A plug for retaining a filter screen in a fluid port of a servovalve, the plug comprises an annular body. The annular body comprises opposed first and second axial annular end surfaces. A radially inner surface extends between the first and second axial annular end surfaces and a radially outer surface extends between the first and second axial annular end surfaces. At least one recess is formed in the radially inner surface for receiving a tool for removing the plug from the port. A plurality of slots is formed in the first axial annular end surface and extends into the at least one recess for providing access for the tool to the at least one recess.

A filter that includes: a filter base portion having a first main surface and a second main surface, the filter base portion defining a plurality of through-holes connecting the first main surface and the second main surface via an inner wall extending from the second main surface toward the first main surface; and a support portion that has a plurality of protruding portions located in respective through-holes of the plurality of through-holes and disposed on the second main surface of the filter base portion, the plurality of protruding portions having an outer wall in contact with the inner wall of the filter base portion, wherein a first opening on the first main surface side of the filter base portion is larger than a second opening on the second main surface side of the filter base portion, and there is a clearance between the filter base portion and the support portion.

Systems and methods are disclosed that include providing a filter assembly having a filter body with an inlet and an outlet, a filter membrane support disposed within the filter body between the inlet and outlet, a filter membrane coupled to the filter membrane support, and at least one component that passes through the inlet, the filter membrane support, and the outlet to carry an electrical current, a fluid, or combinations thereof through the filter.

The present invention relates to a filter laminating structure for an intravenous infusion filter that is capable of allowing a filter body to be supported against a filter type of support body, thereby preventing the filter body from being broken or damaged even by the injection of medicine under high pressure, and the filter laminating structure including an upper filter housing having a medicine injection hole adapted to inject medicine therethrough, a lower filter housing coupled to the underside of the upper filter housing, a filter body located at an upstream side in the flow of the medicine injected into the medicine injection hole to perform a filtering function for the medicine, and a support body located at a downstream side in the flow of the medicine on the underside of the filter body to support the filter body thereagainst.

A pod assembly for use in a beverage machine is provided. The pod assembly includes a container and a filter disc that is detachably coupled to the container. The container includes a base, a side wall having a lower rim coupling the side wall to an outer perimeter of the base, and a flange coupled to an upper rim of the side wall and extending radially outward from the upper rim. The filter disc includes a central portion with multiple central openings, a dome-shaped portion with multiple secondary openings, an annular portion extending radially outward from the dome-shaped portion, a foot portion extending vertically from the annular portion in a first direction, and a retention flange extending vertically from the annular portion in a second direction.

A laundry appliance includes a cabinet, a tub, and a pump for recirculating wash fluid from the tub to a filter container. The filter container includes a fluid inlet in fluid communication with the pump and fluid outlet in fluid communication with the tub. The filter container also includes a filter housing for directing wash fluid from the fluid inlet to the fluid outlet. A self-clearing filter assembly is provided within the filter housing. The self-clearing filter includes side walls and a filter base having at least one inclined surface. The self-clearing filter is situated such that the inclined surface is below the fluid inlet. The self-clearing filter prevents microfibers and other debris from passing through to the outlet of the filter container. Simultaneously, the force of the wash fluid on the inclined surface forces the microfibers and other debris to a trough, where it can be collected and disposed of.
