Embodiment Construction

[0036] Filter assembly 10 of FIG. 1 is representative of a fuel filter cartridge including a prior art drain valve insert 100 . Figure 2 shows an alternative prior art filter cartridge with a drain valve insert 200. 3-5 illustrate components and assemblies of an exemplary discharge valve insert 300 according to aspects of the present invention. The discharge valve insert 300 is an assembly formed by assembling the threaded nut 70 into the formed sheet metal body 20 . The thickness of the sheet metal making up the illustrated sheet metal body 20 is approximately 0.036". The incorporation of nuts into the discharge valve insert according to the solution of the present invention reduces the need for manufacturing a Cost and complexity of bleed valve inserts with threaded anchor points.

[0037] Square thread nuts such as 70 are mass-produced nuts and are commercially available at low cost. Nut 70 has a central opening 72 defined by a threaded surface 74 . As the central, thre...

Abstract

A drain valve insert (300) employs a stamped sheet metal body (20) to support a threaded nut (70) in an elevated position over the drain opening of a filter cartridge. Multiple fluid flow passages (80) are defined between the polygonal periphery of the nut (70) and the generally cylindrical sheet metal body (20) of the insert (300). The insert body (20) defines ledges to support the nut (70) at its periphery corners and includes structures that prevent rotation of the nut relative to the insert body (20). Retaining arms (24) project upwardly from the insert body (20) and are bent over the nut (70) to axially retain the nut (70) seated against the ledges. The insert body (20) and the nut (70) are inexpensively formed in separate automated operations. Assembly of the nut (70) into the insert body (20) may also be automated.

Description

technical field [0001] The present invention generally relates to devices for filtering and separating fluids. More particularly, the present invention relates to fuel filters for removing foreign particles and separating water from the fuel supply of internal combustion engines. Background technique [0002] Fuel filters typically use disposable filter cartridges that are replaced at predetermined intervals of filter use. A wide variety of fuel filter cartridge configurations and orientations are available. The replaceable core is typically secured and / or locked to the base by a locking mechanism that is releasable to allow removal of the core for replacement. [0003] US Patent No. 5,017,285, assigned to the assignee of the present invention, discloses an inverted fuel filter assembly using a base mounted to a vehicle and a disposable filter cartridge suspended directly below the base. The core has a shell made of a pair of cup-shaped segments joined along a roll gap. ...
