A device for supplying injection water capable of stably supplying the water to a water injection system of a vehicle. The device for supplying injection water includes a storage unit configured to store water, a management unit mounted on the storage unit and configured to detect a state of the water stored in the storage unit and manage the water, a transport unit connected to the storage unit through the management unit and configured to outwardly move the water, and an integrated controller configured to control operations of the management unit and the storage unit.

A device is provided that provides an unbiased filtration effect and an effect of removing captured substances through backwashing by causing a fluid to uniformly pass through a filter element over the entire length in an axial direction at the time of backwashing so as to efficiently rotate a captured-substance removal tool in a filtration unit 1 which includes the captured-substance removal tool 20 axially supported inside the tubular filter element 2 to be rotatable.

A filter system may include a housing, a filter element, and a separate positioning mechanism. The housing may include an opening, a function carrier, a drain opening, and a radially protruding contour. The filter element may include a first end disc, a second end disk, and a filter material disposed between the first end disk and the second end disk. The first end disk may include at least one of a radially projecting contour and an inwardly projecting recess. The second end disk may include a central opening and an eccentrically projecting locking pin. The central opening may be adapted to interact with the function carrier. The positioning mechanism may have a body with a first recess and at least one second recess, which may be configured to facilitate positioning and aligning the filter element in the housing such that the locking pin engages in the drain opening.

A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

A removable filter cartridge includes a filter housing containing a filter and a sealing valve coupled to an open end of the filter housing. The sealing valve configured to removably couple the removable filter cartridge to a filter head. An open position allows fluid to flow into and out of the internal volume of the filter housing. A closed position seals the filter housing. A method for retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.

A microorganism sampling device includes: a head part that has a water supply channel to which a water supply pipe for supplying sample water can be connected; a housing part to an upper part of which the head part can be detachably attached; a frame-structured tube; a tubular filter that is arranged within the tubular body; a cup that communicates with the tubular filter and is attached to one end of the tube body; and a cap that has a channel communicating with the tubular filter and is attached to the other end of the tube body. The microorganism sampling device further includes a filter part housed in the housing part, in which a bottom part of the cup is supported by a bottom part of the housing part. The head part is attached to an upper part of the housing part.

An oil filter for a motor vehicle has a filter cartridge which is disposed in an oil filter housing of the oil filter. The filter cartridge has a channel for filtered oil which is surrounded at least regionally by a filter material in the radial direction. At least one through opening is formed in a wall of the channel. An emergence of filtered oil via the at least one through opening into a channel for the filtered oil provided on sides of the oil filter housing is preventable by bringing the filter cartridge into a first position. An inlet into the channel provided on sides of the oil filter housing fluidically connectable to the at least one through opening by bringing the filter cartridge into a second position in which the filter cartridge is shifted relative to the first position in an axial direction.

A blood component collection cassette that can trap a substance where blood components coagulate by using a simple and economical configuration, and a manufacturing method of the blood component collection cassette are provided. A blood component collection cassette (28) includes a cassette main body (40) where a flow path (42) is formed and is configured to be mountable to a centrifugal separation device (14). The cassette main body (40) has a first sheet (40a) and a second sheet (40b) which are formed of a soft material. The flow path (42) is formed between the first sheet (40a) and the second sheet (40b). A filter member (60) for trapping a substance where blood components coagulate is arranged on the flow path (42) in the cassette main body (40).
