Abstract
An apparatus for a switchable filter assembly includes a first conduit coupled to a second and a third conduit, where a liquid has the ability to flow through the first conduit to the second conduit and the third conduit, and where the second conduit and the third conduit are arranged in parallel. A first assembly is capable of sliding inside the first conduit, such that a position of the first assembly determines an amount of liquid flowing to the third conduit. The first assembly includes a compressible member coupled to a first structure, where the first structure prevents the liquid from passing through the first conduit to the third conduit. An amount of compression of the compressible member coupled to the first structure is dependent on a pressure of the liquid flowing from the first conduit to the second conduit.
