Depending on the setting angle of the setting drum 10', the quantity of fluid flowing from the interior of the setting drum 10' to the first outlet A1 can vary by aligning either the wider or the narrower portions of the first slot 15 with the first exit A1, depending on the adjustment angle.
  • the setting drum 10 ' In the setting position shown in representation A, the setting drum 10 'is in a first open position, in which the widest area of the first slot 15 is aligned with the first outlet A1, so that the maximum possible amount of fluid from the interior of the setting drum 10' through the first slot 15 can flow to the first outlet A1.
  • the flow cross section to outlet A1 is 100%.
  • a flow cross-section of 100% would be provided by inlet A1.
  • the setting drum 10' is in a second open position.
  • the fluid flowing or flowing into the interior of the adjusting drum 10' can no longer flow to or from the first outlet A1, but rather to or from the second outlet A2.
  • the setting drum 10' is oriented in such a way that the widest area of the second slot 15 is aligned with the second outlet A2, so that the maximum possible amount of fluid can flow through the second slot 15 to the second outlet A2.
  • the flow cross section to outlet A2 is also 100% here.
  • a flow cross-section of 100% would be provided by inlet A2.
  • the setting drum 10' is in a third open position. In this open position, both slots 15 are aligned to the same extent with the associated outlet A1, A2. In this respect, the fluid flowing into the interior of the adjusting drum 10' can flow through the first of the slots 15 the first output A1, as well as through the second of the slots 15 to the second output A2, ie simultaneously to both outputs A1, A2.
  • the setting drum 10′ is oriented in such a way that neither the widest nor the narrowest area of the two slots 15 is aligned with the respective outlet A1, A2, but rather the medium-width area.
  • the flow cross section is 50%, ie half of the amount of fluid flowing into the interior of the setting drum 10' flows through one of the slots 15 to one of the outlets A1, A2.
  • half the fluid would flow through port A1 and the other half of the fluid would flow through port A2.
  • the through-flow cross section for both outlets A1, A2 can be set essentially steplessly and linearly from 0% to 100%.
  • the five exemplary embodiments of the fluid control device 1 described above advantageously provide a fluid control device 1 that is easy to assemble and inexpensive to produce and has a wide range of functional options, since essentially any type of actuator 2 and control means 10 can be used to form a wide variety of types of fluid control devices or can be combined for a wide range of applications.
