SEALING APPARATUS FOR A WATER FILTER CANISTER
An apparatus includes a fluid filter canister that includes an internal seal disposed within an inlet recess to provide a seal between a flow of unfiltered fluid into the filter canister and the ambient environment.
1 . A filter canister apparatus for engagement with a manifold, said apparatus comprising:
an inlet annular recess defined by at least a first mating surface, and wherein the first mating surface is configured to retain a seal thereon;
a seal retained on the first mating surface; and
an outlet annular recess defined by at least a second mating surface, wherein the second mating surface is substantially continuous and free of sealing means.
2 . The apparatus of claim 1 , wherein the seal comprises an o-ring.
3 . The apparatus of claim 1 , wherein the seal comprises an elastomeric seal.
4 . The apparatus of claim 1 , wherein the seal comprises an interference mechanism.
5 . The apparatus of claim 1 , wherein the seal forms a seal against an inlet boss of the manifold upon engaging the filter canister to the manifold.
6 . The apparatus of claim 5 , wherein the seal presses against the bottom surface of an inlet boss operably coupled to the flow inlet channel to block fluid flow from moving to the ambient environment.
7 . The apparatus of claim 1 , wherein the seal forms a seal against an inlet boss of the manifold via water pressure within the filter canister that pushes the seal against the inlet boss.
8 . A filter canister apparatus comprising:
an inlet annular recess defined by at least a first mating surface, the first mating surface comprising an annular outer wall, and wherein the first mating surface comprises an annular slot for retention of a seal;
a seal retained on the first mating surface; and
an outlet annular recess defined by at least a second mating surface, wherein the second mating surface is substantially continuous and free of sealing means.
9 . The apparatus of claim 8 , wherein the seal comprises an o-ring.
10 . A fluid filtration system comprising:
a manifold having a manifold inlet port and a manifold outlet port, a check valve disposed for fluidly sealing at least one of said ports, a flow inlet channel leading to the check valve, the manifold inlet port operably fluidly coupled to a fluid source for receiving a flow of fluid and to a flow inlet channel, the manifold outlet port fluidly coupled to a flow outlet channel;
the flow inlet channel having an intake opening for directing fluid conveyed therein, the intake opening defined in a margin of a depending inlet boss of the manifold;
an outlet boss depending from the inlet boss and having a circumferential outer margin, the outlet boss also having an outlet opening for directing fluid conveyed therein, the outlet opening fluidly coupled to the flow outlet channel, the flow outlet channel fluidly coupling the outlet opening to the manifold outlet port; and
a filter canister having:
an inlet annular recess defined by at least a first mating surface, and wherein the first mating surface is configured for retention of a seal;
a seal retained on the first mating surface; and
an outlet annular recess defined by at least a second mating surface, wherein the second mating surface is substantially continuous and free of sealing means.
11 . The system of claim 10 , wherein the seal comprises an interference mechanism.
12 . The system of claim 10 , wherein the seal comprises an o-ring.
13 . A filter canister apparatus comprising:
at least on annular canister interlocking member comprising an inlet annular recess defined at least in part by an annular wall comprising an inner surface, the inner surface providing a first mating surface;
an outlet annular recess with at least one outlet port defined in a bottom margin of the outlet annular recess; and
an internal seal disposed within the interlocking member proximate the first mating surface to provide a seal between a flow of unfiltered fluid into the filter canister and the ambient environment.
14 . The apparatus of claim 13 , wherein the internal seal comprises an o-ring.
15 . The apparatus of claim 13 , further comprising:
an annular insert component coincident with the at least one annular canister interlocking member; said insert component comprising an inner rim, an outer rim and an annular surface extending therebetween; and
wherein the upper edge of the outer rim of the annular insert component defines a lower side of an o-ring groove within the at least one annular canister interlocking member and wherein the o-ring is disposed in the groove.
16 . The apparatus of claim 15 , wherein the outer side and upper sides of the o-ring groove are defined by the inner wall of the at least one annular canister interlocking member.
17 . A fluid filtration system comprising:
a manifold having a manifold inlet port and a manifold outlet port, a check valve disposed for fluidly sealing at least one of said ports, a flow inlet channel leading to the check valve, the manifold inlet port operably fluidly coupled to a fluid source for receiving a flow of fluid and to a flow inlet channel, the manifold outlet port fluidly coupled to a flow outlet channel;
the flow inlet channel having an intake opening for directing fluid conveyed therein, the intake opening defined in a margin of a depending inlet boss of the manifold;
an outlet boss depending from the inlet boss and having a circumferential outer margin, the outlet boss also having an outlet opening for directing fluid conveyed therein, the outlet opening fluidly coupled to the flow outlet channel, the flow outlet channel fluidly coupling the outlet opening to the manifold outlet port; and
a filter canister having:
an inlet annular recess defined by at least a first mating surface, the first mating surface comprising an annular wall;
an outlet annular recess with at least one outlet port defined in a bottom margin of the outlet annular recess; and
an internal seal disposed on the first mating surface to provide a seal between a flow of unfiltered fluid into the filter canister and the ambient environment.
18 . The system of claim 17 , wherein the internal seal comprises an o-ring.
19 . The system of claim 17 , further comprising:
an annular insert component coincident with the at least one annular canister interlocking member; said insert component comprising an inner rim, an outer rim and an annular surface extending therebetween,
wherein the upper edge of the outer rim of the annular insert component defines a lower side of an o-ring groove within the at least one annular canister interlocking member and wherein the o-ring is disposed in the groove.
20 . The system of claim 19 , wherein the outer side and upper sides of the o-ring groove are defined by the inner wall of the at least one annular canister interlocking member.
