Problems solved by technology

When this fastening works in a permissible manner, depending on the degree of tightening or the torque applied to the fastening collar, the threaded collar will move between different fuel inside the device, bringing uneven load
In addition, threads are subject to various fluid and particulate matter which can seriously compromise the integrity and efficiency of thread engagement

Embodiment Construction

[0025] refer to Figure 1-Figure 3 A typical filter cartridge having features of the present invention is described and marked with the numeral 10. exist Figure 4-Figure 8 expressed in and Figure 1-Figure 3 A specific example of a filter base assembly that fits into the filter cartridge and is marked with the numeral 80. exist Figure 9 and Figure 10 A specific embodiment of a retaining collar suitable for securing the filter cartridge 10 to the base assembly 80 is shown in and marked with the numeral 100.

[0026] figure 1 is a cross-sectional view of a filter cartridge 10 including a first housing portion 12 connected to a second housing portion 14 along a peripheral roll interface. The first housing portion, or end cap 12 has a smaller diameter than the second housing portion 14 . figure 1 Among them, the metal sheets forming the respective housing parts of the rolling interface are indicated by dotted lines around the filter cartridge 10 near the rolling interfac...

Abstract

The filter device of the present invention uses radial interference between the receiving portion (12) of the cartridge housing (12, 14) and the receptacle (87) of the base (80). This radial interference is created between the tapered end cap (12) of the filter cartridge (10) and the substantially cylindrical inner surface (95) of the base receptacle (87). The cartridge end cap (12) is tapered so that the interference increases as the cartridge is pushed into the receptacle through the retaining collar (100). The tight fit improves resistance to vibrations and shocks acting on the filter unit. The metal-to-metal contact at the interference also provides a reliable electrical connection between the base (80) and the filter cartridge (10) to prevent static build-up within the filter cartridge.

Description

technical field [0001] The present invention relates to fuel filters generally used in connection with internal combustion engines. In particular, it relates to a base receiver having a replaceable fuel filter cartridge for removing foreign particles from a filtering device and / or for separating moisture from a fuel supply system of an internal combustion engine. Background technique [0002] Fuel filtration systems associated with the present invention typically use disposable filter cartridges that are replaced at pre-set intervals of filter use. The replaceable filter cartridge is typically secured to a base that forms inlet and outlet connections between the filter cartridge and the fuel supply system. A number of retention systems are used in order to secure the filter cartridge to the base and allow the filter cartridge to be moved for replacement purposes. [0003] Filtration devices associated with the present invention are typically mounted on motor vehicles such ...
