    Abstract: An easily removable tubular filter assembly, such as from a cylindrical array of parallel filter tubes arranged between two spaced parallel circular plates, which array is immersible in a liquid to be filtered. Each filter tube comprises a central open-ended perforated rigid tube with flanged tubular bushings for each end, and a fabric tubular sock which surrounds the perforated tube and tucks in the ends of the tube around the outer flanges of said bushings. A flanged tubular ferrule snugly fits in the bushing at one end of the fabric-covered tube to hold the tucked-in sock in place and seal its flange into an aperture in a wall of a suction chamber which may comprise one of the parallel circular plates of the array assembly. The other end of each filter tube is closed by a plug which snugly fits into the other end bushing and holds the other tucked-in end of the sock in place, as well as supports that end of the filter tube in an aperture in the other spaced circular plate, identical with that plate forming the wall of the suction chamber. The outer end of this plug provides a seat for a compression spring which is compressed by a removable plate bolted to the adjacent apertured plate, which compressed spring urges all the filter tubes into sealing contact with the apertures in the suction chamber. Thus, by removing the outer bolted plate, which may cover, preferably not more than half of the apertures and filter tube ends, enables easy axial removal of its associated filter tubes from the array for replacement without further disassembly of the array.

    Abstract translation: 一个易于移除的管状过滤器组件，例如从平行的滤光管的圆柱形阵列排列在两个间隔开的平行圆形板之间，该阵列可浸入待过滤的液体中。 每个过滤管包括一个中心开口的穿孔刚性管，每个端部均带有带凸缘的管状衬套，以及一个围绕多孔管的织物管状袜，围绕着衬套的外凸缘折叠在管的端部。 带凸缘的管状套圈紧密地配合在织物覆盖的管的一端的衬套中，以将折叠的袜子保持在适当位置，并将其凸缘密封到吸入室的壁中的孔中，该吸入室的壁可以包括平行的圆形板 的阵列组件。 每个过滤管的另一端通过紧密地配合到另一端衬套中的塞子封闭，并将袜子的另一个插入端保持在适当位置，并且将过滤管的端部支撑在另一端的孔中 与形成抽吸室壁的板相同。 该插头的外端为压缩弹簧提供座位，压缩弹簧由可螺栓连接到邻近的多孔板上的可移动板压缩，该压缩弹簧促使所有过滤管与抽吸室中的孔密封接触。 因此，通过移除可以覆盖，优选地不超过孔和过滤管端部的一半的外部螺栓固定板，能够容易地从阵列轴向移除其相关联的过滤管用于替换，而无需进一步拆卸阵列。

    Abstract: The invention relates to a flush-back filter, in particular for the filtration of oil, having filter elements (filter cartridges) arranged in a circle in the filter housing and a flushing member rotatable around the filter axis for the back-flushing of filter elements with the filtrate. According to the invention said filter elements are arranged on at least two concentric circles within the interior of said filter housing whereby said filter elements lying on one circle are located in the gaps between said filter elements lying on the other circle. For back-flushing of said filter elements horizontal on the concentric circle, there is a common flushing member below and with a small radial dimension, which is driven by a rotary drive. The back-flush filter has at least fourteen to twenty filter elements. Furthermore, a safety filter is arranged on the interior of the filter housing, which encircles said filter elements.

    Abstract: A liquid filter apparatus in which a plurality of filter units are disposed in a vessel with each of the filter units comprising a perforated tube and a filter material extending around the tube. A collection manifold is located in the upper portion of the vessel and communicates with the tubes of the filter units for receiving the filtered liquid. A cover is provided separate from the manifold for the vessel and the filter units can be disposed into at least two groups extending in a vertically stacked relationship.

    Abstract: In a filtering apparatus, a tube guide is employed for positioning a filter cartridge on a seating member. The tube guide comprises an elongated member which projects upwardly to guide the filter cartridge into registry with the seating member. A lower fastening portion of the tube guide includes a stop which engages a top portion of the seating member to prevent downward movement of the tube guide. A snap-lock on the tube guide engages the bottom of the seating member to prevent upward movement of the tube guide.
