Rotary vessel for a filter assembly

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 rotary vessel body to close the open end;
• 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;
• wherein the cover further comprises
• an aperture, wherein the spindle protrudes through the aperture when the cover is received on the vessel body;
• a releasable locking device configured to be manually operable to selectively lock and unlock the cover to the bearing tube of the vessel body;
• wherein the aperture is a non-circular keyway and a bayonet fitting comprises radial protrusions arranged at the bearing tube of the rotary vessel body,
• 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.
