Definitions

  • This application relates to fuel valves and provides an in-line valve with over-pressure and over-vacuum relief functions.
  • Fuel valves typically have complicated housings and assembly processes. Many require angles to accommodate the various components. Angle flow valves can suffer from undesired pressure changes because of angles necessary to accommodate the various components and port requirements. The bulkiness of angle valves make them more difficult to control and to find space for in a system.
  • An in-line valve comprises a solenoid assembly comprising a hollow tubular pole piece, a bobbin, a coil, and flux collection plates.
  • a cylindrical armature is within the pole piece, the armature comprising a hollow central passageway and a step in the hollow central passageway.
  • a spring is in the central passageway and a seal is seated against the spring to bias the seal against the step.
  • a method for controlling the in-line valve comprises selectively powering the solenoid assembly to move the armature between a sealed position, where a second seal blocks a port, to an open position, where the armature moves away from the port.
  • Figure 1 is a cross-section view of an in-line valve.
  • Figure 2 is a cross-section of another in-line valve.
  • Figure 3 is a cross-section of another in-line valve.
  • Figure 4 is a cross-section of another in-line valve.
  • Figure 5 is a cross-section of another in-line valve.
  • Figure 6 is a view of an armature and seal.

  • the solenoid assembly surrounds valve components, which more effectively utilizes the space inside the solenoid and yields a more compact assembly.
  • o rings 430 and 530 efficiently restrict leak paths within the device. Fluid can be coupled from valve port 400 to valve port 500 with minimal sealing mechanisms, resulting in material and size savings.
  • pole piece 1 10 is integrated with the valve port 500 as a unitary member, and pole piece 160 is integrated with valve port 400 as a unitary member.
  • the integration eliminates yet another leak path and another need for sealing mechanisms.
  • the port connections can be, for example, press-fit, quick-connect, snap fit, or barbed end.
  • pole pieces 1 10 and 160 are over molded and surrounded by an encapsulating housing 800.
  • the valve ports 400 and 500 are unitary with the encapsulating housing 800.
  • Leak path elimination can be augmented by using a bonding agent, locking feature, tortious flow path, geometry or a combination thereof between the over mold and pole pieces 1 10 & 160. If needed, the augmentation can also be applied to the flux collectors, such that the over molding is applied to contact or surround portions of the flux collectors, the flux collectors including the bonding agent, locking feature, tortious flow path, geometry, etc.
  • a tortious flow path permits inflow of molding material in to a gap, and this can reduce valve weight by removing metal from the flux collector and or pole piece and then filling it with a lighter weight molding material.
  • the port connections can be, for example, press-fit, quick-connect, snap fit, or barbed end are integrated to the solenoid assembly via the over molding.
  • the pole pieces 1 10 & 160 can be a magnetic material, for example, a 400 series stainless steel or a low carbon steel. They can be plated to protect against corrosion. The pole pieces can be stamped or formed. Armature 200 is attracted to pole piece 160 when the coil 125 is energized. Figures 3 and 5 illustrate the activated condition, whereby armature 200 overcomes the spring force of armature spring 300. Wiring and power supply connections for the solenoid can be provisioned and molded with the encapsulating housing 800.
  • pole piece 160 can be a different material, such as brass or bronze or another material.

  • the space can receive a guide tube 320.
  • the pole piece 1 10 extends within the solenoid assembly 100 to guide the armature 200 via an extension piece.
  • the guide tube adjoins the extension piece of the pole piece, and the second pole piece 160 adjoins the guide tube 320.
  • Guide tube 320 can be non-magnetic. A bearing material like brass or bronze can be used.
  • the guide 320 tube can be plastic and molded as part of bobbin 120.
  • the guide tube acts as a secondary bearing for the armature 200.
  • the guide tube can have crush features on one or both ends that can be deformed to keep the valve assembly loaded together.
  • the guide tube 320 can maintain a component dimensional stack up that is the same as the standoff length.

  • the armature 200 is fluted by comprising external ridges 216.
  • the ridging forms fluid passageways between the pole piece 1 10 and the armature 200 to permit a high rate of fluid flow.
  • Radial gaps 204 exist around the center line X of the armature 200, and between the center line X of the armature and the surrounding solenoid components, because the external ridges 2016 are spaced circumferentially around the center line X of the armature.
  • the armature 200 can have slots 206 to permit fluid flow from the hollow central passageway 210 to in between the external ridges 216.
  • the armature can comprise a solid body 292 to fluidly separate central passageway 210 from the radial gaps 204.
  • Solid angular face 290 shown in Figures 6B & 7A, provides an uninterrupted conical pole surface, which increases the pole area to acquire magnetic force compared to the clawlike extended ends 212 of Figure 6A.

  • the fluted armature enables fluid flow in-line. No turns or angles are needed in the flow path in order to implement the solenoid control. In this way, the valve design is simplified in to a central carriage.
  • the armature is assembled and customized and is a central carrier loaded in to the solenoid assembly. Fluid can flow easily around the external ridges 216 when the armature is positioned for that flow path, as by activating or deactivating the solenoid, or as by slots 206 in body 292.
  • the hollow central passageway 210 within the armature provides another fluid passageway.
  • the central passageway 210 can be sized to restrict flow, as shown in the constricted area near step 240 in Figure 3. Thus, diameter changes can be used for controlling pressure differential across the in-line valve.

