Furthermore, the base support 46 may be configured to have at least one base support opening 48, the base support opening 48 extends through the outer surface 40 to the inner surface 42 of the modified valve cover 38. Moreover, the base support opening 48 may be circular and positioned approximately in the center of the base support 46, however other configurations and locations are possible. Additionally, in some embodiments, the base support 46 may be further configured to support and/or mate with a filter element 50. For example, in some embodiments, the base support 46 may be sloped at a specified angle to provide a level support surface for the filter element 50 when the modified valve cover 38 is attached to the cylinder head 30, however other configurations are possible. In exemplary embodiments, the filter element 50 may be used to remove contaminants that accumulate in engine fluids (not shown) during operation of the engine 22. One non-limiting example of an engine fluid that may be filtered is engine oil, however other fluids such as, but not limited to, transmission fluid, engine coolant, fuel or other known fluids, may be filtered as well.
[0022] Moreover, in some embodiments, the filter element 50 may be a centrifugal filter, a cartridge filter, a spin-on filter or other known filter type. The filter element 50 may be disposed on the outer surface 40 of the modified valve cover 38 and removably attached to the base support 46 using one or more filter attachment points 52.

INDUSTRIAL APPLICABILITY
[0028] In general, the disclosed valve cover with integrated filter base of the present disclosure can find applicability in many industries, including but not limited to, engines used in the earth moving, mining, agricultural and construction industries. Such a valve cover may be configured to be compatible with any type of engine fluid filter. More specifically, the valve cover with integrated filter base may utilize available space within the engine compartment to provide a mounting base for an oil filtering system. One non-limiting example of an oil filtering method using the valve cover with integrated filter base is described below.
[0029] Referring to
[0030] According to the next step 98 of method 94, a filter element 50 may be removably attached to the base support 46 of the modified valve cover 38. Furthermore, the base support 46 may have an opening 48 extending from the outer surface 40 through the inner surface 42. In some embodiments, the filter element 50 is disposed on the outer surface 40 of the modified valve cover 38. Moreover, the filter element 50 may be positioned to at least partially overlap with the base support opening 48 when the filter element 50 is attached to the base support 46.
[0031] In a step 100, the fluid supply line 84 may be configured to deliver fluid to the engine block 82 and the filter element 50. In one non-limiting embodiment, the fluid supply line 84 splits or branches into an engine supply line 88 to convey fluid to the engine block 82 and a filter supply line 90 to convey fluid to the filter element 50. Furthermore, the fluid may be transported from the reservoir 80 to the engine 22 and the filter element 50 by the pump 86.
[0032] The next step 102 in method 94 may provide that fluid transported to the modified valve cover 38 is filtered and/or cleaned by the filter element 50. Subsequently, once contaminants and particles are removed by the filter element 50 the fluid may be directed through the base support opening 48 and enter the channel 60 located within the interior space 58 of the modified valve cover 38. Moreover, according to the final step 104, the filtered fluid may continue to move through the channel 60 and exit through the clean fluid opening 64 located along a planar surface 66 of the modified valve cover 38. Furthermore, as the filtered fluid exits through the clean fluid opening 64 it may be funneled into the drain tube 72 that is attached to the flange 68 located on the planar surface 66 of the modified valve cover 38. In some embodiments, the drain tube 72 may be coupled with the fluid return line 92 and the clean fluid may be transported through the fluid return line 92 back to the reservoir 80. Upon return, the clean fluid may mix with the other fluid present the reservoir 80. In an exemplary embodiment of method 94, the fluid will be continuously circulated by the pump 86 and transported either to the engine block 82 to lubricate and or/cool engine components or transported to the filter element 50 to undergo filtration and/or cleaning.
[0033] It will be appreciated that the use of a valve cover with integrated filter base provides more efficient use of available space within the engine compartment of machines having a combustion engine or comparable power source. Furthermore, the addition of a by-pass or full-flow engine fluid filtering system may be necessary to adhere with certain regulatory requirements and/or user demands seeking a longer lifetime of certain engine fluids. For example, engine oil is one fluid that may have a shortened lifetime due to the accumulation of contaminants during normal use. As a result, to keep the engine and machine working properly, the fluid needs to be changed according to a certain schedule. More specifically, in machines that use diesel engines environmental conditions, as well as, soot, ash or other by-products from the combustion process may contaminate the oil over time and require the oil to be replaced. However, it is costly and often times difficult to change out the contaminated oil because of the equipment size, remote location of equipment use and loss of productivity due to down time. Furthermore, industrial regulations may push for more efficient equipment operation and a reduction of waste or contaminants produced. As a result, improved filtration of engine fluids is necessary in order to increase the intervals between engine fluid changes, increase engine efficiency and to adhere to certain regulation standards.
[0034] The present disclosure achieves the forgoing. More specifically, it will be appreciated that engine fluid filters of the present disclosure are configured to fit within the space provided by the engine compartment. Furthermore, the present disclosure provides easy access to the filter elements needing to be replaced, cleaned or repaired as part of the equipment maintenance schedule.
[0035] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed valve cover with integrated filter base. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed method and apparatus. It is intended that the specification and examples be considered as exemplary only, with a true scope being indicated by the following claims and their equivalents.
