Abstract:
1. A continuous fluid filtration system comprising: a filter support including an inlet passage to receive fluid entering said system and an outlet passage to deliver filtered fluid out of said system; a first filter housing assembly and a second filter housing assembly connected to said filter support, each filter housing assembly including a chamber disposed therein, filter media disposed within said chamber, an input port to deliver fluid into said chamber, an output port to deliver filtered fluid out of said chamber, and a housing head located at one end of each filter housing assembly, wherein said input and output ports of each filter housing assembly are disposed on said housing head of each filter housing assembly; and a single valve configured to selectively alternate fluid flow between said first and second filter housing assemblies by establishing fluid communication between said inlet passage and one of said input ports of said first and second filter housing assemblies and between said outlet passage and a corresponding one of said output ports of said first and second filter housing assemblies, wherein said valve includes an engaging surface that engages an outer planar surface of said filter support, said valve is configured to be slidably displaced in two opposite linear directions and along said outer planar surface to selectively alternate fluid flow between said first and second filter housing assemblies, and each slidable displacement of said valve results in movement of said valve spatially closer toward one of said first and second filter housing assemblies and further away from the other of said first and second filter housing assemblies.
