Abstract:
A filter element includes a first, outer tubular construction of filter media defining a first open filter interior; a second, inner tuber construction of filter media defining a second open filter interior; the second construction of filter media being located within the first open filter interior and being radially spaced from the first construction of filter media; and the second open filter interior defines an unfiltered fluid channel. A plastic inner liner is within the first open filter interior to support the first construction of filter media. A plastic outer liner is within the first open filter interior to support the second construction of filter media. A filtered fluid channel is defined between the inner liner and the outer liner. A brace arrangement is between the first and second tubular constructions. The brace arrangement can include a spring, a plurality of gussets, or a solid spacer.

The stabilizing arrangement may include a plurality of projections, each projection extending through an opening in the support and into an open end of a pleat. Methods for stabilizing pleat legs may comprise inserting a projection of a stabilizing arrangement through an opening in a support and into an open end of a pleat.
Abstract:
A filter element is removably positionable within a filter housing that includes a standpipe extending therewithin and provided with a flow control valve. The filter element comprises a tubular filter media, a first end cap, a second end cap longitudinally spaced from the first end cap, and a center tube extending between the first and second end caps. The center tube has a substantially cylindrical body extending between opposite first and second ends of the center tube. The center tube has at least one inlet opening formed on the cylindrical body and a standpipe opening at the second end thereof adjacent to the second end cap through which the standpipe may be inserted longitudinally into the center tube. The center tube further has at least one actuator key provided to open the flow control valve of the standpipe.
Abstract:
A filter element is removably positionable within a filter housing defining a filter chamber for said filter element. The filter housing comprises a standpipe extending within the filter chamber. The filter element includes a tubular filter media circumscribing the standpipe, a first end cap supporting the filter media at one end thereof, a second end cap longitudinally spaced from the first end cap and supporting the filter media at the opposite end thereof, and a center tube extending between the first and second end caps. The center tube has at least one inlet opening therethrough, a bypass opening at a first end thereof adjacent to the first end cap and a standpipe opening at a second end thereof adjacent to the second end cap and through which the standpipe is adapted to be inserted longitudinally into the center tube.
Abstract:
The invention relates to a filter device with a housing (10) composed of at least two housing parts (12, 14) which are to be connected detachably to one another, said housing holding a filter element (26) which comprises a support tube (28) and a filter material (32) surrounding the support tube (28), wherein the ends (34, 36; 38, 40) of the support tube (28) and filter material (32) run into at least one holding part (42, 46; 44, 48). Since, according to the characterizing part of claim 1, the filter material (32) can be withdrawn in a direction (50) to separate it from the support tube (28) and since, in this direction (50) of withdrawal, the support tube (28) and the filter material (32) alike are provided with a predeterminable taper, it is possible for the contaminated filter material (32) to be readily withdrawn from the support tube (28) such that the support tube (28), together with its holding parts, can be reused in conjunction with a newly inserted filter material (32).
Abstract:
A filter element and assembly which has three flow paths, has particular application to a fuel supply system for a diesel engine for filtering flow from the fuel tank as well as fuel returning from the engine that is to be recirculated back to the engine. The filter element and assembly provide a third flow path for also providing for venting of both fuel paths to a drain flow path internally of the filter element.
Abstract:
A multi-layer filter including a first media layer surrounded by a second media layer, a third media layer surrounding the second media layer, and at least one retainer disposed between the first and second media layers or between the second and third media layers. The first, second and third media layers surround the central axis of the filter. The filter has multiple media layers in a compact package, providing increased media surface area which allows greater contaminant holding capacity, lower pressure drop, and lower face velocity.
Abstract:
A sub-component of a replaceable filter element that is interfacably sealing a standpipe includes an end cap, said second end cap defining a first central opening; a central tube extending from the first central opening of the second end cap, wherein the central tube defines an inner surface, an outer surface and a top surface, wherein the top surface defines a second central opening, wherein the central tube includes an actuator excluding keys, free ends, or projections; and a standpipe seal disposed proximate the top surface of the central tube, wherein the standpipe seal defines a third central opening.
Abstract:
A filter assembly for use in filtering stormwater includes a bottom including a boss that includes a rib extending laterally along an inner surface of the boss. The rib includes a locking portion that mates with a corresponding locking portion on a peripheral surface of a connection to an outlet conduit for securing the bottom to the connection thereby inhibiting rotation of the bottom relative to the outlet conduit. A center tube is secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube. The center tube is in communication with an opening in the bottom and a hood is secured to the center tube. A filter medium is located between the hood and the center tube.
Abstract:
A fluid conduit with layered and partial covering material thereon. The fluid conduit may be of many forms and types and attached thereto and configured thereon covering material, in partial form and a selected number of layers. The covering of fluid conduit/conductors resulting in the creation of a novel and very effective, in functionality, of a fluid conduit/conductive system, such as a septic pipe of smooth wall, of corrugated form, of any form of cross sectional configuration including circular, elliptical, rectangular, triangular or any other geometric shape any of which will and can provide for the flow of a fluid of forms such as septic flow fluid and the like. Included herein as a part of the invention is fluid conduits produced by the means and methods of this invention. Substantially, the fluid conduit system having incorporated therein and thereon the form and layers of covering created as a consequence of the means and method of configuring such conduit included as a feature of the invention. Used herein is a multilayer fabric of varying deniers for the processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused and/or returned to the earth and particularly to the water table. More particularly the multilayer fabric, each layer being of selected denier, is used in combination with conduit in a drainage field or leaching system usually associated with a septic tank or septic system. Most particularly the multilayer fabric of varying deniers is wrapped around corrugated plastic pipe of the type well known in the field of drainage or leaching fields. At least one of the multilayer fabric layers is formed from an unstructured assemblage of fibers. The unstructured assemblage of fibers are supported by an outer sheeting however it could be made of a grid mesh or additional material choices which in effect will provide for separation between layers. The unstructured assemblage of fibers provides a large surface area whereon consequent biodegradation of the oils, greases and chemicals takes place permitting treated fluid to pass omnidirectionally through the unstructured assemblage of fibers and subsequently leach into the ground. The system generates bacteria more quickly and thereby causing the system performance to be enhanced in quality of performance and in the speed of performance—speed of performance was increased over prior art methods by a substantial of amount.
