    Abstract: A piston pressurized water filter activated by the user or external source. The water filter assembly includes a hollow cylindrical water reservoir, a hollow cylindrical piston threaded into the top of the water reservoir, and a water filter threaded into the bottom of the water reservoir. The interior of the water reservoir is sealed by the piston and water filter. When the water reservoir is filled with unfiltered water, the piston can be threaded down into the water reservoir to create sufficient pressure on the unfiltered water and force the water into the water filter. The water filter can include any combination of carbon, ceramic or other filtering material in a block or disk form. Water is forced into the water filter, through the carbon or ceramic filter mass, and into a container that may or may not be coupled to the water filter.

    Abstract: A filter cartridge with a filter element inserted in a receiving space formed by a central cylindrical flow pipe 32 and a peripheral wall 34 is in terms of its possibilities of use and possibilities of adaptation to filtration problems substantially improved in that the filter element consists of fleece-like filter material and in that in its radial direction it comprises mutually enclosing zones of different filtering properties. For practical purposes, these zones can follow one another without any transition or they may be constructed with filtering properties which are varied in stepwise fashion. The filter element can be formed by the combination of a pleated filter fleece with a rolled-up filter fleece, the pleated part of the filter element being optionally on the inside or the outside. A rolled-up filter element or the rolled-up part of a filter element may be produced from a strip of fleece-like filter material, the said strip possibly having filtering properties which over its length are varied continuously or from portion to portion.

    Abstract: Filter pads, which are made inherently stable by binders and by removal of the binders can be converted in packings to be maintained under substantially constant surface pressure between rigid filter brackets, are produced first as molded bodies from a suspension of filter aids in liquid by depositing granular, fibrous, or fiber-containing filter aids or mixtures of those filter aids in a casting mold, there being used high rates of flow while avoiding turbulences, and adding binders to the suspension so that the molded body can be stabilized by activation of the binder while drying. It is possible in this process also to manufacture multi-layered filter pads, it having been surprisingly found in those multi-layered filter pads that the layer assembly is kept intact during the filtration even in the filter packing that no longer contains binders. The filter pads or the filter packings produced therefrom according to the invention can, when used, and after reflushing and regeneration operations, finally be utilized, after being replaced, as filter aids in the deposit filtration process.

    Abstract: A filter element adapted to be sealingly clamped in a filter housing. The element comprises a porous hollow cylindrical integral self-supporting bonded fibrous structure. The structure has thermally melt bonded to at least one end thereof, a thermoplastic polymer closed cell foam sealing gasket. The gasket is adapted to provide a sealing surface between the end of the cartridge and the sealing edge of the filter housing. In a preferred embodiment, the sealing edges of the filter housing used in conjunction with the aforedescribed filter element comprises at least two circular sealing edges concentric to the axis of the cylindrical filter element. Such a combination provides a means for determinging whether there is leakage past the sealing edges by the discoloration of the sealing gasket area between the concentric sealing edges by the liquid being filtered.

    Abstract: An improved return line filter is provided for use with a fluid system having a fluid reservoir which is at least partly filled with a fluid. The return line filter comprises an elongated housing having an open top and a partially open bottom and in which the housing is positioned within the reservoir so that the lower end of the housing is submerged in the reservoir fluid. A fluid inlet is formed on the lower end of the housing. A filter assembly is provided for use with the housing and comprises a tubular filter element open at each end and a holder assembly which is detachably secured to one axial end of the filter element. The entire filter assembly is insertable through the open top of the housing so that the tubular filter element is positioned coaxially around and spaced radially outwardly from a portion extending upwardly from the housing thus forming an annular chamber therebetween. Fluid seals sealingly connect both axial ends of the filter element with the housing portion while a fluid passageway fluidly connects the housing inlet with the annular inlet chamber. In addition, a deflection and antifoam tube secured to the holder assembly is positioned coaxially around and spaced radially outwardly from the filter element so that fluid flow from the filter element is deflected downwardly toward the partially open bottom of the housing. This construction for the filter assembly creates a reverse fluid flow in which the fluid must first flow upwardly from the bottom of the housing, out through the filter element and subsequently down through the lower open end of the housing.

    Abstract translation: 提供改进的返回管线过滤器用于具有至少部分地填充有流体的流体储存器的流体系统。 返回线过滤器包括具有开口顶部和部分开放底部的细长壳体，并且壳体定位在储存器内，使得壳体的下端浸没在储存器流体中。 流体入口形成在壳体的下端。 提供了一种与壳体一起使用的过滤器组件，并且包括在每个端部处开口的管状过滤器元件和可拆卸地固定到过滤元件的一个轴向端部的保持器组件。 整个过滤器组件可以通过壳体的开口顶部插入，使得管状过滤器元件同轴地设置在从壳体向上延伸的部分周围并径向向外间隔开，从而在它们之间形成环形室。 流体密封件将过滤元件的两个轴向端部与壳体部分密封地连接，而流体通道将壳体入口与环形入口室流体连接。 此外，固定到保持器组件的偏转和消泡管被同轴地设置在过滤器元件的周围并且与过滤器元件径向向外间隔开，使得来自过滤元件的流体流向下偏转到壳体的部分敞开的底部。 用于过滤器组件的这种结构产生反向流体流，其中流体必须首先从壳体的底部向上流出，穿过过滤器元件，然后向下穿过壳体的下开口端。
