Abstract
An improved cartridge housing assembly and distributor is provided for a water filtration system installed at a point-of-use or a point-of entry of plumbing networks in buildings. The improvements include a mechanism for actuating a shut-off valve and a pressure-relief valve upon removing the housing assembly from the distributor, a bayonet-type mount between the housing assembly and the distributor, a housing lid to prevent spilling of water when the housing assembly is removed from the distributor, and fastener clips that allow for modular attachment of the distributor to plumbing fittings and a mounting bracket.
Claims10
An apparatus for filtering water, the apparatus comprising:
- (a) a housing assembly comprising a housing canister defining a housing interior for holding a filtration medium;
- (b) a distributor assembly defining at least part of an inflow passage for directing water flow from a distributor inlet to the housing interior, and at least part of an outflow passage for directing water flow from the housing interior to a distributor outlet;
- and
- (c) a shut-off valve for regulating water flow between the housing interior and the distributor inlet, and the distributor outlet;
- and
- (d) wherein the housing assembly is removably attachable to the distributor by rotation relative to the distributor in a first direction, whereupon the housing assembly actuates movement of the shut-off valve to an open position permitting water flow through the inflow passage, and through the outflow passage;
- and
- (e) wherein the housing assembly is detachable from the distributor by rotation relative to the distributor in a second direction opposite to the first direction, whereupon the housing assembly actuates movement of the shut-off valve to a closed position preventing water flow through the inflow passage, and through the outflow passage.
An apparatus for filtering water, the apparatus comprising:
- (a) a housing assembly comprising:
- (i) a housing canister defining a housing interior for holding a filtration medium;
- and
- (ii) a housing lid removably attached, in sealing relationship, to the housing canister, wherein the housing lid defines a housing lid aperture permitting water flow into and out of the housing interior;
- and
- (b) a distributor removably attachable to the housing assembly, and defining at least part of an inflow passage for directing water flow from a distributor inlet to the housing interior via the housing lid aperture, and at least part of an outflow passage for directing water flow from the housing interior to a distributor outlet via the housing lid aperture.
A distributor assembly for use in a water filtering apparatus comprising a housing for holding a filtration medium, the assembly comprising:
- (a) a distributor for directing water flow into and out of the housing, the distributor defining:
- (i) a distributor inlet for removably receiving an inlet fitting in sealing relationship to the distributor;
- and
- (ii) a distributor outlet for removably receiving an outlet fitting in sealing relationship to the distributor;
- and
- (b) at plurality of identical fasteners, wherein each fastener comprises a pair of clip members resiliently separable from each other, wherein the plurality of fasteners comprises:
- (i) a first fastener, the clip members of which are removably insertable through a first pair of passages defined by the distributor to engage the inlet fitting received in the distributor inlet, and thereby removably secure the inlet fitting within the distributor inlet;
- and
- (ii) a second fastener, the clip members of which are removably insertable through a second pair of passages defined by the distributor to engage the outlet fitting received in the distributor outlet, and thereby removably secure the outlet fitting within the distributor outlet.
