The present invention provides a depth filter which contains fine particles and coarse particles, and which exhibits excellent filtration precision with respect to a high concentration fluid and/or a high viscosity fluid. This depth filter enables filtration for a long period of time, while maintaining a low filtration pressure.

The present invention is a depth filter which is obtained by winding a fiber sheet into a cylinder, and which comprises a pre-filtration layer and a microfiltration layer; the pre-filtration layer and the microfiltration layer are formed of a fiber sheet; the fiber sheet is composed of a nonwoven fabric or a web; the average fiber diameter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer; and the average weight per square meter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer.

The present invention provides a multi-structure filtration device for filtering, separating, and dehydrating foreign substances in water, the multi-structure filtration device comprising: a filtration tank filled with filtration target fluid inside; a filtration device unit having a cylindrical double drum structure, installed in the filtration tank so that a part of the filtration device unit is submerged in the filtration target fluid, and including two or more filters having different mesh sizes that are respectively wound on an inside and an outside of the filtration device unit, and one or more washing modules washing foreign substances attached to the filter wound on an outside of the filtration device unit. Accordingly, the multi-structure filtration device can have excellent filtration performance by double-filtering the target fluid using two or more filters, can operate in an eco-friendly manner by recycling filtered water and effectively washing the filters using the filtered water without separate chemicals, can increase the durability of the filters, and can reduce the washing and processing cost by reusing the filters.

The invention relates to a system for engine oil storage and filtration in an internal combustion engine, comprising at least one oil storage device as part of an engine oil circuit, at least one filtration device, and at least one oil delivery pump, wherein the system is characterized in that the filtration device is connected upstream of the oil delivery pump in relation to the delivery direction of the oil, with only suction filtration being provided.

An apparatus for a switchable filter assembly includes a first conduit coupled to a second and a third conduit, where a liquid has the ability to flow through the first conduit to the second conduit and the third conduit, and where the second conduit and the third conduit are arranged in parallel. A first assembly is capable of sliding inside the first conduit, such that a position of the first assembly determines an amount of liquid flowing to the third conduit. The first assembly includes a compressible member coupled to a first structure, where the first structure prevents the liquid from passing through the first conduit to the third conduit. An amount of compression of the compressible member coupled to the first structure is dependent on a pressure of the liquid flowing from the first conduit to the second conduit.

The invention relates to an engine oil system (1, 1′, 101) for supplying oil to oil using components (3) in a vehicle (800). The engine oil system comprises an oil pan (10) for holding oil received from the oil using components, an oil pump (20) fluidly connected to the oil pan for pumping oil from the oil pan to the oil using components, and an oil filter (30, 30′ 130) configured for cleaning the oil. The oil filter has a filter inlet (32, 32′, 132) for receiving oil to be cleaned, and a filter outlet (34, 34′ 134) for discharging oil from the oil filter. The oil filter is arranged in the oil pan such that, in use, the filter outlet discharges oil into the oil pan.

A coalescing filter element provides an integrated filter element with a three stage design with a hydrophobic or hydrophilic coalescing layer. A coalescing filter element comprises: a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; and e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer. The coalescing layer may be a hydrophobic or a hydrophilic coalescing layer. A filter assembly will include the coalescing filter element of the present invention.

A suction filter for an automatic transmission utilizes two different types of filter media: a coarse filter media and a fine filter media. The two types of media are arranged in series within a housing such that fluid flows through only one of the two filter media. A hinge valve is arranged in series with the coarse media. The hinge valve passively opens in response to a pressure differential. The hinge valve defines a non-zero flow area when in the closed position and an increasing flow area as it opens. The flow restriction associated with the hinge valve permits a larger ratio of coarse media area to fine media, thereby decreasing the flow restriction when the oil is cold without decreasing the clean-up rate in normal operating conditions.

Provided is a multi-layered filter for separating blood components and a disease diagnosis kit using the same. The multi-layered filter for separating blood components may include a first filter unit configured to separate blood cells from a whole blood sample, a second filter unit configured to separate cell fragments having blood platelet or exosome, and a third filter unit configured to separate protein, wherein the whole blood sample is separated into blood components by passing through the filter units provided to have different pore sizes, thereby effectively separating individual components of the blood without a separate machine. In addition, after filtering, the multi-layered filter may be disassembled to diagnose each component remaining in the filter so as to be utilized for diagnosis.

A filter element for a filter unit for filtering a fluid may include a filter element body. The filter element body may include at least one structural body and a support body.
