摘要： A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

摘要： A filter element has a pleated filter mat (3). The terminal axial ends (7, 8) of the mat are connected to end caps (9, 11). The mat has a main structural layer (15) having filtering properties and a first additional structural layer and a second additional structural layer (17,19). The surface area of each of the additional structural layers (17, 19) is smaller than the surface area of the main structural layer (15). The axial ends (12, 14) of one additional structural layer (17) is located at an axial distance from the axial ends (16, 18) of the other additional structural layer (19) on the filter mat (3).

摘要： A replaceable subsea filter uses a hot-stab style connection. The filter has a flow path located along a central axis. At a distal end of the of the filter, the flow path locates inside a subsea receptable, typically associated with a reservoir or sea chest for a hydraulic actuator. At a proximal end, the flow path opens into an annulus around the stab-connecter, the annulus being separated from the surrounding waters by annular filters.

摘要： A filter assembly has a housing defining an inlet and an outlet. A plurality of chemical filter elements are disposed in the housing and are arranged in a series with respect to fluid flow. A spacing region is between adjacent filter elements in the series. Also disclosed is an assembly having a housing and a first and second chemical filter element. The second chemical filter element is downstream of the first chemical filter element. Each chemical filter element has a sheet of chemical filter material having a first edge and a second edge. A first flow path is defined parallel to a surface of the first sheet extending from its first edge to its second edge. A second flow path is defined parallel to a surface of the second sheet extending from its first edge to its second edge.

摘要： A filter device for transmission oil has a filter element (24) insertable into a transmission oil pan (70) with a filter medium (32) separating an unfiltered side from a filtrate chamber connected to an outlet (38, 50, 72), to which a suction oil pump can be connected. The filter medium (32) has a first structural layer (46) having a predetermined surface area and predeterminable filter properties and has a second structural layer (44, 60) having predeterminable filter properties. The surface area of the second structural layer (44; 60) is different from the surface area of the first structural layer (46). The structural layers (44, 46, 60) encompass an inner filter cavity (30) and are pleated having the same type of pleats. The pleated structural layers (44, 46, 60) extend in axial alignment between two end caps (22, 34) of the filter element (24). Viewed in the flow direction of the fluid flow to be cleaned, the structural layers (44, 60) having the higher filtration grade are downstream of an upstream structural layer (46) having a lower filtration grade.

摘要： An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.

摘要： 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.
