Definitions

  • the present invention relates to fluid filters, and, more particularly, to oil and fuel filters. 2. Description of the related art.
  • Fuel and oil filters utilized in the automotive and trucking industry are typically of two types.
  • the first type is comprised of a reusable canister with a discardable inner filter assembly disposed therein.
  • the second type is a discardable filter comprised of an integral canister and inner filter assembly which are installed and removed as a unit.
  • Both the reusable and discardable type of filters include an elastomeric gasket at an axial face of the filter which seals against the housing to which the filter is engaged.
  • a threaded male portion attached to the housing threadedly engages a threaded female boss located in the filter for attaching the filter to the housing and axially squeezing the elastomeric seal between the filter and housing.
  • Conventional discardable fuel and oil filters typically include a canister which is attached to a cap. Disposed within the cap is an inner filter assembly for filtering the fuel or oil.
  • the elastomeric seal is attached to the external end face of the cap.
  • the cap includes a flange disposed at the radially outward periphery thereof which is joined with the canister by folding the two together during a rolling process. Because the rolled joint between the cap and canister is disposed radially outward from the elastomeric seal, two possible flow paths for fluid leakage are present in a discardable filter of conventional design.
  • Another oil filter structure involves folding the canister over the endcap and locating the elastomeric seal on the canister.
  • the elastomeric seal is axially pressed into the housing.
  • two potential leak paths exist, one between the elastomer seal and the canister, and the other between the elastomeric seal and the housing.
  • the axial force pressing the elastomeric seal into contact is perpendicular to the radial forces urging the oil at the potential leak paths, and is no more reliable than other axially pressed elastomeric seals.
  • a problem with conventional fuel and oil filters is that the elastomeric seal is compressed in a direction generally transverse to the fluid pressure acting against the radially inward side of the elastomeric seal, and at most is only partially biased in a direction which is substantially opposite to the fluid pressure on the radially inward side of the seal.
  • the present invention provides a fluid filter having a canister which directly contacts the housing and provides a high integrity contact therebetween. Thus, only a single potential leakage flow path is present, which may be sealed by plastic deformation of the material one of the canister or housing. Even without a seal created by plastic deformation, an annular seal may be disposed between the housing and canister to provide a seal therebetween which is enhanced by the surface-to-surface contact of the canister and the housing.
  • the present invention provides a fluid filter arrangement which has an increased sealing capability as a result of fluid pressure within the filter. With a conventional filter, an elastomeric seal is disposed at the end face of the filter and is axially squeezed between the housing and filter.
  • the fuel or oil to be filtered is pressurized and, thus, the fuel or oil disposed within the filter exerts a radially outward force on the radially inward side of the elastomeric seal. Since there is no structure at the radially outward side of the elastomeric seal at a location adjacent the leakage flow path, the radially outward force exerted against the seal by the fluid under pressure within the canister increases the likelihood of leakage between the elastomeric seal and the housing.
  • the present invention provides a surface-to-surface contact between a portion of the canister and the housing, which may be in the form of a metal-to-metal contact.
  • the canister and the housing exert a substantially equal force against each other which is substantially orthogonal to the adjoining surface therebetween.
  • an additional force is exerted against the canister which is opposite to the force exerted by the housing against the canister. This additional force exerted against the canister by the pressurized fluid, and in turn against the housing by the canister, increases the sealing capability of the fluid filter arrangement.
  • the surface-to-surface contact may be the basis of an elastomer type seal with an embodiment of the present invention which utilizes an external coating.
  • the contacting portion of the canister has a plastic coating so that the coating forms a fluid tight seal with the housing.
  • the upper portion of the canister may be dipped in latex or a similar material so that the contacting portion of the canister has the plastic material for forming the seal.
  • This embodiment has similar advantages as the metal-to-metal contact seal, however less torque is required to form the seal in this embodiment.
  • the present invention provides an alignment mechanism, in the form of a protuberance, which contacts the axial face of the oil filter and aligns the canister so that the resulting surface-to-surface contact is substantially circular and the seal is reliable.
  • the present invention is also adaptable to the structure of conventional oil filters and conventional housings.
  • An adapter for attaching oil filters of the present invention to existing engine housings consists of a head which resembles the present invention's housing design, with the head being connected to a base which assembles to the existing housing in the conventional manner.
  • An adapter for attaching an engine housing of the present invention to a conventionally designed oil filter consists of a disk which has an outer contacting edge for engaging the housing and an axial facing surface for contacting the annular axial seal of the conventional oil filter.
  • the invention comprises, in one form thereof, a fluid filter arrangement having a filter assembly connected to a housing.
  • the filter assembly includes a canister and means for axially biasing the filter assembly against the housing. A portion of the canister directly contacts the housing and by plastic deformation forms a fluid-tight seal therebetween.
  • the invention comprises, in another form thereof, a fluid filter arrangement having a filter assembly connected to a housing.
  • the filter assembly includes a canister and means for axially biasing the filter assembly against the housing.
  • An annular seal is disposed in an annular groove defined by the canister. A portion of the canister contacts the housing to enhance the sealing action of the annular seal.
  • the present invention in another form thereof, provides a fluid filter arrangement with a filter assembly connected to a housing.
  • the filter assembly includes a cap with a radially outward periphery, a canister attached to the cap's periphery, and means for axially biasing the filter assembly against the housing.
  • a portion of the canister directly contacts the housing to form a surface-to-surface contact.
  • An annular seal is disposed in an annular groove defined by one of the cap and the canister.
  • An advantage of the present invention is that a surface- to-surface seal is created by plastic deformation between the fluid filter and housing.
  • an O-ring may also be provided to form a seal which is enhanced by the surface-to-surface contact between the fluid filter and housing.
  • O-ring is biased at least in part in a radially inward direction, thereby counter-acting fluid pressure exerted against the O-ring.
  • portion of the canister engaging the housing is biased toward the housing with fluid pressure within the canister under operating conditions.
  • a smaller torque is required to seal the fluid filter with the housing, relative to conventional filters utilizing axially compressed seals.

