摘要： A closed crankcase ventilation system which relies on a vacuum assist from the turbocharger inlet to suction blow-by gases from the crankcase. The system includes a coalescer/filter which is operative to filter any oil particles which may be entrained in the blow-by gases before they are released into the turbocharger inlet. A pop off valve is also included in order to prevent the engine crankcase from becoming over pressurized as a result of back pressure caused by either a plugged coalescer/filter or some catastrophic engine malfunction. Further included is a vacuum limiting valve which prohibits the vacuum assist produced by the air inlet to the turbocharger from producing too low of an absolute pressure, thereby preventing an imbalance in pressure across the seals of the turbocharger. The system further includes a bypass valve which also prevents the crankcase from becoming over pressurized by routing the flow of blow-by gases around the coalescer/filter if the pressure in the crankcase becomes too great. Finally, the present invention incorporates a single mounting head which allows the various valves and filters of the present invention to be mounted thereon. The mounting head may then be conveniently attached to the engine at a single location.
摘要翻译：闭合的曲轴箱通风系统，其依赖于来自涡轮增压器入口的真空辅助以从曲轴箱吸入窜气。该系统包括聚结器/过滤器，其可操作以过滤在窜气被释放到涡轮增压器入口之前可夹带在窜气中的任何油颗粒。还包括一个截流阀，以防止发动机曲轴箱由于堵塞的聚结器/过滤器或一些灾难性的发动机故障引起的背压而变得过压。进一步包括一个真空限制阀，其禁止由涡轮增压器的进气口产生的真空辅助产生太低的绝对压力，从而防止涡轮增压器的密封件两端的压力不平衡。该系统还包括旁通阀，如果曲轴箱中的压力变得太大，也可以通过绕过聚结器/过滤器周围的窜气的流动来防止曲轴箱过度加压。最后，本发明包括一个单独的安装头，其允许本发明的各种阀和过滤器安装在其上。然后，安装头可以在单个位置方便地附接到发动机。

摘要： A snap-together, all-plastic filter assembly for filtering fluids includes a generally cylindrical injection molded plastic outer shell which has a closed base and an open opposite end and which defines a hollow interior which receives a filtering element and an integral injection molded plastic endplate/centertube member. The outer shell is injection molded with a pair of concentric, generally cylindrical, inner annular walls which are integral with the closed based and extend part way toward the open end of the outer shell. The filtering element which has a hollow interior fits down within the outermost of the two concentric annular walls and the centertube of the endplate/centertube member extends through the center of the filtering element and snaps in place by means of snap-fit projections which snap into snap-fit pockets disposed within the inner most of the two concentric annular walls. The filter assembly is designed as a spin-on filter and is threadedly engaged and positioned onto a mounting base thereby completing the fluid flow path. In related embodiments the filtering element is preassembled to the endplate/centertube member as a replaceable cartridge.

摘要： An all-plastic filter assembly for filtering fluids includes a generally cylindrical injection molded plastic outer shell which has a closed base and an open opposite end and which defines a hollow interior which receives a modular filler cartridge. The outer shell is injection molded with a generally cylindrical mounting stem which is integral with the closed base and extends part way toward the open end of the outer shell. The filter cartridge includes a generally cylindrical filter element and a molded endplate and centertube member bonded to the filter element. The centertube portion of the molded member is received by the mounting stem as part of the positioning and mounting of the filter cartridge into the outer shell.

摘要： This disclosure illustrates a replaceable filter assembly for fluids in which the filter has a shell formed from an injection molded threaded end and an integral blow molded closed end to form a unitary shell. A seal such as a flange is provided adjacent to the threaded end so that a pressure seal can be maintained. A filter medium is supported within the shell so as to direct fluid flow through it to remove contaminants. The shell can be formed from plastic materials such as polyester terephthalate (PET), polyether sulfone (PES), and polyether urethane (PEU). This construction enables an inexpensive filter assembly and, with transparent plastic materials, an indication of the contaminant removal activity within the filter.
