Definitions

  • the present invention relates to a filter element and a cover assembly for such a filter element.
  • Filters are used in a variety of applications to remove particulates and other contaminants from a fluid stream.
  • Filter assemblies conventionally comprise a filter element which includes a filter media which is attached to a tap plate.
  • a housing having a head part and a body part, including the tap plate, is then place around the filter element.
  • the tap plate also includes a seal or gasket.
  • the filter head part has a spigot extending from the head.
  • the spigot typically has an external thread.
  • the tap plate of the filter element includes an internally threaded bore which can put into threaded engagement with the spigot on the housing head part.
  • the tap plate can then be rotated and, in doing so, the filter element can translate along the longitudinal axis of the spigot towards or away from the filter head, depending upon the direction of rotation.
  • the filter element and body part are mounted on the spigot and rotated so that the filter element translates towards the filter head until the seal engages the filter head and seals the filter element assembly.
  • one of the problems that can occur is that, under situations of high pressure load, the tap plate can become bowed or deformed out of its plane, such that the seal compression with the filter head plate can be reduced. This is particularly acute where the seal is provided towards the outer edge of the tap plate.
  • moving the seal inwards towards the centre of the tap plate makes the filter assembly more susceptible to vibration which can lead to failure of the tap plate over time.
  • a filter element comprising a cover plate having an aperture, a filter media connected to the cover plate, and an adaptor detachably coupled to the cover plate and located within the aperture, the adaptor having a threaded internal cylindrical surface for engagement with an attachment portion of a filter head to attach the filter element to the filter head, the filter element further comprising a coupling arrangement for detachably coupling the adaptor to the cover plate, the adaptor being configured to engage with the cover plate by means of the coupling arrangement such that there is no relative movement between the cover plate and the adaptor when the cover plate and adaptor are engaged, and such that the adaptor and cover plate work as a unitary body for engagement with the attachment portion of the filter head.
  • the filter element can be connected to a filter head by means of the internal threaded surface of the adapter engaging with a threaded spigot of the filter head. Because the adaptor and cover plate are coupled together by means of the coupling arrangement so that there is no relative movement between the cover plate and the adaptor, the cover plate and adaptor work as a single unit. Thus, the cover plate can be rotated, and at the same time the adapter consequently rotates around the spigot as the threads engage, which causes the filter element to translate along the longitudinal axis of the spigot bringing the cover plate towards the filter head.
  • a cover assembly for a filter element comprising a cover plate having an aperture, and an adaptor detachably coupled to the cover plate and located within the aperture, the adaptor having a threaded internal cylindrical surface for engagement with an attachment portion of a filter head to attach the filter element to the filter head, the cover assembly further comprising a coupling arrangement for detachably coupling the adaptor to the cover plate, the adaptor being configured to engage with the cover plate by means of the coupling arrangement such that there is substantially no relative movement between the cover plate and the adaptor when the cover plate and adaptor are engaged, and such that the adaptor and cover plate work as a unitary body for engagement with the attachment portion of the filter head.
  • an adaptor for a filter element cover assembly comprising a body having a threaded internal cylindrical surface for engagement with an attachment portion of a filter head to attach the filter element to the filter head and an external surface, the adaptor having a plurality of spaced projections provided circumferentially around the external surface, each projection defining an engagement surface and a stop surface for engaging with respective tabs provided on a cover assembly cover plate, and such that the adaptor and cover plate work as a unitary body for engagement with the attachment portion of the filter head.
  • a filter assembly comprising a filter element and a housing.
  • the housing may comprise a head part and a body part.
  • a filter element comprising a cover plate having an aperture, a filter media connected to the cover plate, and an adaptor detachably coupled to the cover plate and located within the aperture, the adaptor having a threaded internal cylindrical surface for engagement with an attachment portion of a filter head for axial translation therealong so as to attach the filter element to the filter head, the filter element further comprising a coupling arrangement for detachably coupling the adaptor to the cover plate, the adaptor being configured to engage with the cover plate by means of the coupling arrangement such that the adaptor and the cover plate act as a single unit, and such that the adaptor and cover plate translate axially along the attachment portion when in engagement with the attachment portion without any relative movement between the cover plate and the adaptor.
  • adaptor can be configured to be resistant to the out-of-plane deformation.
  • cover plate has an aperture in it, this can be made of less material which reduces its weight and the cost of manufacture.
  • the relative movement may comprise relative axial and/or lateral movement.
  • the aperture may be a circular aperture and the cover plate may be an annulus defining the circular aperture, the cover plate having an internal radius and an external radius.
  • the ratio of the internal radius to the external radius may be greater than 0.3 and less than 1. More preferably, the ratio may be between 0.4 and 0.9 and even more preferably between greater than 0.5 and/or less than 0.8. When this ratio is large, then the cover plate thickness can be kept small.
  • the cover plate may include a base plate, the thickness of which may be 10mm or less, and preferably between 1 and 8mm. This again, reduces weight and manufacturing costs.
  • the coupling arrangement may comprise a plurality of circumferentially-spaced locking tabs provided on the annulus and extending radially within the circular aperture and a plurality of spaced projections provided circumferentially around an external surface of the adaptor, each projection defining an engagement surface and a stop surface, the locking tabs being configured to engage with a respective projection via the engagement surface and the stop surface to define the coupling arrangement for detachably coupling the adaptor to the cover plate.
  • the coupling arrangement may comprise a bayonet coupling.
  • the bayonet coupling may comprise the projections defining an engagement surface and the stop surface and the locking tabs.
  • the spaced projections may include a return tab defining a space between the return tab and the stop surface.
  • the locking tabs may have a radial depth of between 1mm and 6mm.
  • the locking tabs may have an angular width of greater than 25°.
  • the angular width may be between 25° and 170°, and more preferably between 35° and 160°.
  • the cover plate includes an annular sealing arrangement positioned at a radial distance.
  • the ratio of the radial distance of the annular sealing arrangement to the external radius may be greater than 0.6 but less than 1.0.
  • the cover plate may comprise a retainer plate mounted on the base plate.
  • the locking tabs may be formed on the base plate.
  • the retainer plate may include circular groove into which the sealing arrangement is provided. Because the adaptor is thick enough to withstand high pressure load scenarios, the sealing arrangement can be placed towards the outer circumference of the cover plate thus improving vibration frequency response and making the assembly more stable. This increases product life and stability. It also increases the amount of space available at the filter head to enclose additional components such as valves and heaters.
  • the adaptor may be a cylindrically-shaped body including an inner cylindrical hub with a plurality of spokes projecting therefrom and an outer ring portion.
  • the adaptor may have a thickness of less than 40mm and more preferably between 5mm and 30mm, more preferably between 10 and 25mm.
  • the inner cylindrical hub may be longitudinally displaced from the outer ring portion.
  • the filter media may be provided in a filter body, the filter body being connected to the underside of the cover plate.
  • the filter element may include a filter housing body part.
  • the body part may be a canister attached to the cover plate and may be attached to the retainer plate of the cover plate.
  • the filter element may include a positioning plate to position the filter body within the filter housing body part. A seal may be provided between the filter housing body part and the positioning plate, and around the spigot.
  • the positioning plate may include a plurality of radially-extending legs which abut the inner surface of the filter housing body part to thereby centralise the filter body within the filter housing body part.

