Abstract

A liner for a filter sub-assembly has a wall having an innermost surface that bounds a cavity extending between opposing first and second ends of the liner. The wall has a deflected portion extending into the cavity and delimiting an opening. The liner may be used in a rotor of a filter assembly.

First claim

What is claimed is:

1 . A liner for a filter sub-assembly, the liner comprising:
a wall comprising an innermost surface configured to bound a cavity extending between a first end of the liner and an opposing second end of the liner, the wall further comprising a deflected portion configured to extend into the cavity and to delimit an opening.

2 . The liner according to claim 1 , wherein the deflected portion provides a partially closed end of the liner.

3 . The liner according to claim 1 , wherein the wall is formed as a monolithic tubular sleeve.

4 . The liner according to claim 1 , wherein the wall is formed of or comprises a resiliently deformable material.

5 . The liner according to claim 1 , wherein the wall is formed of or comprises silicone.

6 . The liner according to claim 1 , wherein the wall is formed of or comprises a fiber reinforced polymer.

7 . The liner according to claim 6 , wherein the fiber reinforced polymer includes a first plurality of fibers oriented to extend circumferentially along the wall.

8 . The liner according to claim 7 , wherein the fiber reinforced polymer includes a second plurality of fibers oriented to extend at least partially between the first and second ends of the liner.

9 . The liner according to claim 6 , wherein the fiber reinforced polymer includes a plurality of fibers oriented to extend at least partially between the first and second ends of the liner.

10 . The liner according to claim 1 , wherein at least the deflected portion of the wall is substantially rigid.

11 . The liner according to claim 1 , further comprising one or more stiffening members connected to the deflected portion and extending substantially perpendicularly away from the deflected portion.

12 . The liner according to claim 1 , wherein the deflected portion of the wall forms an acute angle with a remainder of the wall.

13 . The liner according to claim 1 , further comprising a first substantially rigid collar proximate the first end of the liner.

14 . The liner according to claim 13 , wherein the first substantially rigid collar is encapsulated within the wall.

15 . The liner according to claim 13 , further comprising a second substantially rigid collar proximate the second end of the liner.

16 . The liner according to claim 15 , wherein the second substantially rigid collar is encapsulated within the wall.

17 . The liner according to claim 16 , wherein the second substantially rigid collar is encapsulated within the deflected portion of the wall.

18 . The liner according to claim 1 , wherein the wall comprises a foldable region configured to fold so as to collapse the liner such that a first portion of the liner is receivable within a second portion of the liner.

19 . The liner according to claim 18 , wherein the foldable region has a stiffness that is less than a stiffness of a remainder of the wall.

20 . The liner according to claim 1 , wherein the liner is tapered such that a width of the liner reduces between the first and second ends of the liner.

21 . A filter sub-assembly comprising:
a rotary vessel comprising a rotor body and a closure member separably attachable to the rotor body; and a liner comprising a wall comprising an innermost surface configured to bound a cavity extending between a first end of the liner and an opposing second end of the liner, the wall further comprising a deflected portion configured to extend into the cavity and to delimit an opening; wherein the liner is receivable within the rotor body to line an inner surface of the rotor body; wherein the rotor body comprises a first chamber and a second chamber; wherein the deflected portion of the liner in part delimits the first and second chambers of the rotor body and the opening fluidly connects the first and second chambers to one another.

22 . The filter assembly according to claim 21 , wherein the closure member is separably attachable to the rotor body by insertion of the closure member into an open end of the rotor body.

23 . The filter assembly according to claim 21 , wherein the closure member is sealable against the rotor body by the liner.

24 . The filter assembly according to claim 21 , wherein the liner is removable from the rotor body by separation of the closure member from the rotor body.

25 . The filter assembly according to claims 21 , wherein the liner comprises a retention member to facilitate separable attachment of the liner to the closure member.
