摘要： A fuel system for a diesel truck has a first fuel tank (80) and a second fuel tank (82). A siphon line (90) is open to the lower portions of the tanks and extends above the upper portions of both tanks. A manually operated priming pump (98) is used to remove air from the siphon line. Fuel is delivered from the first tank to the engine of the truck through a fluid delivery line (84). As fuel is drawn from the first tank, the fuel levels in the tanks equalize as the result of flow through the siphon line. Fuel not consumed by the engine is returned through an overflow line (86). The returning fuel is warmed as a result absorbing energy during pumping and having been in close proximity to the engine. A three-way control valve (88) directs the warm returning fuel to either the first or second fuel tank in response to the temperature sensed by a temperature sensor (94). In winter, the system operates to keep the fuel delivered from the first tank to the engine warm, and in summer prevents the fuel from becoming too hot.

摘要： A crankcase oil spray nozzle for cooling the crown of a piston of an internal combustion engine is assembled from relatively few stamped principal housing components which are assembled in a sandwich-like, low-profile configuration. The components cooperate to form a nozzle passageway which extends from an integrally formed well to the nozzle orifice. An indentation is coined in one component to form the nozzle passageway and the nozzle orifice.

The housing includes a removable cover, and a fitting including an internal central conduit extending along the central axis of the housing. The central conduit is bisected along its length and has a pair of flow channels connected to a pair of ports in the fitting. Another port is provided in the fitting and a still further port is provided in the housing. The filter element includes a first circular imperforate end cap, and a second annular imperforate end cap dimensioned to receive the central conduit.

摘要： A filter assembly includes a base and cover member which together enclose a planar filter element. Each of the base and cover members has a planar face with a central overpressure opening for an overpressure valve, and a radially-extending channel extending from a port on the side of the base or cover member radially inward to the central overpressure opening. The channel is open along the surface of the planar face. According to a first embodiment, a plurality of radially-extending ribs are disposed in even, spaced-apart relation around the planar surface. The ribs define radial fluid flow paths for even distribution of fluid across the planar face, as well as support a surface of the planar filter member. According to one aspect of this embodiment, a central support rib is suspended along the open side of the channel, and is attached at its radially outer end to an outer annular frame, and at its radially inner end to a ring surrounding the central opening. One or more support trusses intersect the central support rib to add rigidity and strength to the rib. According to another aspect, one or more trusses extend substantially perpendicular to the radial channel for support of the filter element along the channel. According to another embodiment of the present invention, a plurality of cylindrical posts extend outwardly from the planar surface to provide fluid flow paths across the planar surface and for support of the filter element. One or more of the posts are disposed along the side edges of the radial channel or a central rib is provided along the channel for support of the filter element along the channel.

摘要： A head (10) for mounting a replaceable spin-on fuel filter element (12) for use in a vehicle fuel system, includes an inlet (18) and outlet (76). The inlet is connected in the head to a second chamber (24) through a first check valve (26). The first check valve enables flow only from the first chamber to the second chamber. The second chamber includes a manually actuated pump (28). The second chamber is connected to a fluid in-flow area (64) of the element through a second check valve (62). The second check valve enables flow only from the second chamber to the in-flow area. The first chamber is also connected to the in-flow area of the element through a third check valve (84). The third check valve enables flow only from the first chamber to the in-flow area of the element. To remove air from a newly installed element and to prime the fuel system of the vehicle, the manual pump is cycled. The pump moves fuel from the inlet of the head through the first check valve, second chamber and second check valve, pushing fuel and air through the element to the outlet. When the manual pump is used, the third check valve remains closed. When the engine of the vehicle is started, vacuum is drawn on the outlet of the head. Fuel then flows directly to the in-flow area of the element from the first chamber in the head through the third check valve, bypassing the pumping means.

摘要： A fuel filter assembly (10) has a head portion (12) and an element portion (14) enclosing a replaceable cartridge (18). The assembly has a first inlet port (22) which accepts fuel from a tank (90) and filters it by passage through a screen (43) supported on a tube (36). The fuel that has been filtered by passage through the screen is delivered from the assembly through a first outlet port (24) for delivery to a lift pump (96). Fuel from the lift pump is returned to the fuel filter assembly through a second inlet port (26). The fuel is finely filtered by passage through a loop of filter media (60). Clean fuel is delivered from a second outlet port (28) to an engine (104). Contaminants separated from the fuel by passage through the screen and the media loop are collected in first-and second sump areas (78), (80) of the filter housing respectively. An alternative embodiment (110) includes a prefilter screen (158) integral with a replaceable cartridge (118).

摘要： A fuel filter comprises a head (96) having an inlet (100) and an outlet (102). The head is connected to an element (266) by a nipple portion (186) which has a valve element (196) therein. An actuating projection (222, 272) is engageable with said valve element to open flow through said nipple portion when the correct element is attached hereto. The actuating projection is further supported on a central portion (220, 276) which prevents connection to a nipple portion that extends too far into the element. According to a further embodiment, the filter includes a housing (412) with a removable element (424) mounted therein. The housing has an inlet port (414) in direct fluid communication with a chamber (418). The outlet port (416) is in direct fluid communication with a central standpipe (422). The standpipe has a flow element (442) movable therein for controlling the condition of flow openings (436) in the standpipe. The cover further includes a cover projection (482) for supporting a projection (478) on end cap (460) of the filter element, which opens flow into the standpipe only when the element is installed. A centering wall (486) is also provided on the cover which is received within a recess portion (704) of a well area of the end cap (460). The removable element can include first and second filter media rings (426, 716) where fluid is introduced between the rings and flows radially inward through the first media to a first outlet (416), and radially outward through the second media ring to a second outlet (710).

摘要： A fuel conditioner of the type having a housing defining an inner chamber for receiving a filter element, inlet and outlet ports in the housing for establishing a flow of fuel to and from the chamber, and a heater for raising the temperature of the fuel between the inlet and outlet ports. The improvement comprises a baffle plate situated within the housing between the inlet and outlet ports, for directing substantially all the flow of fuel as a thin layer against a selected interior portion of the housing. The heater is situated on the housing exterior adjacent the interior portion of the housing containing the baffle. The fuel passing through the thin passageway therein reaches its highest velocity in the conditioning unit. Particularly if the flow boundary area defined by the housing and the baffle plate is large compared with the volume of the passageway, very high heat transfer from the heating element to the fuel in the passageway is achieved. Preferably, the heater includes an electrical resistance heating element having a positive coefficient of resistance with increasing temperature of the element.
