Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This PCT application claims the benefit of and priority to Indian Provisional Application No. 202241059559 filed on October 18, 2022, the contents of which are incorporated herein by reference in their entirety.
[0003] field
[0004] The present application generally relates to fluid filter assemblies for supplying filtered fluid to downstream devices.
[0005] background
[0006] Internal combustion engines typically combust a mixture of fuel (e.g., diesel, gasoline, natural gas, etc.) and air. Prior to entering the engine, the fuel is typically passed through a filter cartridge to remove particulate matter (e.g., dust, metal particles, debris, etc.) from the fuel prior to combustion. Similarly, the lubricant or lubricating oil (e.g., engine oil) provided to the engine may also pass through a filter cartridge to remove particulate matter from the lubricating oil prior to delivery to the engine.
[0007] A filter element (e.g., a filter cartridge) typically includes a sealing feature that forms a seal between the filter element and the filter head. The seal prevents fluid from bypassing the filter element (e.g., preventing air from bypassing an air filter element or preventing liquid from bypassing a liquid filter element). In many filtration systems, if a filter element is not installed, unfiltered fluid may damage downstream components. Therefore, failure to install a filter element or installation of an incompatible filter element may damage critical components in the filtration system, reduce emission compliance mechanisms, result in performance below expected standards, etc.
[0008] Overview
[0009] Various embodiments provide a filter assembly. The filter assembly includes a filter head and a filter cartridge. The filter head includes a first port and a valve positioned within the first port. The filter cartridge includes a housing having a housing wall defining an interior volume and a filter element disposed within the interior volume. The filter element includes a filter medium and a first end plate coupled to the filter medium at a first end of the filter medium. The first end plate includes an end plate end wall and an arm extending axially away from the end plate end wall such that the arm contacts the valve.
[0010] Various other embodiments provide a filter head assembly. The filter head assembly includes a filter head, the filter head includes a port and a valve disposed in the port. The valve includes a valve wall, a first side wall extending away from the valve wall in a first direction, a second side wall extending away from the valve wall in the first direction, and a column extending away from the valve wall in a second direction opposite to the first direction.
[0011] Various other exemplary embodiments provide a method of installing a filter cartridge with a filter head. The method includes rotating the filter cartridge relative to the filter head so that the housing threads of the housing of the filter cartridge engage the filter head threads of the filter head; and contacting the prongs of the filter head with the ribs of the end plate of the filter cartridge to prevent the end plate of the filter cartridge from further rotating relative to the filter head.

[0055] Detailed Description
[0056] Embodiments described herein generally relate to a no-filter no-run filter assembly. According to various embodiments, the no-filter no-run filter assembly includes a no-filter no-run feature configured to operably prevent a downstream device, such as an engine, from operating when a filter element is not installed or when an unauthorized filter element is installed. The no-filter no-run feature can advantageously improve ease of maintainability by ensuring that an authorized filter element is properly installed within the filter assembly.
[0057] Before turning to the drawings, various embodiments of the filter-free no-run filter assembly and its components are described herein. It should be understood that although the various components are described in detail, these details should be considered as examples only. In addition, the details may include variations described herein. Therefore, it should be understood that although the various components can be described with respect to the embodiments, unless otherwise stated, any component can be used in any other embodiment described herein.
[0058] refer to Figure 1A and Figure 1B, shows a perspective view of a filter assembly 100 according to an example embodiment. Figure 1A As shown, the filter assembly 100 includes a filter head 102 and a filter cartridge 200. Figure 1B As shown, the filter assembly 100 may further include a pump 106 disposed at the filter head 102. It should be understood that the filter assembly 100 may include more than Figure 1A and Figure 1B More or fewer components than shown.
[0059] The filter head 102 includes one or more ports 104. At least one of the ports 104 is an inlet that is in fluid receiving communication with an upstream device (e.g., a fluid pump, a fluid storage tank, etc.). For example, the inlet provides dirty or unfiltered fuel to the filter assembly 100. At least one of the ports 104 is an outlet that is in fluid providing communication with a downstream device (e.g., an engine). For example, the outlet provides filtered fuel to a downstream component, such as an engine. The filter head 102 may include a pump 106. The pump 106 is configured to enable receiving and / or providing fluid through one or more of the ports 104.
