Abstract: Filters that remove particulate and other solids from fluids often come in various sizes and include various types of seals. However, filter bases to which the filters are attached are generally manufactured to accommodate only one specific size of filter including one type of seal. A filter base of the present invention includes a filter attachment portion and a sealing portion. In order to expand the different sizes of filters that the filter base can accommodate, the sealing portion includes a first annular sealing surface with a relatively small diameter and a second annular sealing surface with a relatively large diameter. The two sealing surfaces can be any combination of radial and a face sealing surfaces. The filter base is used for filtering fluids, such as fuel, in an internal combustion engine.

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 fluid filter housing for receipt of a fluid filter element and for threaded attachment to a mounting base includes a unitary, molded plastic shell, an annular, threaded nutplate, and a plastic weld ring. The plastic shell defines a hollow interior for receipt of the fluid filter element. The plastic shell also defines one side of an O-ring groove. The threaded nutplate includes a groove-side surface that defines a second side of the O-ring groove. The weld ring is securely joined to the threaded nutplate by co-molding and is securely joined to the shell by a spin weld process. The weld ring provides a third surface for the O-ring groove. As such, three separate components are used to create an inwardly opening three-sided annular groove for receipt of an annular seal for sealing an interface between the fluid filter housing and the mounting base.

Abstract: An environmentally friendly dual lube venturi filter cartridge which has no metallic components. A plastic centertube having a venturi section supports a bypass filter element on standoffs molded into the centertube. An outer concentric full flow filter element surrounds the bypass filter. The full flow filter is supported on a plastic centertube which creates a gap between it and the bypass filter. A first bypass filter endcap both seals the bypass filter and provides standoffs for allowing full flow oil around the bypass filter. The standoffs thus split the full flow which progresses through the primary filter in two paths, a primary path around the bypass filter and into the centertube, and a bypass path through the secondary filter and the venturi. Plastic upper and lower endcaps carry grooves for simple sealing gaskets, a radial seal gasket on the bottom which seals against both the endcap which carries it and a flange in the housing, and an axial seal gasket at the top.

Abstract: An oil filter has a drain hole, which is internally blocked with a valve member. When oil remaining in the oil filter is drained, a drainpipe is inserted into the drain hole, so that the valve member is displaced and remaining oil is drained from the drain hole. This valve member has an annular recession to steadily support an upper end of the inserted drainpipe. Therefore, gripping force of the drainpipe is enhanced without decreasing draining performance. The drainpipe and the oil filter are connected with each other via a seal member that is provided to the oil filter. The drainpipe 80 has a removing means that holds at least a part of the seal member to pick the seal member off the oil filter, when the inserted drainpipe is detached from the drain hole. Thus, the seal member can be removed simultaneously with the drainpipe from the oil filter.

Abstract translation: 油过滤器具有排水孔，其内部被阀构件封闭。 当油滤清器中残留的油被排出时，将排水管插入到排水孔中，使得阀构件移位，剩余的油从排水孔排出。 该阀构件具有环形凹部以稳定地支撑插入的排水管的上端。 因此，排水管的夹持力增强而不降低排水性能。 排水管和油过滤器通过设置在油过滤器上的密封构件相互连接。 排水管80具有除去装置，当从排水孔分离插入的排水管时，保持至少一部分密封构件以将密封构件从油过滤器上取出。 因此，密封构件可以与排油管同时从油过滤器去除。

Abstract: A fluid filter constructed and arranged for threaded engagement with a fluid-delivery head for the filtration of an incoming fluid includes a molded plastic shell having a sidewall formed with a retaining ridge, a closed end and an opened end surrounded by a series of external threads, a fluid filter media pack installed into the fluid filter shell, the media pack including filtering media and an upper endplate bonded to the upper end of the filtering media, wherein the upper endplate includes a peripheral lip that is constructed and arranged to snap into position axially beneath the retaining ridge. The threaded engagement between the fluid filter shell and the fluid-delivery head eliminates the need for any nutplate.

Abstract: A fluid filter assembly including a filter housing, a filter basket and a filter element and method of use. The filter basket has an unexpanded condition which allows it to be inserted into the fluid filter housing. During filtering operations, the filter basket expands and engages the interior surface of the filter housing at predefined locations. Filtered fluid discharged from the basket may flow between the filter housing and filter basket between the predefined locations of engagement. Radially outwardly extending projections on the filter basket may be used to engage the interior surface of the filter housing. The fluid element may include a bag filter.
