Provided is a filtration device that can increase a filtration treatment amount by suppressing clogging of a filtration filter. A filtration device according to the present invention includes: a filtration filter that includes a filter that filters a filtration target contained in a fluid, and a frame that holds the filter; a support structure that holds the frame such that the filter is bent; and a fluid supplying unit that supplies the fluid with the filter being in a bent state.

A multi-component end cap is provided. The multiple components combine to form one or more seal carriers where each seal carrier is formed in part by at least two different ones of the components. Methods of manufacturing an end cap having multiple components are also provided.

A filtering device for fluids includes a filter housing (1) and a filter element (9) received in the filter housing. The filter element has an end cap (17) on at least one end. The end cap forms an enclosure for the corresponding end edge of the filtering material (23, 35) and is fixed on an element receiver (13) interacting with the bottom part (5) of the filter housing (1) to fix the position of the filter element (9) in its functional position. The element receiver forms a fluid path for the cleaned fluid exiting the hollow chamber (19) of the filter element (9). The element receiver (13) contains a valve arrangement (55) blocking the fluid path (35). A control device (79, 83) releasing the valve arrangement (55) in the functional position is on the end cap (17) of the filtering element (9). The end cap is fixed on the element receiver (13).

A filter turning mechanism is attached to an engine in proximity to a filter (such as an oil filter), and may be used to install or remove a filter by turning the filter. The filter turning mechanism contacts a filter, and rotates the filter when the filter turning mechanism is rotated with a tool. One implementation of the filter turning mechanism includes an inner drive gear and a filter drive mechanism. The inner drive gear normally spins freely within the filter drive mechanism, but when pushed into the filter drive mechanism with a suitable tool such as a ratchet extension, the inner drive gear engages the filter drive mechanism, thereby causing rotation of the inner drive gear to rotate the filter drive mechanism as well, which in turn rotates the filter.

A fuel filter device for operation in a position under non-extreme conditions, when there is enough time for replacement of the clogged filter element, or in a reverse position in a fuel bypassing state for non-stop operation under extreme conditions, when there is no time for replacement of the clogged filter element. The device consists of cup-shaped members, which are interconnected through a threaded connection and form a cavity that contains a spring compressed between the bottom of an opening of one of the cup-shaped members and an abutment formed between two openings of another cup-shaped member. The compression force of the spring is applied to a seal ring placed into an annular groove formed in the abutment surface through a flange of the filter element. Another improved sealing feature is provided by a second seal ring, which seals the threaded connection, when the connection is tightened.
