Abstract
The invention relates to a device for metering an additive into a fluid, containing a valve body, a fluid inlet, and a fluid outlet. A first channel system extends between the fluid inlet and the fluid outlet in the valve body, and a second channel system extends between the fluid inlet and the fluid outlet in the valve body such that in the operating state fluid can flow from the fluid inlet to the fluid outlet either through the first channel system or through the second channel system. The valve body contains a docking element which is configured for docking a cartridge for the additive. A switchover device is provided which can be switched if the cartridge is docked such that the second channel system is fluidically connected to the cartridge when the cartridge is connected to the docking element.
Claims14
A device for metering an additive into a fluid containing a valve body, a fluid inlet and a fluid outlet, wherein a first channel system in the valve body extends between the fluid inlet and the fluid outlet in the valve body and a second channel system extends between the fluid inlet and the fluid outlet, such that in an operating state a fluid can flow either through the first channel system from the fluid inlet to the fluid outlet or through the second channel system from the fluid inlet to the fluid outlet, wherein the valve body contains a docking element which is configured for docking a cartridge for an additive, wherein a switchover device is provided which is configured to be switched if the cartridge is docked such that the second channel system is fluidically connected to the cartridge when the cartridge is connected to the docking element, wherein the docking element includes an internal thread configured to engage an external thread on a cartridge neck.
A method for metering an additive into a fluid, comprising a device containing a valve body, a fluid inlet and a fluid outlet, wherein a first channel system in the valve body extends between the fluid inlet and the fluid outlet and a second channel system extends between the fluid inlet and the fluid outlet, such that a fluid can flow in an operating state either through the first channel system from the fluid inlet to the fluid outlet or through the second channel system from the fluid inlet to the fluid outlet, wherein no additive is added to the fluid when the fluid is passed through the first channel system, wherein the additive is added to the fluid when the fluid is passed through the second channel system, wherein a docking element includes an internal thread configured to engage an external thread on a cartridge neck.