[0060] Figure 2A yes Figure 1B 1. A cross-sectional view of a portion of a filter assembly 100 is shown in FIG. 1. The filter assembly 100 includes a filter head assembly and a filter cartridge 200. The filter head assembly includes a filter head 102 and a valve 130. The filter cartridge 200 includes a housing 210 and a filter element 218. Figure 2B is a perspective view of filter element 218 .
[0061] Filter head 102 includes filter head wall 110 and one or more inwardly facing threads shown as filter head threads 114. Filter head threads 114 are configured to receive one or more outwardly facing threads, such as housing threads 214 of housing 210 shown.
[0062] The filter head wall 110 defines a valve port 120 proximate to at least one of the ports 104 such that the valve port 120 is in fluid communication with at least one of the ports 104. The valve port 120 is configured to receive a valve 130 therein such that the valve 130 is at least partially contained within the valve port 120. The valve 130 is operable between an open position and a closed position. In some embodiments, a sealing member 150 may be positioned within the valve port 120, such as Figure 2AAs shown. The sealing member 150 may be a plastic member configured to contact the valve 130 and form a seal therebetween when the valve 130 is in the closed position. The valve port 120, the valve 130, and the sealing member 150 are described in further detail below.
[0063] The filter head wall 110 defines a fork 118 that extends axially toward the filter element 218. The fork 118 is described in further detail below.
[0064] The filter head wall 110 defines a pump port 112. The pump port 112 is configured to receive at least a portion of the filter element 218 therein. The pump port 112 defines a filter head sealing surface 113. The filter head sealing surface 113 is configured to form a first circumferential, radially-directed seal with a sealing member 190 (e.g., an O-ring gasket, etc.).
[0065] The filter head wall 110 defines a recess 164 that is located distally from the valve port 120 (eg, diametrically opposite the valve port 120 ). The recess 164 is configured to receive at least a portion of the filter element 218 .
[0066] The housing 210 includes a housing wall 212 and one or more housing threads 214 extending radially outwardly away from the housing wall 212. The housing 210 defines an internal volume such that the housing 210 is configured to receive a filter element 218 at least partially within the internal volume. The housing 210 is removably coupled to the filter element 218. The coupling between the housing 210 and the filter element 218 will be described in further detail below.
[0067] like Figure 2B As shown, filter element 218 includes filter media 220 mounted between a first end plate 230 and a second end plate 250. For example, first end plate 230 is coupled to filter media 220 at a first end of the filter media, and second end plate 250 is coupled to filter media 220 at a second end of the filter media opposite the first end. Filter media 220 may include one or more media layers, such as pleated and / or woven filter media, a hydrophobic screen, and / or any other suitable filter media layer.
[0068] like Figure 2AAs shown, the first end plate 230 includes an end plate end wall 231, a filter medium channel 232 extending axially in a first direction away from the end plate end wall 231 toward the filter medium 220, an end plate port 240 extending axially in a second direction opposite to the first direction away from the end plate end wall 231 and toward the filter head 102, and a first coupling member 270 extending radially away from the end plate end wall 231. The filter medium channel 232 is configured to receive at least a portion of the filter medium 220 so that the filter medium 220 is coupled to the end plate 230.
[0069] The end plate port 240 is configured to enable fluid communication between the interior volume of the filter element 218 and the pump port 112. The end plate port 240 includes a sealing channel 242 extending radially outward toward the pump port 112. The sealing channel 242 is configured to at least partially retain the sealing member 190 therein so that the sealing member 190 forms a seal between the filter head sealing surface 113 and the sealing channel 242. The end plate port 240 also includes a rib 244 extending across the diameter of the end plate port 240. In some embodiments, the rib 244 may include one or more traverse portions. The fork 118 may extend through the pump port 112 and the end plate port 240 so that a portion of the rib 244 (e.g., the traverse portion) contacts the fork 118. Fig. 9A and Fig. 9B The ribs 244 are described in more detail.
[0070] The first coupling member 270 is configured to couple the filter element 218 to the housing 210. In some embodiments, the first coupling member 270 can couple the filter element 218 to the housing 210 in a snap-fit arrangement. In some embodiments, the first coupling member 270 can fix the filter element 218 in an axial direction and a radial direction relative to the housing 210, and allow the filter element 218 to move in a circumferential (e.g., rotational) direction relative to the housing 210.
