APPARATUS FOR FILTERING AND/OR CONDITIONING AND/OR PURIFYING A FLUID SUCH AS WATER

摘要

An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve permitting water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. The outlet port may be directly connected to an appliance that uses water, eliminating possible contamination that may occur when water is brought indirectly form the outlet port to the appliance. A flapper valve is provided in the canister preventing back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface. The flapper valve also is provided with an actuating means to automatically open the flapper valve when the canister is mounted on the interface.