  • the solenoid assembly can be further configured to move the armature 200 from a sealed position, where the second seal 600 blocks valve port 400, to an open position, where the armature is centered in the solenoid assembly 100.
  • a method for controlling the in-line valve comprises powering the solenoid assembly to move the armature 200 between a sealed position, where the second seal 600 blocks valve port 400, to an open position, where the armature is centered in the solenoid assembly, to a metered position, where the third seal 610 meters fluid flow at a second port.

  • Seal 260 is, for example, configured for over pressure relief (OPR) and the second seal 600 is configured for over vacuum relief (OVR).
  • OPR over pressure relief
  • OVR over vacuum relief
  • the armature 200 moves from port 500 towards port 400, vapors from the tank flow to the canister.
  • the solenoid assembly is de-energized, the armature spring 300 pushes the armature 200 toward the port 500.
  • Second seal 600 abuts port 500. If an over-vacuum occurs in the tank, the armature spring 300 is overcome by the vacuum, and seal 600 unseats to alleviate the vacuum. If an excess pressure from the tank occurs, seal 260 unseats. Vapor flows through the central passageway 210 and through an orifice in second seal 610.
  • the ports 400 and 500 cooperate to position the armature 200, and at least one port extends in to the solenoid assembly to form the pole piece.
  • the pole piece is integrated into the port end.
  • the ports 400, 500 can be a metal such as a magnetic stainless steel. While shown with fluid port connection hubs, it is possible to form a more cost effective version, with truncated port necks 520, 420 at both sides of the solenoid, as shown in Figure 5.
  • the entire solenoid could be over- molded and the port connections included as part of the over-mold, as shown in Figure 5. Attachment ports 810 are likewise included with the over-mold.
  • Figures 1 -5 benefit from an additional adjustment feature.
  • a retaining ring is modifiable to adjust the spring force, as by adjusting the width of the retaining ring.
  • a press- fit can be used. This is shown in Figures 3 and 4, where spring seat 280 is pressed in to the armature to adjust spring tension.
  • Figures 1 -5 permit a pulse-control method to meter fuel vapor.
  • the valve is pulsed periodically to control vapor pressure in the tank. This permits quick re-fueling, because the vapor pressure never exceeds a predetermined amount during vehicle operation. And, make-up air is permitted entry to the tank during the pulsing.
  • safety mechanisms in the form of the seals 260, 270 or 600, permit necessary over pressure and over vacuum relief.
  • This bleed can be through seal 600.
  • Relief air, or tank fluid such as fuel vapors, can bleed through armature 200.
  • the diameter of the seals, and presence or absence of orifices is based on fluid dynamics and pressure control.
  • a sensor determines if fluid pressure in a tank, such as fuel in a fuel tank, is above a predetermined threshold in step S902. If not, fluid pressure continues to bleed through armature 200. If tank pressure is above the threshold, the process moves to step S904 to pulse the solenoid power to unseat the armature 200.
  • the pulsing can be according to a pressure decay function.
  • the pressure decay function can permit fine metering, as described, or complete depressurization of the tank, such as for refueling the tank.
  • the solenoid control can be done to prevent upstream corking of other valves.
  • the process returns to step S900, as by unpowering the solenoid.
  • step S904 continues solenoid control to shuttle armature 200 as needed between seated , intermediate, and unseated positions. Returning to a seated position during pulsing permits fine metering, as by controlling a small "slug" of fluid.
  • a pulse control method prevents corking of other valves in the system by finely controlling the vapor pressure. Users require quick depressurization to ensure the fuel tank is safe to fill by the time the driver reaches the tank to open it. While it is possible to use a two stage valve and orifice to control depressurization, the pulse control method eliminates the need for a second stage valve. An on/off style valve could give too much vapor flow during a fuel fill event, which would cork the fill unit vent valve and disrupt overfill protection of the fuel tank. If such a refueling valve reseats, instead of the needed full vapor flow, no flow is permitted, and the fuel fill event is hampered.
  • a lower solenoid power can be used.
  • Further weight reductions are possible by implementing a perforated sleeve 140, shown in Figure 8.
  • over-mold material can be lighter than traditional solenoid can materials, and can be lighter than seals.
  • perforations 1400 can permit ingress of molding fluid in to air gap 150.
  • the molding fluid can thus create a chemical barrier and protect the solenoid from corrosion.
  • the molding fluid can leak in to other gaps at pole pieces 1 10, 160 and flux collection plates 130, 131 and create fluid leak path sealing upon curing the molding fluid.
  • a sheet material can be, for example, stamped and roll- formed.
  • the sleeve can be attached to the solenoid assembly by, for example, crimping or joinery techniques such as the illustrated dove-tail tab 1404 in notch 1402.
  • Extensions 1 144 can be included to catch against flux collection plates 130, 131 or pole pieces 1 10, 160. Spaces between the extensions 144 permit wiring for the solenoid to pass through the sleeve 140.