[0071] The first end plate 230 also includes a first arm 260 and a second arm 264 that extend axially in a first direction away from the end plate end wall 231 toward the filter head 102. The first arm 260 is positioned such that the first arm 260 is at least partially received by the valve port 120. The first arm 260 is configured to contact a portion of the valve 130 and bias the valve 130 to an open position. The second arm 264 is positioned diametrically (or substantially diametrically) opposite the first arm 260 such that the second arm 264 is received by the recess 164. It should be understood that as Figure 2AThe illustrated positioning of the first arm 260 relative to the second arm 264 is shown only as an example. In additional and / or alternative embodiments, the first arm 260 and the second arm 264 can have different positioning relative to each other. The first arm 260 and the second arm 264 are described in further detail below.
[0072] Reference now Figure 3A and Figure 3B , shows a perspective view of the filter head 102. Figure 3A As shown, filter head 102 includes valve port 120 and pump port 112. Pump port 112 can be in fluid communication with at least one of ports 104 and / or pump 106. Figure 3B As shown, the valve port 120 includes a closed end defined by a valve port wall 121 and an open end defined by a valve port opening 122. The valve port 120 includes an annular wall 123 extending away from the valve port wall 121 toward the valve port opening 122. The valve port 120 also includes a valve port sidewall 124 extending between the valve port wall 121 and the valve port opening 122. The valve port sidewall 124 includes one or more openings 125 so that the valve port 120 is in fluid communication with one or more ports 104. The valve port 120 also includes one or more protrusions 126 extending radially inward from the valve port sidewall 124.
[0073] Reference now FIG. 4A to FIG. 4C , showing an example embodiment of the invention that can be used Figure 1B 100. The valve 130 may be made of a plastic material, a metal material (e.g., steel), or any other suitable material. The valve 130 includes a valve wall 131, a valve first side wall 132 extending away from the valve wall 131 in a first direction, and a valve second side wall 134 diametrically opposite to the valve first side wall 132 and extending in the first direction. The valve first side wall 132 is spaced apart from the valve second side wall 134 so that a channel 138 is defined between the valve first side wall 132 and the valve second side wall 134. The channel 138 is in fluid communication with one or more ports 104. The valve 130 also includes a column 140 extending away from the valve wall 131 in a second direction opposite to the first direction.
[0074] The valve first side wall 132 includes one or more recesses 133. The valve second side wall 134 includes one or more recesses 135. The one or more recesses 133, 135 are configured to receive one or more protrusions 126 of the valve port 120, so that the valve 130 is fixed relative to the valve port 120 in the radial direction and the rotational direction, and is free to translate in the axial direction.
[0075] The post 140 includes a first rib 142, a second rib 144, and a third rib 146. The first rib 142 extends axially away from the bottom surface 139 of the valve wall 131. The second rib 144 extends axially away from the bottom surface 139 of the valve wall 131 and is substantially perpendicular to the first rib 142. The third rib 146 is spaced apart from the bottom surface 139 of the valve wall 131 and is substantially parallel to the bottom surface 139 and perpendicular to the first rib 142 and the second rib 144. The first rib 142 extends farther away from the bottom surface 139 than the second rib 144, such that the distal end of the first rib 142 extends beyond the distal end of the second rib 144. The third rib 146 is positioned between the bottom surface 139 and the distal end of the second rib 144. The width of the third rib 146 is less than the width of the first rib 142. The first rib 142, the second rib 144, and the third rib 146 advantageously provide structural rigidity to the post 140 such that the post 140 is substantially prevented from deflecting relative to the bottom surface 139.
[0076] Reference now Figure 4D , a cross-sectional perspective view of an example sealing member 150 that can be used in the filter assembly 100 is shown. The sealing member 150 includes a sealing surface 152. As briefly described above, the sealing member 150 can be positioned within the valve port 120 so that when the valve 130 is in the closed position, the sealing surface 152 contacts the bottom surface 139 of the valve 130. The sealing surface 152 forms a radial seal with the bottom surface 139 of the valve 130. The sealing member 150 can be made of a plastic material, a metal material, and / or other suitable materials.