As shown in Figure 3, canister 34 is rolled, stamped, or otherwise deformed to mate with radially outward periphery 46. A portion of canister 34 is formed into annular groove 48 and substantially conforms to the contour of annular groove 48, thereby defining another annular groove 50.

  • Layer 122 may be any type of polymer material, such as latex, rubber, or other suitable plastically deformable material with a suitable durometer. With this arrangement, the material of canister 114 may be of a harder constitution than desired to form a contact seal with housing annular surface 64, and the material of layer 122 has a greater ability to plastically deform so that layer 122 forms the surface-to-surface seal. Also, as layer 122 has elastomeric sealing properties similar to that of an o-ring, an o-ring is unnecessary with the embodiment of Figure 14. However, this embodiment may optionally include an o-ring disposed in an annular groove which would provide additional sealing to further secure the interface.

  • housing 60 may include protuberance 124 which extends circumferentially through chamber 70.
  • cap 36 approaches protuberance 124. If canister 34 is not properly aligned with housing 60, one end of cap 36 will contact protuberance 124 while an elliptical line of contact is formed. Further axial movement by the contacting end of cap 36 will be prevented by protuberance 124, so that the further axial movement will cause cap 36 to axially align itself and decrease the eccentricity of the elliptical line of contact.
  • Protuberance 124 may be in the form of an annular-wall extending around the outer periphery of chamber 70, or alternatively protuberance 124 may be in the form of a series of circumferentially disposed projections which define a plane which is generally orthogonal to the axis of male threaded portion 62 of housing 60.

  • Bead 134 provides a surface for contacting annular surface 64 of housing 60 to form the surface-to-surface seal supporting the primary seal provided by annular seal 58.
  • This beaded embodiment provides a point or line contact which allows for high unit loading, and is also desirable because the manufacture of bead 134 may be readily accomplished.

  • the potential fluid leakage flow path thus extends from chamber 70 to the ambient environment.
  • the surface-to-surface or annular seal which is disposed upstream of the other, with respect to the direction of fluid flow is referred to as the "primary" seal or contact point and the seal disposed downstream is referred to as the "secondary" seal or contact point.

Abstract

L'invention concerne un système filtrant pour liquide comportant une unité filtrante reliée à un boîtier. L'unité filtrante comprend un couvercle dont le contour extérieur s'étend radialement, une cartouche fixée au contour extérieur radial du couvercle et un système qui permet de solliciter l'unité filtrante contre le boîtier dans le sens axial. Une partie de la cartouche touche directement le boîtier et forme un contact de surface à surface qui sert de base à une garniture d'étanchéité résultant de la déformation plastique du boîtier ou de la cartouche ou se présentant sous forme de joint pourvu d'un revêtement plastique. Une autre solution consiste à ce qu'une garniture d'étanchéité annulaire comprenant un élastomère soit introduite dans une rainure annulaire délimitée par le contour extérieur radial du couvercle et la cartouche, de manière à ce que le contact de surface à surface renforce l'étanchéité de l'élastomère. L'invention concerne en outre des adaptateurs qui permettent d'utiliser le filtre à huile réalisé selon l'invention avec un boîtier traditionnel et d'utiliser le boîtier de la présente invention avec un filtre traditionnel.
