DETAILED DESCRIPTION
[0031] The present disclosure relates to a filter assembly.
[0032] In a particular example, the power source 18 includes an engine configured to combust a fuel such as diesel and this fuel is filtered at a filter assembly 30. As fuel passes through the filter assembly 30, contaminants such as water, debris, and the like are filtered out and collect in the filter assembly 30. Periodically, the filter assembly 30 is inspected to determine if a filter medium (described further herein) disposed within the filter assembly 30 should be replaced. For example, if sufficient debris has collected on the filter medium, the filter medium may be replaced. As described herein, it is an advantage of aspects of the filter assembly 30 that the filter assembly 30 is easier and less time consuming to inspect and replace the filter medium than conventional filter cartridges. These and other advantages are described herein. Of note, while particular example is made throughout of filtering fuel, the various aspects are not limited to filtering fuel, but rather, include any suitable filtering application. Examples of suitable filtering applications include hydraulic, lubricant, air, or other such filtration systems.
[0033]
[0034] The filter assembly 30 includes a first component or a base 32 and a second component or a housing 34 that are detachably coupled together. As shown in
[0035] Also shown in
[0036]
[0037] The filter assembly 30 further includes a filter element 106 housed at least partially within the housing 34. In an aspect, the filter element 106 is removably received within the housing 34, such as in a canister type filter assembly. Alternatively, the filter element 106 is fixedly received within the housing 34.
[0038] The base 32 includes the inlet port 36 and the outlet port 38. The filter element 106 is configured to be in fluid communication with the inlet port 36 and the outlet port 38. The inlet port 36 is configured to facilitate fluid intake into the filter assembly 30. The outlet port 38 is configured to facilitate fluid discharge from the filter assembly 30. The base 32 further includes a stepped portion 112 having a first groove 114 disposed therein. In an aspect, the first groove 114 may be a continuous annular groove disposed on an inner surface 116 of the stepped portion 112 of the base 32. Alternatively, the first groove 114 may be a discontinuous groove forming a cavity located on the inner surface 116 of the stepped portion 112. Further, the first groove 114 may have a substantially rectangular cross-section. Alternatively, the first groove 114 may have any other cross-sectional shape, such as circular, triangular, and the like. In an aspect, the first groove 114 may have a height H1 and a width W1 as shown in
[0039] Further, the housing 34 includes a top end 118 and a bottom end 120. The top end 118 includes a stepped portion 122 configured to be attached to the base 32. The stepped portion 122 of the housing 34 includes a second groove 124 disposed therein. The second groove 124 is located on an outer surface 126 of the housing 34. In an aspect, the second groove 124 may be a continuous annular groove located on the outer surface 126 of the housing 34. Alternatively, the second groove 124 may also be a discontinuous groove forming a cavity similar to the one formed by the first groove 114 as explained above. The second groove 124 may have a height H2 and a width W2 as shown in
[0040] In an aspect, the first groove 114 and the second groove 124 have substantially similar cross-sections. For example, similar to the first groove 114, the second groove 124 may also have a substantially rectangular cross-section. Alternatively, the second groove 124 may have any other cross-sectional shape, such as circular, triangular, and the like. In an exemplary aspect, the height H2 of the second groove 124 may also be equal to the height H1 of the first groove 114.
[0041] The filter element 106 includes a filter media 128 that may be arranged annularly about a central reservoir defined by a central tube 130. Axial ends of the filter media 128 are sealed by a top end cap 132 and a bottom end cap 134. The top end cap 132 defines an axial open end of the filter element 106. The bottom end cap 134 defines an axial closed end of the filter element 106. The top end cap 132 includes an opening (not shown) configured to facilitate passage of fluid to the outlet port 38 from the central tube 130. The bottom end cap 134 is configured to prevent any fluid outside the filter element 106, adjacent to the axial end of the filter media 128, from flowing unfiltered into the central tube 130. The top end cap 132 and the bottom end cap 134 may be joined to the central tube 130 by welding, adhesives, mechanical coupling, etc. Alternatively, some or all of the central tube 130, the top end cap 132, and the bottom end cap 134 may be constructed as unitary components.
[0042] Fluid to be filtered enters from the inlet port 36 and flows into an annular cavity 136 between the housing 34 and the filter media 128. The fluid passes into and through the filter media 128 and then into the central tube 130 via perforations 138 provided in the central tube 130. The fluid exits the central tube 130 through the top end cap 132 and the opening into the outlet port 38.
[0043] Furthermore, the filter assembly 30 includes a drain 140 releaseably coupled to the bottom end 120 of the housing 34. The drain 140 provides a channel for removing the fluid inside the housing 34. An inlet end (not shown) of the drain 140 is positioned within the housing 34 and an outlet end 144 of the drain 140 is positioned outside the housing 34. The drain 140 may be moved between an open and a closed position. It may be contemplated that in the open position, the fluid within the housing 34 may be drained out via the outlet end 144 of the drain 140.