[0077] Reference now FIG. 5A to FIG. 5D , various views of the filter assembly 100 are shown without a genuine filter element (e.g., filter element 218). When the filter element 218 is not installed in the filter assembly 100, or when a non-genuine filter element 219 is installed in the filter assembly 100, the valve 130 is biased away from the valve port wall 121 (e.g., downward) by the pressure of the fluid flowing through the port 104. More specifically, the fluid flowing through the port 104 can enter the valve port 120 and flow into the channel 138. The pressure of the fluid can bias the valve 130 to a closed position. In the closed position, the valve 130 forms a radial seal with the sealing member 150. When a non-genuine filter element 219 is installed in the filter assembly 100, the valve 130 advantageously prevents fluid (e.g., fuel) from flowing from the port 104 into the filter cartridge 200. As Figure 5D As shown, when the valve 130 is in the closed position, the passage 138 may be aligned with the port 104 such that fluid may flow from the port 104 and through the passage 138 .
[0078] Reference now FIG. 6A to FIG. 6C, various views of the filter assembly 100 with the filter element 218 are shown. When the filter element 218 is installed in the filter assembly 100, the valve 130 is biased away from the valve port wall 121 (e.g., upward) by the first arm 260. More specifically, the arm 260 contacts the post 140 and biases the valve 130 to an open position. In the open position, the valve 130 does not form a radial seal with the sealing member 150, and allows fluid to flow from the port 104 into the valve port 120 and into the filter element 218. When the genuine filter element 218 is installed in the filter assembly 100, the valve 130 advantageously allows fluid (e.g., fuel) to flow from the port 104 into the filter cartridge 200.
[0079] like Figure 6C As shown, the arm 260 includes an arm channel 262 that receives the distal end of the first rib 142 such that the distal end of the first rib 142 contacts the bottom surface of the channel 262 and the distal end of the second rib 144 contacts the top surface of the channel 262. The arm channel 262 substantially prevents the valve 130 from deflecting relative to the arm 260.
[0080] Reference now Fig. 7A , a perspective view of an end plate 230 according to an example embodiment is shown. As briefly described above, the end plate 230 includes an end plate end wall 231, an end plate port 240, a first arm 260, and a second arm 264. The first arm 260 includes a first arm channel 262. The second arm 264 includes a second arm channel 266. The end plate 230 also includes a first coupling member 270 and a second coupling member 280. A radial flange 272 extends radially away from each first coupling member 270. The radial flange 272 can enable the end plate 230 to be coupled to the housing 210. The second coupling member 280 may include one or more protrusions extending radially away from the end plate end wall 231. When the end plate 230 is coupled to the housing 210, the second coupling member 280 contacts the top surface of the housing 210 so that the coupling member 280 substantially prevents the end plate 230 from translating toward the housing 210 (e.g., downward).
[0081] As briefly described above, the end plate 230 also includes an end plate port 240. The end plate port 240 enables fluid communication between the interior volume of the filter element 218 and the pump port 112. The end plate port 240 includes a sealing channel 242 and a rib 244. The rib 244 includes one or more transverse portions shown as a first transverse portion 245, a second transverse portion 246, and a third transverse portion 247. As shown, the first transverse portion 245 is substantially parallel to the third transverse portion 247, and the second transverse portion 246 is inclined relative to the first transverse portion 245 and the third transverse portion 247.
[0082] Reference now Figure 7B, shows a perspective view of a portion of a housing 210 according to an example embodiment. The housing 210 includes a housing passage 216 defined on an inner surface of the housing wall 212. The housing passage 216 is configured to receive a radial flange 272 of the end plate 230 when the end plate 230 is coupled to the housing 210.
[0083] Figure 7C is a perspective view of filter element 218 including end plate 230 installed in housing 210 .
[0084] Reference now FIG. 8A to FIG. 8C , various views of a filter cartridge 200 are shown according to an exemplary embodiment. Specifically, FIG. 8A to FIG. 8C Filter element 218 is shown coupled to housing 210. Figure 8C As shown, the radial flange 272 of the first coupling member 270 is received by the housing passage 216, so that the filter element 218 is coupled to the housing 210. As briefly described above, the housing passage 216 can receive the radial flange 272 in a snap-fit arrangement. When the housing passage 216 receives the radial flange 272, the housing passage 216 substantially prevents the radial flange 272 from moving in the axial direction and the radial direction, and enables the radial flange 272 to translate circumferentially within the housing passage 216, so that the filter element 218 can rotate relative to the housing 210.
