Abstract

A rotary vessel for a filter assembly is rotatably mountable in a housing of the filter assembly and has a body having an open end, a cover receivable on the body to close the open end, and a releasable locking device that is manually operable to selectively lock and unlock the cover relative to the body.

First claim

What is claimed is:

1. A rotary vessel for a filter assembly, the rotary vessel configured to be rotatably mounted in a housing of the filter assembly, the rotary vessel comprising:
a vessel body having an open end;
a cover receivable on the vessel body to close the open end; and
wherein the vessel body comprises
a bearing tube extending axially through an interior of the vessel body and defining a central bore configured to receive a spindle of the filter assembly such that the rotary vessel with the vessel body and the cover are rotatable about a longitudinal axis of the spindle;
at least one recess arranged on the bearing tube;

wherein the cover further comprises:
an aperture, wherein the spindle protrudes through the aperture of the cover when the cover is received on the vessel body;

a releasable locking device selectively locking and unlocking the cover to the bearing tube, comprising:
at least one radially moveable projection on the cover including one or more radially moveable lugs arranged in the aperture of the cover;

wherein the at least one recess is configured to receive the one or more radially moveable lugs;
wherein the one or more radially moveable lugs, when received in the at least one recess, limits or inhibits a relative rotation of at least a part of the cover relative to the vessel body.

2. The rotary vessel according to claim 1 , wherein
the releasable locking device comprises:
a bayonet fitting arranged between the aperture and the bearing tube.

3. The rotary vessel of claim 1 , wherein
the releasable locking device is moveable relative to the cover; relative to the vessel body; or relative to the cover and to the vessel body.

4. The rotary vessel of claim 2 , wherein
the aperture is a non-circular keyway; and
the bayonet fitting comprises
radial protrusions arranged at the bearing tube,
wherein the radial protrusions are configured to pass through the keyway in a first rotational position of the aperture relative to the bearing tube, and
wherein, subsequent to the radial protrusions having passed through the keyway, a rotation of the cover relative to the bearing tube into a second rotational position of the aperture relative to the bearing tube moves the radial protrusions into an engagement at the cover preventing a removal of the cover from the bearing tube.

5. The rotary vessel of claim 1 , wherein
the cover comprises
a first part and
a second part,
wherein the first part comprises
the aperture and

the second part comprises
a through-hole configured to receive the bearing tube,

wherein the first part is rotatable relative to the second part.

6. The rotary vessel of claim 1 , wherein
the rotary vessel comprises
a drive member comprising
nozzles supplied with a liquid to be filtered from an axial bore of a spindle of the filter assembly,
wherein the drive member is configured to rotate the rotary vessel by a reaction to a liquid emission from the nozzles.

7. The rotary vessel of claim 1 , wherein
the one or more radially moveable lugs each comprises a ball plunger.

8. A filter assembly comprising
a housing and further comprising
a rotary vessel of claim 1 ,

wherein the rotary vessel is rotatably mounted in the housing.
