Abstract
A low cost water filter apparatus including a valve rotor rotatable within a valve housing which rotor may be rotated within the valve housing when necessary for the purpose of engaging a bypass safety feature, or for the purpose of shutting off the flow of water through the filter unit prior to changing the filter element.
Claims4
A water filtering apparatus comprising:
- a valve rotor, having an inlet bore and an outlet bore, said inlet and outlet bores communicating respectively with oppositely disposed entering and exiting openings in said rotor;
- a housing for said rotor, said housing having therein housing entering and housing exiting openings corresponding to those of said rotor and communicating therewith when said rotor is in filtering position, positioned such that if said valve rotor be rotated, said rotor entering opening and said rotor exiting opening may be discommunicated thereby from said housing entering opening and said housing exiting opening respectively;
- a filter tank detachably, sealably mounted to said housing;
- a hollow, elongated filter element having permeable walls defining a central cavity, said filter element mounted in said filter tank with one end thereof opening into one said bore of said rotor;
- and
- automatic vacuum relief means for releasing the vacuum created within said filter tank when said entering and exiting openings of said rotor have been discommunicated from said entering and exiting openings of said housing, whereby said apparatus may be more easily disassembled;
- said automatic vacuum relief means comprising a vacuum opening in said filter tank communicating said filter tank with the ambient atmosphere;
- and a vacuum seal covering said vacuum opening when said valve rotor is in filtering position discommunicatable therefrom when said valve rotor is rotatably positioned in bypass configuration.

A water filtering apparatus comprising:
- a valve rotor, having a radially disposed inlet bore and an axially disposed outlet bore, said inlet and outlet bores communicating respectively with oppositely disposed rotor entering and rotor exiting openings;
- a housing for said rotor, said housing having therein housing entering and housing exiting openings corresponding to said rotor entering and rotor exiting openings and communicating therewith when said rotor is in filtering position, positioned such that if said valve rotor be rotated said rotor entering opening and said rotor exiting opening may be discommunicated thereby from said housing entering opening and said housing exiting opening respectively;
- a filter tank detachably, sealably mounted to said housing;
- and
- a hollow elongated filter element having permeable walls defining a central cavity, said filter element mounted in said filter tank with one end thereof opening directly into and communicating directly with said axially disposed outlet bore of said rotor, whereby filtered water in said central cavity may unimpedably flow therefrom through said outlet bore of said rotor.
