DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) FIGS. 1A and 1B show a sanitary fixture, which is denoted in its entirety by 1, with an outer sleeve 2 which is set up in a manner known per se for installing in the output of a fitting or at a different location of a water-conducting system.

(8) A throughflow element 3 which is likewise sleeve-shaped is inserted into the outer sleeve 2.

(9) Throughflow openings 4 are formed in the throughflow element 3.

(10) In the exemplary embodiment shown, ten throughflow openings 4 distributed along a circumference are formed. In further exemplary embodiments, a different number of throughflow openings 4 are formed.

(11) The throughflow openings 4 are oriented radially with respect to a longitudinal axis 5 of the fixture 1.

(12) The throughflow openings 4 are releasable and at least partially closable by a covering element 6.

(13) The covering element 6 here is manufactured from a temperature-sensitive material.

(14) FIG. 1A and FIG. 2A show the covering element 6 in a state in which the throughflow openings 4 are released.

(15) FIGS. 1B and 2B show the covering element 6 in a state in which the throughflow openings 4 are closed.

(16) FIGS. 1A and 1B show, from the top downward, the fixture 1 on the approach flow side, in a partially sectioned, three-dimensional perspective view and on the discharge flow side.

(17) Covering surfaces 7 which are coordinated with the throughflow openings 4 are formed radially on the outside of the covering element 6. Said covering surfaces 7 interact with the throughflow openings 4 in order to release or to close the throughflow openings 4 depending on the state of the covering element 6.

(18) The temperature-sensitive material of the covering element 6 has the effect here that, in a first temperature range, the state according to FIG. 1A, i.e. the releasing state, is taken up, whereas, in a second temperature range, for example a higher temperature range, the closing state according to FIG. 1B is taken up.

(19) It is apparent from FIGS. 1A and 1B and FIGS. 2A and 2B that the covering element 6 is formed as a single piece. The covering element 6 is formed as a spirally curved tongue 16.

(20) The temperature-sensitive material of the covering element 6 here causes a variation in the shape of the covering element 6 depending on the temperature, said variation in the shape being visible in FIGS. 2A and 2B, for example, at a changed circumference of the covering element 6.

(21) In the releasing state of the covering element 6 according to FIGS. 1A and 2A, the tongue 16 forms a gap 18. Water can flow through the gap 18 into the throughflow openings 4. In the closing state of the covering element 6 according to FIGS. 1B and 2B, the gap 18 is closed, and the covering element 6 closes the throughflow openings 4.

(22) In the presented exemplary embodiment, the covering element 6 is manufactured by a thermostatic bimetal or has such a thermostatic bimetal.

(23) The effect achieved by this is that the bending of the covering element 6 is temperature-variable, and therefore the covering element 6 has a larger circumference in FIG. 2B than in FIG. 2A.

(24) The covering element 6, with the covering surfaces 7 thereof formed on the covering element 6, therefore bear flat against the throughflow openings 4 in order to close same.

(25) The sanitary fixture 1 has a main flow path 8 through which the water flows in every state of the covering element 6. It is apparent that the covering element 6 is arranged on the approach flow side of the throughflow openings 4.

(26) A functional unit 9, which is known per se and is shown here as a volume regulator unit, is arranged in the main flow path 8. In further exemplary embodiments, this volume regulator unit can be replaced or supplemented, for example, by a jet-shaping unit and/or a jet aeration unit or by another functional unit.

(27) The possibility of a bypass to this main flow path 8 and the functional unit 9 is provided by the releasable throughflow openings 4.

(28) The throughflow openings 4 are arranged radially here outside the main flow path 8 of the sanitary fixture.

(29) The covering element 6 annularly surrounds said main flow path 8 of the sanitary fixture 1 radially on the outer side.

(30) The covering element 6 is fastened at a fixed end 10, the inner end of the spiral shape, to a housing part 11.

(31) The spirally curved covering element 6 is supported at the free end 12 thereof on the throughflow element 3.

(32) Overall, the covering element 6 is therefore arranged in a cup-shaped receptacle 17 which is formed by a round receptacle wall 13 of the throughflow element 6 and a base 14.

(33) The base 14 of said cup-shaped receptacle 17 supports the covering element 6 and bears the stub-shaped housing part 11.

(34) The base 14 is fixedly connected to the outer sleeve 2.

(35) The receptacle wall 13 therefore forms supports 15 for the covering surfaces 7 for closing the throughflow openings 4. In the releasing state of the covering element 6, the gap 18 is therefore formed between the tongue 16 and the supports 15.

(36) FIGS. 3A and 3B and FIGS. 4A and B show a further exemplary embodiment according to the invention of a sanitary fixture 1. Components and functional units which are similar or identical functionally and/or structurally to the exemplary embodiment according to FIGS. 1A and 1B and FIGS. 2A and 2B are denoted by the same reference numbers and are not described separately once again. The statements with regard to FIGS. 1A and 1B and FIGS. 2A and 2B therefore apply correspondingly to FIGS. 3A and 3B and FIGS. 4A and B.

(37) FIG. 3A and FIG. 4A both show the sanitary fixture 1 with a covering element 6 which is in a releasing state. Water can flow through the throughflow openings 4 in this state. The right halves of the drawing in each case show the covering element 6 in a closing state. In this state, the throughflow openings 4 are closed.

(38) The exemplary embodiment according to FIGS. 3A and 3B and FIGS. 4A and B differs from the exemplary embodiment according to FIGS. 1A and 1B and FIGS. 2A and 2B in that the throughflow openings 4 are oriented axially, i.e. parallel to the longitudinal axis 5 of the fixture 1.

(39) The upper third of FIGS. 3A and 3B shows the view on the discharge flow side, the center shows a partially sectioned perspective view and the lower third shows the view on the approach flow side. The covering element 6 is therefore arranged on the approach flow side of the throughflow openings 4.

(40) The covering element 6 has tongues 16 which, in the closing state of the covering element 6, are flat and close the throughflow openings 4.

(41) At the free ends 12, a respective covering surface 7 is formed in a manner matching the clear opening of the throughflow opening 4, and therefore a throughflow opening 4 is closable by each tongue 16. At the fixed ends 10 of the covering element 6, the tongues 16 are connected to one another.

(42) In the closing state of the covering element 6 according to FIGS. 3A and 3B and FIGS. 4a and 4B, the covering element 6 rests against the flat support 15 in which the throughflow openings 4 are formed.

(43) In the releasing state of the covering element 6, the tongues 16 are bent upward counter to the force of the flowing water. The tongues 16 together with the supports 15 form gaps 18 through which the water can flow into the throughflow openings 4.

(44) FIGS. 3A and 3B and FIGS. 4A and 4B show a sanitary fixture in which nine throughflow openings are formed. In further exemplary embodiments, other numbers and/or shapes of throughflow openings 4 are formed.

(45) In the described exemplary embodiments and further exemplary embodiments, the throughflow openings 4 are of slot-shaped design. In this connection, the opening cross section of the throughflow openings 4 can increase away from the covering element 6, as is apparent in FIGS. 3A and 3B.

(46) In further exemplary embodiments, the covering elements 6 are arranged on the discharge flow side of the throughflow openings 4.

(47) In the case of the sanitary fixture 1, it is proposed to form at least one covering surface 7 on a covering element 6 made of a temperature-sensitive material, with which covering surface 7 at least one throughflow opening 4 of a throughflow element 3 is releasable and is at least partially closable depending on the temperature.
