In order to avoid repetition, only the differences of the alternative flow quantity regulator 201 with respect to the flow rate regulator 1 from FIG. Otherwise, reference is made to the descriptions of Figures 1 and 2 ver.
- yet another exemplary embodiment of the flow rate regulator 301 is shown, wherein the flow rate regulator 301 essentially has the same structure as the flow volume regulator 1 shown in FIG.
- the flow rate regulator 301 is characterized in particular by another Betigungs worn 315, which comprises a servo motor 360 which is at least electrically operated in this embodiment according to the figure 4.
- the positioning motor 360 is driven so that the positioning motor 360 is operated in response to a movement of the service water control piston 30.
- the actuating device 315 comprises a detection unit 361 for detecting a movement of the service water control piston 30.
- the detection unit 361 and the positioning motor 360 are electrically connected to each other by means of a data bus system 362, so that a detected movement of the service water control piston 30 to detection sensors 363 of the detection unit 361 initiates an action on the positioning motor 360, whereby the heating water control piston 31 moves accordingly can be.
- Actuator 315 further includes an electrical control and / or Control device 364 for controlling or regulating an actuation of the Schumacherstellven til raised 4, in particular in response to an actuation of the service water control valve device. 2
- characteristic curves can optionally be set on the actuating device 315.
- the Actuate supply device 315 in this embodiment also has a Kalibrierein direction 365 for calibrating a position of Banklessstellventil raised 4, in particular the Schumacher Kunststoffkolbens 31 and / or the electrically operated Stellmo sector 360, depending on a position of the service water control valve device. 2
- FIG. 5 Another alternative flow rate regulator 401 is shown in FIG. 5.
- This further alternative flow rate regulator 401 also essentially has a service water control valve device 2 with a first housing part 3 and a heating water control valve device 4 with a second housing part 5. Since the custom wasserstellventil styles 2 and the Schumacherstellventil responded 4 have already been explained before standing, will be omitted here again to a detailed detailed description Be.
- the two housing parts 3 and 5 are spatially separated from each other, so that they are not physically in operative contact with each other. In this respect, this is already a heat transfer from the Edelwasserstellventil worn 4, so the hot side of the white alternative flow controller 1 to the service water control valve device 2, so the cold side of the other alternative flow rate controller 1, not or hardly possible.
- the further alternative flow rate regulator 401 has a distance-extending actuator 415 with a stretch-extending force Transmission element 470 in order to significantly reduce a possible heat transfer with respect to the actuating device 415 between the Schumacherstellventil planted 4 and the DHW valve device 2.
- the lengthening actuating device 415 or the lengthening force transmission element 470 have a shape deviating from a straight line, so that a distance 471, along a component-related heat transfer between Schumacherstellventil planted 4 and the service water control valve device 2 can take place significantly extended, thereby increasing the risk of undesirable or critical heat transfer at the actuator 415 can be significantly reduced.
- the distance-extending actuating device 415 again has a cable mechanism (not numbered separately), but this time in the form of a Bowden cable unit 472.
- the Bowden cable unit 472 extends from an outer side 473 of the service water control valve device 2 to an outer side facing away from the outer side 474 of the heating water control valve device 4.
- the two outer sides 473 and 474 are arranged facing away from each other, in contrast to the facing end 9 and 10 (inner sides) of the two Stellventilein directions 3 and 4.
- the Bowden cable unit 472 comprises a cable element 475 which extends from the water control piston 30 to the heating water control piston 31 or is mechanically operatively connected thereto, and a jacket element 476, from which the cable element 475 is supported laterally.
- the cable element 475 and the jacket member 476 hereby denote the actual bow denzug 477 of the Bowden cable unit 472, wherein the cable member 475 is supported by the man telelement 476 especially laterally very well, so that not only tensile forces, but also compressive forces or shear forces with the cable element 475 be transferred can.
- control pistons 30 and 31 of the further alternative flow quantity regulator 401 can interact with one another in a heat-insulating manner, whereby the risk of undesirable heat transfer is further reduced.
- the extension-lengthening actuating device 415 has at least four cam sections 478 (numbered only by way of example) into which the track-extending force-transmitting element 470 is bent.
- the track-extending force transmission element 470 has a shape deviating from a straight line and / or a longitudinal axis 26.
