  • Patent number: 8097157
    Abstract: A fluid filtration system is disclosed comprising a manifold assembly comprising a mounting bracket, an alignment collar connected to the mounting bracket, and a latch assembly moveable with respect to the mounting bracket and alignment collar. The system further comprises a filter cartridge comprising a filter cartridge outer surface and a cartridge latching structure formed on the filter cartridge outer surface to interact with the latch assembly. When the filter cartridge is aligned with the alignment collar and inserted into the manifold assembly, the filter cartridge is (i) latched into the manifold assembly by translating the filter cartridge into the manifold assembly to cause movement of the latch assembly to engage the cartridge latching structure; and (ii) unlatched from the manifold assembly by translating the filter cartridge into the manifold assembly to cause movement of the rotating latch assembly to disengage the cartridge latching structure.

  • Publication number: 20100270327
    Abstract: A liquid storage tank assembly includes a baffle member and a tank assembly. The baffle member includes a generally helical or spiral shaped portion. The baffle member defines a spiral flow path between inlet and outlet openings of the tank assembly. When the baffle member is positioned within the tank and the tank assembly holds a volume of a first liquid, input of a supply of a second liquid at the inlet to the tank assembly forces the first liquid along the spiral flow path and out of the tank assembly exit without substantial mixing of the first and second liquids before substantially all of the first liquid has been dispensed.

  • Publication number: 20100264078
    Abstract: A filter unit that includes a slide assembly and a head assembly. The slide assembly is moveably mounted to the head assembly. The head assembly is configured to receive an end portion of a filter cartridge in releasable engagement. The slide assembly is movable between a first position in which the slide assembly prevents disengagement of the filter cartridge from the head assembly, and a second position in which the filter cartridge is permitted to disengage from the head assembly. In the second position, the slide assembly maintains engagement with the head assembly until an external force is applied by engagement of the filter cartridge with the slide assembly when removing the filter cartridge from the head assembly.

  • Publication number: 20080237924
    Abstract: A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be, but is not necessarily, larger in cross dimension than the port. In one embodiment, the filtration element is a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element.

  • Publication number: 20070221561
    Abstract: Provided are liquid filtration systems and filter elements. An aspect of the invention provides a filter element comprising: a filter block having an inlet and an outlet; an end cap having a handle and a passage, the passage operatively connecting the outlet of the filter block with an end location; and a housing comprising a shroud and an opening, the housing being adjacent to the end cap, wherein the inlet of the filter block is directly operatively connected to the opening of the housing. Another aspect of the invention provides a filtration system comprising the filter element and a pressure vessel. The pressure vessel comprises an inlet port that is adjacent to the shroud such that upon fluid flowing through the inlet port, the fluid contacts the shroud and the direction of flow changes, and wherein the inlet port is in fluid communication with the inlet of the filter block.