Abstract

La présente invention concerne un élément filtre comprenant une plaque de couvercle (5) présentant une ouverture (7), une couche filtrante (6, 30) reliée à la plaque de couvercle, et un adaptateur (8) accouplé de manière amovible à la plaque de couvercle et situé à l'intérieur de l'ouverture. L'adaptateur présente une surface cylindrique interne (12) filetée. L'élément filtre comporte en outre un agencement d'accouplement (10) permettant d'accoupler de manière amovible l'adaptateur à la plaque de couvercle, l'adaptateur étant conçu pour venir en prise avec la plaque de couvercle au moyen de l'agencement d'accouplement de sorte qu'il n'y ait sensiblement pas de mouvement relatif entre la plaque de couvercle et l'adaptateur lorsque la plaque de couvercle et l'adaptateur sont en prise. La plaque de couvercle est reliée à une cartouche (4) qui loge la couche filtrante. L'adaptateur peut venir en prise avec un ergot (3) d'une tête de filtre au moyen du filetage interne de sorte qu'une rotation de la cartouche et donc de la plaque de couvercle et de l'adaptateur amène la plaque de couvercle et l'adaptateur à effectuer un mouvement de translation le long de l'ergot en vue d'amener la plaque de couvercle en liaison avec la tête de filtre. Un joint d'étanchéité (32) disposé sur la plaque de couvercle assure l'étanchéité entre la plaque de couvercle et la tête de filtre. La plaque de couvercle peut être détachée de l'adaptateur qui peut rester en place sur l'ergot afin de permettre le remplacement de la couche filtrante.
