Embodiment Construction

[0023] Referring to the drawings, wherein like numerals refer to like parts throughout the several views, a pressure resistant filter cartridge according to the present disclosure is indicated generally by the numeral 10 . Filter cartridge 10 is particularly suitable for incorporation into a fuel supply system (not shown) of an internal combustion engine, such as a diesel engine, for removing particulate matter from the fuel and separating water from the fuel.

[0024] The filter cartridge 10 is removably mounted to the filter base by a retaining ring in a similar manner to US Patent No. 6,471,070, which is hereby incorporated by reference. As shown here, the base is an inverted cup-shaped holder formed with a skirt defining a lower receiving cavity for the upper portion of the filter cartridge 10 . An elongated sleeve-shaped inner tube and a concentric sleeve-shaped outer tube extend axially downward from the center of the base. These tubes provide generally coaxial fluid co...

Abstract

A fuel filter cartridge includes a housing having a first housing portion and a second housing portion. These housing parts are generally symmetrical about the barrel axis and joined together. The first housing portion has a convex shape when viewed from the side and includes an end portion, a cylindrical side wall portion, and a transition portion connecting the side wall portion and the end portion. The end portion has an end surface forming a barrel opening coaxial with the barrel axis. The radius of the transition is 0.125 inches to 1.125 inches. Arranged within the housing is a filter which has at least one filter element.

Description

technical field [0001] The present invention generally relates to devices for filtering and separating liquids. More particularly, the present invention relates to a fuel filter for removing foreign particles and separating water from fuel in a fuel supply system of an internal combustion engine. Background technique [0002] The diesel fuel supply lacks high standards of quality control, which for diesel engines requires the incorporation of effective fuel filters in the fuel supply system. It is not unusual for diesel fuel to have large amounts of coarse particles and water present. Coarse particles can potentially permanently damage fuel injection pump components. Coarse particles can also adversely affect the performance of a fuel injection pump by impairing its ability to accurately meter fuel and deliver fuel at high pressure. The presence of water in the diesel fuel supply can cause rusting of engine components and, in severe cold conditions, can cause fuel injecti...
