摘要： A water drain valve (20) for use in cooperation with a fuel filter having a water separation capability includes a valve housing (23), a flow-control piston (22) disposed within the valve housing (23), a first sealing grommet (60) defining a water flow path into the valve housing (23), a second sealing grommet (60a) defining an air flow path out of said valve housing (23) and a spring-biased control lever (21) assembled to the valve housing and cooperating with the flow-control piston (22) so as to rotate the piston (22) from a drain valve normally-closed condition to a drain valve normally-open condition. The valve housing (23) is a unitary casting having a sidewall (39) defining first (41) and second (42) flow apertures, one of which (42) receives the first sealing grommet (60) and the other of which receives the second sealing grommet (60a). The flow-control piston (22) includes a first part-spherical portion (32) which includes a water drain passageway (35) therethrough leading to a drain opening (43) which is defined by the valve housing (23). The flow-control piston (22) also includes a second part-spherical portion (33) defining an air flow passageway (36) therethrough leading from the drain opening (43). In the normally-closed condition, the flow-control piston (22) is turned such that the first part-spherical portion (32) closes the flow communication between the water drain passageway (35) and the water flow path. Concurrently, the second part-spherical portion (33) closes the flow communication between the air flow passageway (36) and the air flow path. In the opened condition, there is flow communication between the water drain passageway (35) and the water flow path and between the air flow passageway (36) and the air flow path for draining water from the fuel filter and providing vent air into the fuel filter.

摘要： In general, this invention relates to supplemental coolant additive for use in cooling systems, for example, in diesel engine cooling systems. The supplemental coolant additive includes a C 4 -C 6 dicarboxylic acid, preferably adipic acid, and optionally a C 9 -C 12 aliphatic dicarboxylic acid an aromatic monocarboxylic acid, an aromatic dicarboxylic acid and salts of these acids. The supplemental coolant additive also can include a variety of other additives including molybdate salts, nitrate salts, nitrite salts, silicate salts and buffering agents. The supplemental coolant additive is preferably provided as a solid additive or a liquid concentrate. The supplemental coolant additive is preferably added to the liquid coolant over time to provide increased coolant life. Further the supplemental coolant additive provides enhanced anti-corrosion protection in cooling systems that include hard water.

摘要： A centrifugal separator (20) for removing particulate matter from a fluid includes a base (30) defining inlet (41), an outer shell (31) assembled to the base (30), a stationary centertube (34) assembled to the base (30), and a rotor assembly (20a) which is mounted onto the centertube (34) and positioned within the outer shell (31). The rotor assembly (20a) is bearingly mounted to the centertube (34) for rotation about the centertube (34). The rotor assembly (20a) includes a rotor shell (26), a cone-stack assembly (24), and a retention-medium sleeve (21) positioned between the cone-stack assembly (24) and the rotor shell (24) and the rotor shell (26) for receiving and retaining particulate matter which is centrifugally from the fluid being "processed" by the centrifugal separator (20). A water-absorbent material is included as part of the retention-medium sleeve (21), whose preferred material is a high-void medium of at lest 70 per cent. An additional retention-medium member formed into a coil-like shape is positioned between the cone-stack assembly (24) and the base (30). The base (30) includes a pair of tangential flow jet nozzles (50,51) which are used for driving the rotor assembly (20a).

摘要： A cone-stack centrifuge for separating particulate matter out of a circulating liquid includes a cone-stack assembly which is configured with a hollow rotor hub and is constructed to rotate about an axis. The cone-stack assembly is mounted onto a shaft centertube which is attached to a hollow base hub of a base assembly. The base assembly further includes a liquid inlet, a first passageway, and a second passageway (174) which is connected to the first passageway. The liquid inlet is connected to the hollow base hub by the first passageway. A bearing arrangement is positioned between the rotor hub and the shaft centertube for rotary motion of the cone-stack assembly. An impulse-turbine wheel is attached to the rotor hub and a flow jet nozzle (172) is positioned so as to be directed at the turbine wheel. The flow jet nozzle (172) is coupled to the second passageway (174) for directing a flow jet of liquid at the turbine wheel in order to impart rotary motion to the cone-stack assembly. The liquid for the flow jet nozzle (172) enters the cone-stack centrifuge by way of the liquid inlet. The same liquid inlet also provides the liquid which is circulated through the cone-stack assembly. A honeycomb-like insert (170) is assembled into the flow jet nozzle (172) in order to reduce inlet turbulence and improve the turbine efficiency.

摘要： A fluid filter (20) or filtering a circulating fluid includes an outer shell (21) having a closed first end (31) and opposite thereto an open second end (32) which is defined by a peripheral edge (35). The outer shell (21) further includes a surrounding sidewall which defines a hollow interior and a filter cartridge (23) is positioned within the hollow interior. A nutplate (22) is positioned in the open second end (32) and is assembled to the outer shell (21) with the peripheral edge (35) of the outer shell (21) being formed over a portion of the nutplate (22). A floating annular retainer (27) is positioned adjacent the nutplate (22) and in cooperation with the formed peripheral edge (35) creates an annular receiving channel (59). An annular gasket (26) is placed in the receiving channel (59) and is sized such that there is a side-to-side compressive fit established between the annular gasket (26) and the retainer (27) and a similar compressive fit is established between the annular gasket (26) and the formed peripheral edge (35).

摘要： A filter seal (141) for a cylindrical air filter (140) includes a polyurethane member which is configured with two primary portions (141a, 155). One portion (141a) is an annular body which is formed with an annular receiving channel (154), which is sized to receive one end of a corresponding filter element (142). The other portion (155) is an annular sealing lip disposed in spaced relation to the receiving channel (154). This sealing lip includes a ribbed, radial-sealing surface and a convex, axial-sealing surface (164). The radial-sealing surface provides sealing contact with an outlet portion of the housing by means of tension while axial sealing is achieved by compression of the axial-sealing surface against a generally planar surface of the housing. In addition to these two modes of sealing engagement, differential pressure forces cause the sealing lip to press tightly against the housing to enhance the sealing.

摘要： A high-pressure filter assembly which includes a cover or nutplate secured to a housing via a sidewall portion of the housing deformed into a groove formed in the cover sidewall. The cover and housing are formed such that the cover can be properly seated upon the housing prior to seaming without special locators or beads formed in the container sidewall. A method and apparatus for forming the filter assembly are also disclosed.