[0085] Reference now Fig. 9A and Fig. 9B , shows a cross-sectional view of a filter cartridge 200 shown installed in a filter head 102. Fig. 9A and Fig. 9B As shown, the filter head threads 114 engage the housing threads 214 such that the filter cartridge 200 is threadably coupled to the filter head 102. When the filter head threads 114 engage the housing threads 214, the forks 118 are received by the end plate ports 240 such that the forks 118 contact the ribs 244. When the housing 210 is rotated to engage the housing threads 214 to the filter head threads 114, the forks 118 substantially prevent the end plate 230 from rotating. It should be understood that the filter head 102 can be rotated relative to the housing 210 such that when the housing threads 214 engage the filter head threads 114, the forks 118 rotate the end plate 230 relative to the housing 210.
[0086] Reference now FIG. 10A to FIG. 10C , shows a cross-sectional view of a portion of the filter assembly 100 in an assembled state. As shown, the fork 118 is received by the end plate port 240 so that the fork 118 contacts the rib 244. The first rib 142 is received by the arm channel 262 so that the post 140 is substantially prevented from moving relative to the arm 260.
[0087] FIG. 11A to FIG. 11Bis a cross-sectional view showing a portion of a filter assembly 100 according to an exemplary embodiment. The filter head 102 may include a valve port 310 configured to receive the valve assembly 300. The valve port 310 is in fluid communication with at least one of the interior volume of the housing 210 and the port 104. In an exemplary embodiment, the valve port 310 is in fluid communication with the port 104, and the port 104 is in fluid communication with a fluid source (e.g., a fuel tank). The valve port 310 defines a valve port sealing surface 308.
[0088] The valve assembly 300 includes a valve body 302 and a valve sealing member 304. The valve assembly 300 is operable between an open position and a closed position. In the open position, the valve assembly 300 allows fluid (e.g., fuel, unfiltered fuel) to flow from the interior volume of the housing 210 to the port 104. The fluid then flows from the port 104 to a downstream component (e.g., a fluid source, a fuel tank). In the closed position, the valve sealing member 304 contacts the valve port sealing surface 308 and forms an axial seal therebetween, substantially preventing fluid from flowing from the interior volume of the housing 210 to the port 104. The valve assembly 300 may be biased to the open position by a biasing member (shown as a spring 312).
[0089] like Fig.11A As shown, when a genuine filter element 218 is not installed in the filter assembly 100, the valve assembly 300 is biased to an open position by the spring 312. When a non-genuine filter element is installed in the filter assembly 100, the valve assembly 300 advantageously allows fluid (eg, fuel) to flow back to the fluid source.
[0090] like Fig. 11B As shown, when the genuine filter element 218 is installed in the filter assembly 100, the arm 264 contacts the valve body 302 and biases the valve assembly 300 to a closed position (e.g., by compressing the spring 312). When the genuine filter element 218 is installed in the filter assembly 100, the valve assembly 300 advantageously allows the fluid (e.g., fuel) to be filtered by the filter element 218.
[0091] In some embodiments, when the genuine filter element 218 is installed in the filter assembly 100, an opening is defined between the end plate 230 and the valve body 302, allowing at least a portion of the fluid (e.g., fuel and / or air) to flow through the valve port 310. In these embodiments, only a portion of the fuel provided to the filter element 218 flows through the opening defined between the end plate 230 and the valve body 302.
[0092] Reference now Fig. 12A and Fig. 12B , shows a cross-sectional view of a portion of a filter assembly 100 according to another embodiment. Fig. 12A and Fig. 12B As shown, a biasing member, shown as a spring 320, may be positioned within the valve port 120. Fig. 12A As shown, when the genuine filter element 218 is not installed and / or when the non-genuine filter element 219 is installed in the filter assembly 100, the spring 320 biases the valve 130 to the closed position. Fig. 12B As shown, when the genuine filter element 218 is installed, the arm 260 contacts the post 140 of the valve 130 and biases the valve 130 to an open position (eg, by compressing the spring 320).
[0093] In some embodiments, the sealing member 150 includes a second sealing member, shown as an O-ring 322 (e.g., a gasket, etc.). When the valve 130 is in the closed position, the O-ring 322 contacts the valve 130 and the sealing member 150 and forms a radial seal between the valve 130 and the sealing member 150. The radial seal formed by the O-ring 322 substantially prevents fluid from flowing from the port 104 into the filter cartridge 200. When the valve 130 is in the open position, the O-ring 322 does not contact the valve 130, and fluid can flow between the valve 130 and the O-ring 322.
