  • Patent number: 10773191
    Abstract: A filter manifold includes a housing and a shuttle. The shuttle is disposed within the housing such that the shuttle is movable relative to the housing between a plug position and a flow position along an axial direction. The shuttle is also coupled to the housing such that the shuttle is non-rotatable relative to the housing about the axial direction. A spring is disposed within the housing. The spring is connected to the shuttle such that the tension spring urges the shuttle towards the plug position. The shuttle is positioned at the flow position of the shuttle when a filter cartridge is coupled to the filter manifold.

  • Patent number: 10758080
    Abstract: A refrigerator appliance and extraction is provided herein. The extraction fluid assembly may include a fluid tank, an open container, a filter assembly, a dispenser housing, and a precision doser. The fluid tank may define an extraction chamber to receive a liquid solvent. The open container may be selectively disposed on the fluid tank to hold an additive within the extraction chamber. The filter assembly may be positioned beneath the fluid tank along a vertical direction in fluid communication with the extraction chamber. The dispenser housing may support the filter assembly. The dispenser housing may also define a dispensing chamber positioned beneath the filter assembly in fluid communication therewith. The precision doser may be in fluid communication with the dispensing chamber to direct an extraction fluid therefrom.