[0044] Referring to
[0045] The cord member 40 is configured to form a connection 148 between the base 32 and the housing 34. The connection is formed by removably inserting the cord member 40 in the channel 142 between the first groove 114 and the second groove 124. Essentially, by filling the channel 142 cord member 40 locks the first groove 114 and the second groove 124 together and prevents the base 32 from moving relative to the housing 34. The cord member 40 is inserted and/or drawn outwardly from the filter assembly 30 to lock and/or unlock, respectively, the housing 34 with the base 32. The catch assembly 44 and the first detent 52 are configured to facilitate retaining the cord member 40 in
[0046] In an aspect, the cord member 40 may be a spline made up of a deformable material, such as rubber, so that when inserted in the channel 142, the cord member 40 may be deformed to fit into the channel 142. Therefore, in this aspect, a width W and/or a height H of the cord member 40 may be substantially equal to a width W3 and/or the height H3 of the channel 142 (shown in
[0047] The cross-section of the cord member 40 is substantially similar to the cross-section of the channel 142, the first groove 114 and the second groove 124. For example, the cross-section of the cord member 40 may be substantially rectangular, circular, etc. In addition, the cord member 40 may be textured or beaded with the beads running along the axis of the cord member 40 or perpendicularly across the cord member 40.
[0048] The base 32 may include a gasket seat 154 and the housing 34 may include a gasket seat 156. A gasket 164 may be disposed between the gasket seat 154 and the gasket seat 156 to form a seal. In order to seat the gasket 164 between the gasket seat 154 and the gasket seat 156, a predetermined amount of compressive force may be applied to base 32 and the housing 34. This predetermined amount of compressive force may depend upon a variety of factors such as, for example, fluid viscosity, fluid pressure, size of the gasket 164, material properties of the gasket 164, and the like.
[0049]
[0050]
[0051] The first detent 52 includes a stop surface 72 and a first sloped surface 74. As shown in
[0052]
[0053] Referring to
[0054] Optionally, the cord member 40 may be removed from the catch assembly 44. For example, the release 48 may be used to retract the catch 60 from the first detent 52 to allow the cord member 40 to be withdrawn from the catch assembly 44. In a particular example, the release 48 may be configured to accept a tool bit (not shown) and the release 48 may be unthreaded from the catch assembly 44.
INDUSTRIAL APPLICABILITY
[0055] The present disclosure may be applicable to any machine including a fluid filter housing assembly. Aspects of the disclosed filter housing assembly may promote ease of use, operational flexibility, and performance of fluid filter housing assemblies in general and fuel systems in particular. In some examples, the cord member 40 may include both the first detent 52 and the second detent 54. However, in other examples, the cord member 40 may include one or the other of the first detent 52 and the second detent 54. As described herein, both the first detent 52 and the second detent 54 are configured to resist or arrest motion of the cord member. More particularly, the first detent 52 and the second detent 54 provide resistance to movement of the cord member 40 relative to the catch assembly 44. More particularly still, the first detent 52 is configured to interact with the catch assembly to substantially prevent removal of the cord member 40 from the catch assembly 44 while the second detent 54 is configured to interact with the catch assembly 44 to resist movement of the cord member 40 relative to the catch assembly until a predetermined amount of force is applied to the cord member.
[0056] The industrial applicability of the filter assembly 30 for filtering fluids and the cord member 40 will be readily understood from the foregoing discussion. The catch assembly 44, the first detent 52, and the second detent 54 of cord member 40 facilitates retaining the cord member 40 in the catch assembly 44 and securing the cord member 40 in a connected configuration. The base 32, the housing 34 and the filter element 106 may be easily disassembled by removing the cord member 40, for example to clean or change the filter element 106. The second detent 54 and the action of the catch assembly 44 provide a retentive force to further retain the cord member 40 in the channel 142 and secures the connection 148 (see
[0057] The configuration and the components of the filter assembly 30 as disclosed herein may be used in any type of filters, such as canister type or spin-on type of filters. The housing 34 and the filter element 106 may collectively be called as a replacement component of the filter assembly 30, where the replacement component may be replaced or at least detached from the base 32 for replacing the one or more components of the same.
[0058] Additionally, the stepped portion 112 of the base 32 and the stepped portion 122 of the housing 34 may be locked by using any known releasable locking mechanism and the cord member 40 and channel 142 may be included as an additional connection of the two components. Furthermore, the filter assembly 30 is easy to manufacture, and is also cost efficient. Moreover, the filter assembly 30 as disclosed herein may be utilized in any shape and size of the filter assembly 30, such as for circular or non-circular shapes.
[0059] Accordingly, aspects of the disclosure facilitate increased resistance to inadvertent disassembly of the filter assembly 30 via removal of the cord member 40 from filter assembly 30. Aspects of the disclosure may also facilitate retention of the cord member 40 in the catch assembly 44 during disassembly, inspection/replacement of the filter element 106, and/or re-assembly of the filter assembly 30.
[0060] It will be appreciated that the foregoing description provides examples of the disclosed system and technique. However, it is contemplated that other implementations of the disclosure may differ in detail from the foregoing examples. All references to the disclosure or examples thereof are intended to reference the particular example being discussed at that point and are not intended to imply any limitation as to the scope of the disclosure more generally. All language of distinction and disparagement with respect to certain features is intended to indicate a lack of preference for those features, but not to exclude such from the scope of the disclosure entirely unless otherwise indicated.
[0061] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context.
[0062] Throughout the disclosure, like reference numbers refer to similar elements herein, unless otherwise specified.
