridge 9 of the outlet orifice 5 illustrated in FIGS. 5 to 7 can be inserted into the outlet orifice 5 from the inflow side thereof as far as an insertion stop 20, which is formed in this case as an annular shoulder. The insert cartridge 9 of the outlet orifice 5 is held in the outlet orifice 5 so as to be secured between the insertion stop 20 and a retainer 21 that can be fastened releasably to the inner circumference of the outlet orifice 5. On its outer circumference, the retainer 21 has a resiliently deformable retaining ring 22, which engages releasably latchably with at least one latching protrusion 23 in a latching groove 24 in the inner circumferential wall of the outlet orifice 5. A ring seal 25 is provided between the insert cartridge 9 and the retainer 21 and axially seals the region between the insert cartridge 9 and the inner circumference of the outlet orifice 5. It can be seen in FIGS. 6 and 9 that the outlet orifices 5 and 8 can be screwed into the inner thread 3 in the outlet opening 6 until an annular flange 26, defining the groove 19, of the outlet orifice contacts an insertion stop 27 on the inner circumferential wall of the outlet opening 7.

(28) It can be seen in FIGS. 8 to 19 that, on their inner circumference, the outlet orifices 8, 11, 14, 17 carry an inner thread 28, into which an outer thread 29 provided on the outer circumference of the cartridge housing of the insert cartridge 9 can be screwed. In this case, the insert cartridge 9 in the case of the outlet orifices 8, 11, 14, 17 is screwed into the sleeve interior of these outlet orifices 8, 11, 14, 17 from the outflow side.

(29) In the case of the outlet orifices 8, 11, 17, the insert cartridge 9 can be screwed in from the outflow side of these outlet orifices as far as an insertion stop 16. The insertion stop 16 is formed as an annular shoulder or annular flange arranged on the inner circumference of the outlet orifices 8, 11, 17. It can be seen in FIGS. 8, 11 and 17 that the insertion stop 16 designed as an annular flange is arranged in the transverse plane of the outlet orifices 8, 11, 17 on the inflow side. Whereas the annular flange of the outlet orifice 11 merely delimits the screw-in or insertion path, a ring seal 40 is provided between the annular flange of the outlet orifices 8, 17 and axially seals the region between the outer circumference of the outlet orifices 8, 17 and the inner circumferential wall of the outlet orifice 8, 17.

(30) If FIGS. 11 and 14 are observed in greater detail, it is clear that an insertion stop 16 may also be provided on the outer circumference of the insert cartridge 9, is formed as an annular shoulder or annular flange, and in this case is arranged upstream of the ring seal 30 in the direction of flow. This insertion stop 16 is preferably arranged downstream of the outer thread 29, adjacent thereto, in the direction of flow.

(31) In the case of the outlet orifices 8, 17, the region between the insert cartridge 9 and the inner circumferential wall of the outlet orifice 8, 17 is axially sealed by means of the ring seal 40, which is fixed between the insertion stop 16 and the end face of the cartridge housing on the inflow side. By contrast, in the case of the outlet orifices 11, 14, this region is radially sealed by means of a ring seal 30, which is held on the outer circumference of the cartridge housing, where it is arranged in a circumferential groove 31.

(32) It can be seen from a comparison of FIGS. 5 to 19 that the outlet orifices 5, 8, 11, 14, 17 protrude beyond the outlet armature 7 via a partial region of their longitudinal extension on the outflow side. In this case, at least one tool engagement surface 32 for a rotary tool is provided on the partial region of the discharge orifices 5, 8, 11, 14, 17 protruding beyond the outlet armature. With the outlet orifices 5, 8, 11, 14, 17, this tool engagement surface 32 is formed as a spanner engagement surface arranged on opposite circumferential sides of the outlet orifice.

(33) On their outer circumference, the outlet orifices 8, 11, 14, 17 have an insertion stop 33, which is designed as an annular flange or annular shoulder and delimits the screw-in path of the outlet orifices 8, 11, 14, 17 into the inner thread 3. The outlet orifices 8, 11, 14, 17 can be screwed into the inner thread 3 of the outlet opening 6, until the insertion stop 33 contacts the outer edge, defining the outlet opening 6, of the outlet armature 7. Whereas, with the outlet armature 14, the ring seal 18 is held in the groove 19, which adjoins the insertion stop 33 on the outflow side, the ring seal 18 with the outlet orifice 17 is merely slid on as far as the insertion stop 33.

(34) In the case of the outlet orifices 14, 17 too, the ring seals 18 seal at least also radially. In this case, the ring seal 18 of the outlet orifice 17 is pressed into a phase, which defines on the outflow side the outlet opening 6 of the outlet armature 7 assigned to the outlet orifice 17, so that a radial and axial sealing effect is produced.
