摘要： Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.

摘要： Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral "V" shapes).

摘要： Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a pumping pressure created by the porous media of the rotating coalescer to maintain positive recirculation of filtered blowby gases through a potential leak gap between a static housing inlet and a spinning component of the rotating coalescer. In some arrangements, the porous media is fibrous media. The filter media may be pleated or non-pleated. The positive recirculation caused by the pressure balance prevents unfiltered blowby gases from bypassing the media of the rotating coalescer from the upstream side to the downstream side of the filter media through the gap. During operation, the pressure balance between the upstream side and downstream side of the filter media maintains the positive recirculation, which in turn maintains a high filtration efficiency.
摘要翻译：描述了旋转聚结器曲轴箱通风（CV）系统。所描述的CV系统利用由旋转聚结器的多孔介质产生的泵送压力，以保持过滤的窜气气体通过静态壳体入口与旋转聚结器的旋转部件之间的潜在泄漏间隙的正向再循环。在一些布置中，多孔介质是纤维介质。过滤介质可以是打褶的或不打褶的。由压力平衡引起的正循环可以防止未过滤的窜气通过间隙从过滤介质的上游侧到下游侧绕过旋转聚结器的介质。在操作过程中，过滤介质的上游侧和下游侧之间的压力平衡维持正的再循环，从而保持较高的过滤效率。

摘要： A filter cartridge having a bypass filtration media is described. The filter cartridge includes main filtration media. In some arrangements, the main filtration media includes first filtration media and second filtration media that has a different filtering efficiency than the first filtration media. The filter cartridge is configured to be installed in a filtration system having a bypass mode. While in the bypass mode, fluid passing through the filtration system is allowed to bypass the main filtration media. To avoid unfiltered fluid from passing from the inlet of filtration system to the outlet (e.g., and on to an internal combustion engine), the fluid flows through the bypass filtration media (e.g., during cold start conditions). In some arrangements, the bypass filtration media has a lower filtering efficiency than the main filtration media.
摘要翻译：描述了具有旁路过滤介质的滤筒。滤芯包括主过滤介质。在一些布置中，主要的过滤介质包括具有与第一过滤介质不同的过滤效率的第一过滤介质和第二过滤介质。滤筒被配置为安装在具有旁路模式的过滤系统中。在旁路模式下，允许通过过滤系统的流体绕过主过滤介质。为了避免未过滤的流体从过滤系统的入口通过出口（例如和内燃机），流体流过旁路过滤介质（例如，在冷启动条件下）。在一些布置中，旁路过滤介质具有比主过滤介质更低的过滤效率。

摘要： Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The filter media is HSRC filter media. As such, the filter media has a higher resistance to compressibility than traditional coalescer filter media, such as filter media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

摘要： Fuel filtration systems having an automatic drain assembly for water that accumulates in the filter housing are described. The filtration system includes a filter media that is configured to remove particulate matter and dispersed water contained within the fuel. The water is drained to a drain reservoir within the filter housing where the water collects. When the water reaches a threshold level, a controller initiates a warning to the engine operator, such as a dashboard light, that instructs the operator to shut the engine off. When the engine is shut off, the collected water is drained through a valve of the automatic drain assembly. In some arrangements, the automatic drain assembly can be retrofitted to existing fuel filtration systems thereby reducing the cost of fitting the automatic drain assembly to existing internal combustion engines.
