    Abstract: A transmission fluid filter assembly includes a filter media, a fluid discharge conduit associated with the filter media, a magnetic particle trap, and a connector arranged to lie under the filter media and the magnetic particle trap. The connector is adapted to be coupled to a filter mount provided at an opening in a transmission pan to support the filter media, fluid discharge conduit, and magnetic particle trap in an interior region of a transmission pan containing transmission fluid to be filtered. The magnetic particle trap attracts and retains particles of ferrous material to minimize discharge of such particles from the transmission pan through the fluid discharge conduit.

    Abstract: A filter has a filter housing. An adjustable support couples a filter element to the filter housing. A first end of the adjustable support is fixedly connected to the housing. A movable portion of said adjustable support is coupled to said filter element. The movable portion is opposite the first end. The movable portion is disposed in the throat of the filter element. The filter element occupies a fluid intake position when said movable portion is in a first position. The filter element occupies a bypass position when said movable portion is in a second position.

    Abstract: A system for filtering fluids uses the pressure differential across a filter element between an internal filter volume and an external filter volume to control the rate of fluid flow through the filter element. The internal filter volume communicates with a backwash volume contained in the external filter volume. The backwash volume may be movable relative to the filter element to clean accumulated filtrate from the filter element through backwashing. By increasing the pressure in the internal filter volume, the rate of backwashing can be increased while the rate of fluid flow into the internal filter volume is decreased. Particularly when the filter element becomes clogged, damage to a filter caused by an excessive pressure differential across the filter element may be decreased.

    Abstract translation: 用于过滤流体的系统使用内部过滤器体积和外部过滤器体积之间的过滤器元件上的压力差来控制流过过滤元件的流体流速。 内部过滤器体积与包含在外部过滤器体积中的反洗液体积进行通信。 反洗容积可以相对于过滤元件移动，以通过反向洗涤从过滤元件清洗累积的滤液。 通过增加内部过滤器体积中的压力，可以提高反冲洗速率，同时流入内部过滤器体积的流体速率降低。 特别是当过滤元件堵塞时，由过滤元件过大的压差引起的过滤器损坏可能会降低。

    Abstract: A coreless filter element for a filter housing includes cylindrical filter media having longitudinally-extending pleats extending from one end cap on the filter media to another end cap on the filter media. The filter media is preferably a multi-layered structure with an outer support mesh layer attached to an inner prefiltration layer by an intermediate adhesive web layer. An inner wrap of a porous fibrous filter media is provided within the central cylindrical cavity of the pleated filter media. The wrap has a cylindrical form with an outer surface which is joined to the inner pleat peaks of the media such as with one or more beads of adhesive, or with a continuous adhesive layer applied to the outer surface of the support wrap. The filter element with inner support wrap can be easily located over a metal support core integral with the filter housing, and provides structural integrity for the pleats of the filter media. According to another embodiment, a series of circumferential bands formed from porous or imperforate material can be provided within the central cylindrical cavity and adhesively joined to the inner pleat peaks of the filter media. In either embodiment, the inner support wrap or bands provide structural integrity for the pleats, provides a filter element which is easily manufactured, and which allows the filter element to be easily located over the support core in the filter housing, and removed therefrom when the filter element becomes spent. The coreless filter element is also preferably formed from components which can be easily incinerated or disposed of in a landfill.

    Abstract: A storm drain filter is sized to cover the opening of a storm drain. It includes a top debris tray removably positioned within a bottom media tray. Each tray includes a peripheral trough surrounding a central overflow opening. The top tray is shorter in height than the bottom tray, so that a filter media receiving chamber is defined between the top tray and the bottom tray. Filter media is positioned in the filter media receiving chamber. A handle is attached across the central overflow opening of the top tray. In a first embodiment, the bottom surfaces of the top and bottom trays are perforated. In a second embodiment, the inner walls of the top and bottom trays are perforated. In either embodiment, water flowing into the filter is distributed around the top trough, passed through the perforated surface of the top tray, the filter media, the perforated surface of the bottom tray, and into the storm drain. Hydrocarbons and other contaminants are filtered by the filter media. Large particles and debris are collected in the trough of the top tray. The filter may be easily cleaned by lifting out the top tray, shaking out the debris, and replacing it in the bottom tray. The removable top tray also enables easy inspection or replacement of the filter media.

    Abstract: A filter of the type used to filter gases or liquids has molded plastic end caps on each end of the filter element with the ends of the filter element molded into the end caps. To prevent the end of the filter element from being exposed through the exterior surface of one of the end caps, a spacer is located between the end of the filter element and the exterior surface of the end cap. The spacer allows the plastic material of the end cap to permeate the spacer to form a thin layer of plastic on the end of the filter element. This prevents thin spots in the end cap which could result in leakage through the end cap.
