Abstract
There is provided a filter sub-assembly that comprises a rotary vessel having a rotor body and a closure member to close an opening of the rotor body. The sub-assembly further comprises a liner that is receivable within the rotor body to line an inner surface thereof. The liner is also fluidly sealable to the closure member by a centrifugal force directed radially outwardly from an axis of rotation, about which the rotary vessel is rotatable. The sub-assembly has particular application in a centrifugal filter of a motor vehicle, for example for cleaning engine oil in an engine lubrication system.
Claims18
A filter sub-assembly comprising:
- a rotary vessel having
- a rotor body and
- a closure member to close an opening of the rotor body;
- and
- a liner receivable within the rotor body to line an inner surface thereof and fluidly sealable to the closure member by a centrifugal force directed radially outwardly from an axis of rotation about which the rotary vessel is rotatable,
- wherein the liner comprises:
- a radially outwardly facing sealing surface, relative to the axis of rotation, which is fluidly sealable against the closure member by the centrifugal force;
- and
- a wall extending between opposing first and second ends of the liner, the wall having an edge region proximate the first end that provides the radially outwardly facing sealing surface.