  • the low material use and elegant design of the in-line valve permits lower solenoid power, resulting in a smaller coil assembly and smaller over-all valve. While circular perforations 1400 are shown, other shapes, such as square, oval, rectangular, crenelated, etc. are possible.
  • valve port 400 to valve port 500 By controlling the diameter of the armature body 292, which in figures 7 & 8 is solid, by controlling the diameter of central passageway 210, and by controlling the diameter of seal orifices 605, 610, fluid pressure differentials from valve port 400 to valve port 500 can also be tailored. 290
  • the pulse control method can be more complex to include a metering function.
  • a finer mass resolution is achieved by partially blocking flow to the port 500 or by designing the third seal 610 to provide full port blockage. While it is possible to use a voltage driven solenoid assembly for armature control in Figures 1 -4, it is possible to use a current driven solenoid assembly for Figure 1 to facilitate the finer control.
  • Fine control in the pulse control method is possible because the in-line valve is easier to actuate than an angle valve.
  • the in-line valve can have its stroke length tailored more precisely.
  • the armature 200 can be moved between a full right, a middle, and a full left position, with resulting blocking and unblocking of the ports 400 and 500.
  • Figures 1 & 4 show the in-line valve at rest (de-energized).
  • Figure 2 shows the armature in a centered (partially lifted) condition.
  • Figures 3 and 5 show the armature 200 in an energized condition with the solenoid assembly 100 powered and the armature spring 300 spring force overcome.
  • the in-line valve has a smaller foot-print than angle-flow valves because the valve components are within the solenoid assembly. Angle-flow valves stack the solenoid over the valve components and need additional material to create the port bends for the angles. The in-line valve is more compact because of the stackable nature of the ports to the flux collectors.
  • a sleeve 140 creates electrical connectivity between the flux plates 130, 131 .
  • the sleeve 140 includes fingers 144 bent around the ends of the solenoid assembly. The fingers 144 clamp extensions 402, 502 of the valve ports against the flux collection plates 130, 131.
  • the flux collection plates 130, 131 are stacked against the bobbin 120.
  • the configuration is a highly efficient drop-in and stacking assembly technique. Few leak paths exist, and minimal o-rings 430, 435, 530, 535 are needed.
  • valve ports 400, 500 are integrated with the pole pieces 160, 1 10. This eliminates o-rings 435 & 535. O-rings 530 & 430 remain to seal the pole pieces 1 10, 160 against the bobbin 120. With the internal leak path efficiently sealed, the flux collection plates 131 , 130 can abut the sleeve without additional sealing, though a bonding agent or seal can be used. Flux collection plate 131 press-fits to sleeve 140 to clamp integrated valve port 400 and pole piece 160 in the assembly. An air gap 150 can be between sleeve 140 and coil 125.
  • FIG. 3 While a lip 146 is shown in Figure 3, it is possible to also crimp the valve port 500 using fingers 144, as in Figure 4. Also, tabs 148 can be supplied on sleeve 140 for crimping the flux collection plate 131 , or for valve mounting or purposes.
  • Figure 5 shows an efficiently packaged and low-leak in-line valve.
  • the pole pieces 160, 1 10 are truncated and do not form the valve ports 400, 500. Instead, necks 420, 520 are included for permitting press-fitting of the flux collection plates 131 , 130 to the pole pieces.
  • the sleeve 140 does not include fingers or lips, but does abut the flux collection plates 131 , 130.
  • Sleeve 140 can be stamped or roll-formed. It can be a solid sheet material, so as to maintain air gap 150 with air. Sleeve can alternatively be slotted, meshed, or otherwise punctured to have openings to permit ingress of encapsulation material in to the air gap 150.
  • Encapsulating housing 800 integrally forms the valve ports 400, 500 and attachment port 810.
  • Attachment port 810 can be, for example, an electrical wiring port for powering the solenoid (wiring omitted for clarity), or can be a mounting expedient, such as a catch, clip, foot, screw-hole or like mounting mechanism.
  • a bonding agent, or other attachment augmentation means can be applied to the pole pieces 160, 1 10, flux collection plates 131 , 130, and sleeve 140 as needed to assist with connectivity and leak path sealing.
  • a central carriage can be assembled.
  • the armature can be customized with seals 270, 260, 610, 600, with or without orifices 615, 605.
  • Armature spring 300 size and force can be selected.
  • the armature is assembled using simple drop-in techniques, and the carriage is assembled by inserting the armature in to the solenoid assembly.
  • the carriage can be oriented for over pressure or over vacuum relief capabilities.
  • Port connection type and attachment ports 810 are selected easily in the molding crib. Die lock is avoided by eliminating turns. Necking up or necking down can be achieved using tooling connected to form ports 400 & 500. Encapsulating as a final assembly step thus presents great advantages.

Un procédé de commande de la soupape en ligne consiste à alimenter sélectivement l'ensemble à solénoïde pour déplacer l'induit entre une position fermée dans laquelle un second joint d'étanchéité bloque un orifice, et une position ouverte dans laquelle l'induit s'éloigne de l'orifice.
