A pressure control device includes: a body having a groove-shaped flow path including a groove part and a widened part connected to the groove part and having a width larger than a width of the groove part; and a filter unit accommodated in the widened part to intercept the groove-shaped flow path and capturing foreign matters mixed in a fluid passing through the groove-shaped flow path. The filter unit includes: a filter member in a cylindrical shape whose central axis is along a depth direction of the widened part; and a cap attached to the filter member on one end side in the central axis direction and having a defining part defining a circumferential-direction disposition position of the filter member to the groove part.

A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.

A fuel injector assembly includes a fuel injector and an annular filter coupled with the fuel injector, the annular filter being snap-fitted with one of a nozzle case or an injector body of the fuel injector and slip-fitted with the other of the nozzle case or the injector body. The annular filter has a perforated wall forming a filtration screen covering an actuation fluid inlet formed in the nozzle case and positioned upstream of the actuation fluid inlet to trap particulates in incoming actuation fluid.

A blood filtering device comprises a casing defining a containment volume and provided with at least a first inlet for the venous blood, at least a second inlet for the intracavitary blood, at least a third inlet for the extra cavitary blood and at least an outlet mouth for the blood; blood filtering means which are housed inside the containment volume and delimiting at least one filtering volume communicating with the blood inlets and at least one collecting volume communicating with the outlet mouth; where filtering means comprise: at least a first filtering element defining a closed profile and delimiting a first filtering volume communicating with the first inlet; at least a second filtering element defining a closed profile and delimiting a second filtering volume communicating with the second inlet; at least a third filtering element defining a closed profile and delimiting a third filtering volume communicating with the third inlet.

A method includes providing a computer-readable three-dimensional model of a filter medium including a plurality of segments, each segment of the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter medium, the filter medium including a first end defining a first cavity that extends from the first end along a predetermined direction that defines an undercut along the first predetermined direction; and successively forming each layer of the filter medium by additive manufacturing.

A filter capsule for secondary filtration of extracted coffee is provided, where the filter capsule comprises a housing and at least one filter element or consists thereof. The housing comprises a bottom, at least one side wall and at least one cover or consists thereof, the at least one filter element being disposed in an interior space of the housing. Coffee extracted on a brewing strainer can be subjected to a secondary filtration so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element of the filter capsule and a new type of coffee is produced. The use of the filter capsule for secondary filtration of coffee is therefore proposed.
