  • Patent number: 6776906
    Abstract: A bracket system holds one or more filters in quick-attach and quick-release fashion. Bracket modules are combined in modular fashion, with tubing or other conduit between the modules, to create a “bank” of filters easily changed in number, arrangement, and flow scheme. Preferably, the bracket system comprises pairs of top modules and bottom modules that capture and support the top end and bottom end of a filter. Filter inlet and outlet ports preferably slide onto and off of cooperating tubes or ports in the bracket modules, for installation and removal of the filters onto/from the modules without tools or threaded connections. A top retaining member preferably pivots off of its respective filter, so that the filter may be lifted up off of its respective bottom module. The bottom modules may be pivotal, so that lifting the filter up from the bracket system is facilitated by allowing the filter top end to also pivot out away from the top module.

    Abstract: Disclosed is a manifold for a replaceable fluid filter cartridge. The manifold possesses inlet and outlet passages and a housing. A first valve assembly is provided in the inlet passage. The housing is provided with first and second fitting mechanisms which have second and third valve assemblies. Fitting portions of the first and second fitting mechanisms are fitted into outer and inner flanges of the filter cartridge. Upon coupling the filter cartridge to the manifold, a valve stem of the second valve assembly is positioned on an upper end surface of the inner flange, and thereby a flow channel is defined. Thus, fluid flows through the inlet passage into the filter cartridge. Upon decoupling the filter cartridge from the manifold, the valve stem of the second valve assembly is separated from the upper end surface of the inner flange to shut off fluid flow from the inlet passage into the filter cartridge.
