Abstract: A filter cartridge which is environmentally friendly in that it is made up of components which are all incinerateable. The ends of a filter element are sealed using potting compound and plastic endcaps. The upper endcap, which is closed, has a pressure relief aperture associated therewith to prevent bowing. In a plugged filter condition the high-downward pressure introduced on the upper endcap is compensated by providing the cartridge with centering ribs which bottom on an associated ledge in the housing to provide a positive stop for the top endcap, preventing it from being driven down into and through the filter element. Rubber gaskets are associated with the respective endcaps, and are reliably secured to the endcaps by being snap fit into grooves molded into the plastic of the endcaps. The lower endcap utilizes a simple radial seal gasket which is both highly effective and also positioned to avoid structural crushing forces on the cartridge. A keying system prevents the installation of improper filters.

Abstract: A liquid filter, such as an oil or gas filter, is provided which has a cup-shaped cylindrical filter housing to be mounted in a vertical orientation, with a releasable cover closing the filter housing. A liquid inlet passage and a liquid outlet passage are provided at the housing. A replaceable, substantially hollow cylindrical filter insert is vertically arranged in the housing. The filter insert being formed of a filter material member arranged between an upper and a lower disc. A collar, which is impervious to solid contaminants removed by the filter material member, extends from the lower disc upwardly along a part of the height of the filter insert, surrounding an outer circumference of the filter insert member. In this manner a collection chamber is formed for the filtered solid particles at the lower disc.

Abstract: A filter cartridge for a liquid is designed to be removably received in a housing and comprises a tubular filter element of zig-zag folded paper having two ends that are secured to two respective flexible washers. The cartridge does not have any central reinforcement of its own and its washers co-operate directly for sealing purposes with appropriate annular bearing surfaces of a perforated rigid tube that is included in the housing: the cartridge is therefore easily discarded or degraded after use.

Abstract: The invention is an improvement in a known cylindrical, annular fluid filter cartridge of the type having a lower end cap supporting spaced, concentric filter elements. The spaced elements define an effluent path therebetween. In known cartridges of the foregoing type, the inner and outer perimeters of the end cap (or either of them) have a significant circumferential "Perimeter of engagement" which seats into a pocket with friction fit. As a result, significant force is required to remove a cartridge, especially a large cartridge, from the housing. The improvement comprises a channel (either a tube-like riser or a manifold) and a discharge port for receiving effluent, e.g., filtered water, from the effluent path. The discharge port (with its relatively small perimeter of engagement) is configured and arranged for attachment to and detachment from an outlet vent located near the bottom of the cartridge housing. Because of the relatively small engagement perimeter of the discharge port (and the resulting reduced "frictional" forces), even large water-soaked cartridges are much more easily removed from the housing as when cleaning or replacing the cartridge.

Abstract translation: 本发明是已知的具有支撑间隔开的同心过滤器元件的下端盖的圆柱形环形流体过滤器滤芯的改进。 间隔开的元件限定了它们之间的流出路径。 在上述类型的已知盒中，端盖（或其中任一个）的内周和外周具有显着的圆周“接合周界”，其以摩擦配合的方式安置在口袋中。 因此，需要大量的力从壳体中取出盒，特别是大的盒。 该改进包括从流出物路径接收流出物（例如过滤水）的通道（管状提升管或歧管）和排出口。 排出口（其相对较小的接合周边）被构造和布置成用于附接到位于盒壳体底部附近的出口孔。 由于排出口的相对较小的接合周界（和由此产生的减小的“摩擦”力）），即使是大量的浸水墨盒也比清洁或更换墨盒时更容易从外壳中取出。

Abstract: 1,273,251. Filters. CARBORUNDUM CO. 2 May, 1969, No. 22422/69. Heading BID. A sleeve-like filter element (16) of sheet material is constrained to pleated shape by having its ends clamped against outwardly extending cogs 22, 24 of a core 12 by respective segmented clamping rings 40, 42 which present inwardly extending cogs 52, 54, fitting between cogs 22, 24 (Fig. 1, not shown). The two ends of the core are joined by posts 38, and the rings 40, 42 may be similarly joined by ribs 44 or separate. Core and rings are moulded of polypropylene, and the segments of the rings in Fig. 3 are connected by integral, flexible straps 58. The rings open out (Fig. 5, not shown) to facilitate replacing the element (16), and their mating ends are secured by catch 78 or by an enclosing wire clamp (76) (Fig. 1, not shown). In Fig. 1, clamp (76) encircles axial extensions 52 of the ring, but in Fig. 10 (not shown) radial extensions support the clamp (76) around but clear of straps 58. Fig. 8 (not shown) illustrates non- integral straps (96), and in Figs. 7, 9 (not shown) ring segments are hinged together by pins (90) in slots (92). Figs. 11 to 13 (not shown) illustrate sealing the ends of the filter element between pairs of concentric gaskets or by integral rubber mouldings.

Abstract: A filter device has a filter housing (14) with a housing pot (12), which accommodates a replaceable filter element (16) and is closed by a removable lid part (32). The element material (20) of the filter element (16) separates an unfiltrate chamber (22) from a filtrate chamber (18, 43). A measurement sensing device (108) senses pressure values from at least one of the chambers (18, 22, 43), is disposed on a lid inner side (45) of the lid part (32), is at least partially guided in the lid part, and projects into the filter housing (14). At least parts of a measurement value evaluator (78) are connected to the measurement sensing device (108) and are disposed on the opposite lid outer side (42) facing the environment.
