- FIG. 1 shows, in an axial sectional illustration, a sanitary installation component according to the invention denoted overall by 1.
- the built-in part 1 is formed with a tubular installation sleeve 2 as a cartridge, in particular Einsetzkartusche.
- An axis 3 of the installation sleeve 2 which is cylindrical in the example, defines a throughflow path 4 whose flow direction in FIG. 1 runs from top to bottom between an inlet 5 and an outlet 6.
- a functional unit 7 is formed in the flow path 4, which realizes in a manner known per se with a resistance body 8 - a 0-ring - a volume flow dependence of a volume control function.
- the resistance body 8 is pressed against a receiving part 9 to a different extent. to form a continuous cross-sectional area.
- the functional unit 7 counteracts the natural enlargement of the flow rate per unit time with increasing pressure by the fact that the cross-sectional area of the opening cross-section 10 is automatically reduced.
- another elastic shaped body is present to form a pressure-dependent cross-sectional area.
- the built-in part 1 according to FIG. 1 realizes, as described above, a volumetric flow dependence 11 through the curve to a temperature which is below a (lower) temperature threshold (see FIG. 4). It can be seen that the flow rate (per unit time) for pressures above 1 bar is almost constant and limited.
- the volumetric flow dependency 11 thus describes a quantity limiting function in which the flow resistance increases at least above an initial pressure of approximately 1 bar with increasing pressure.
- the asymptotic horizontal straight line which describes the limitation to values below a threshold value of six liters per minute, defines one Parameters of the realized volume flow dependency.
- volumetric flow dependence 12 in FIG. 4.
- the asymptotic curve that is the course for high pressures (in this case above an initial pressure of approximately 1 bar)
- This rising straight line describes a virtually or exactly pressure-independent flow resistance, for example a throttle.
- the volume flow dependence 12 thus qualitatively describes a throttle function.
- the quantity limitation of the volume flow dependency 11 is deactivated.
- the functional unit 7 in Figure 1 has an actuating element 13 which is arranged relative to a housing 14 and / or to the resistance body 8 movable or positionally variable.
- the adjusting element 13 can thus be adjusted or moved along a linear displacement path, which is aligned parallel to the axis 3, between the first actuating position of the actuating element 13 shown in FIG. 2 and the second actuating position of the actuating element 13 shown in FIG.
- the internals 1 realize the volumetric flow dependency 12 in FIG. 4.
- the built-in part 1 realizes the volume flow dependency 11 in FIG. 4.
- a drive unit 15 is formed in the internals 1.
- the drive unit 15 is temperature-sensitive and acts on the control element 13 according to its own temperature.
- FIG. 1 shows the drive unit 15 with a higher own temperature than in FIG. 2.
- a return spring 16 For returning the adjusting element 13 in the first setting position at a cooling of the situation shown in Figure 1 in the situation shown in Figure 2, ie below a threshold, a return spring 16 is provided. Water pressure, which acts on active surfaces, can support the return of the actuating element 13.
- the position according to FIG. 2 is assumed below a lower temperature threshold T ⁇
- the position according to FIG. 1 is assumed above an upper temperature threshold T >
- Lower temperature threshold T ⁇ and upper temperature threshold T > can be close to each other or even identical.
- the temperature thresholds T ⁇ , T > can separate the temperature range for cold water from the temperature range for hot water.
- the temperature threshold values T ⁇ , T > can be so close to each other that the transition from the volumetric flow dependency 12 to the volumetric flow dependency 11 takes place abruptly when the medium flowing through warms up (and vice versa during cooling).
- the adjusting element 13 is at a higher temperature of the drive unit 15 in the second setting position according to Figure 1, while the adjusting element 13 at a lower temperature of the drive unit 15 in the first setting position shown in FIG.
- the adjustment movement required for a change in position results from the fact that the drive unit 15 has a temperature-dependent expansion along the axis 3.
- a receiving chamber 17 formed in the interior of the drive unit 15 is filled with a temperature-sensitive medium 18, for example thermal wax.
- the medium 18 has the property of undergoing a phase change at a temperature between the lower temperature threshold T ⁇ and the upper temperature threshold T > (or at the temperature threshold when the lower temperature threshold and the upper temperature threshold coincide) and abruptly expands.
- the temperature-sensitive medium 18 expands upon heating of the drive unit 15 and acts on a movable chamber wall 19 of a piston 20.
- the piston 20 is thus pushed out of the receiving chamber 17 upon heating of the medium 18.
- the piston 20 is in operative connection with the actuating element 13 and acts on it, so that the actuating element 13 is transferred to the second actuating position according to FIG. 1 during a heating of the drive unit 15 via a threshold value from the first setting position according to FIG. 2 along a rectilinear adjusting movement.
- the change in position of the actuating element along the adjustment path is achieved here by a translational movement, - however, it is possible with another suitable drive unit, which consist of a shape memory material or can be made of bimetal, the position change of the actuating element along the Verstellweges cause by a rotational movement.
- the return spring 16 after a cooling of the drive unit 15, returns the actuating element 13 back into the first positioning position according to FIG. 2.
- a through-flow opening 21 is formed, which is open in FIG. 2 and which represents a bypass to the opening cross-section 10.
- this flow opening 21 is closed by the control element 13 located in the second setting position.
- This passage opening 21 explains the different volume flow dependencies 11, 12 according to FIG. 4.
- the increased flow rate of the volume flow dependence 12 results from the fact that additional water flows through the open flow opening 21.
- the actuating element 13 can be moved into the closed throughflow opening 21 beyond the second setting position shown in FIG. 1 during a further thermal expansion of the temperature-sensitive medium 18.
- the adjustment path of the adjusting element 13 is thus set up stop-free at least at its second positioning position (FIG. 1) closer to the end, and the adjusting element 13 is beyond the second setting position into a setting end position adjustable as the medium 18 continues to expand.
- the actuating element 13 has a contact surface 22.
- the contact surface 22 is cylindrical and extends as an outer cylinder about the axis of the third
- This contact surface 22 interacts with a stationary counter-contact surface 23.
- the countercontact surface 23 is designed as an inner cylinder, wherein the diameter of the countercontact surface 23 is matched to the outer diameter of the contact surface 22 in such a way that a dense or almost dense closure of the throughflow opening 21 results in the second setting position.
- This tight seal may in one embodiment be made by an additional O-ring (not shown). However, this increases the friction of the actuator and the manufacturing cost.
- the adjustment path of the adjusting element 13 is rectilinear.
- the adjustment is aligned in the flow direction.
- curved or curved adjustment paths are set up, for example, in which the adjusting element 13 is pivoted or rotated.
- the displacement can also be aligned transversely, in particular perpendicular, to the flow direction.
- the contact surface 22 is oriented longitudinally or tangentially to the displacement path of the adjusting element 13 in order to allow the contact surface 22 to move past the mating contact surface 23.
