Description

For being releasably attached media lines or at least one media lines and at least The connecting device for line of individual assembly

The present invention relates to it is permissible for being releasably attached at least two media lines that medium can flow through or medium The media lines flowing through and the connecting device for line of assembly, it includes：At least one inner chamber is as being used for fluidly connecting at least Two media lines or the flow path of media lines and assembly and the medium for passing through；With at least one couplings Point, it is used for reception and can be connected to or connect to the male component of media lines, wherein in the region of coupling, interior Being dimensioned so as to of portion chamber, enabling when by male component insertion and be locked in connecting device for line coupling in During appropriate location, be excessively inserting (over-insertion) for male component provides at least one insertion space；And conduit system System.

For be releasably attached i.e., for connect and at least two media lines that can flow through of separating medium or Person's media lines are known with the connecting device for line of assembly or the attachment means of assembly in the prior art.Especially exist In the vehicles, there is provided media lines are used for guiding liquid medium.Normally, there is provided connecting device for line, especially with coupling The form that socket part is divided, for coupling multiple media lines or being combined together, wherein coupling and male component are mutual Connect.These connecting device for lines are applied not only to interconnect at least two media lines, are additionally operable to connect media lines and appoint Meaning assembly or any part, the measuring unit in the region of such as motor vehicle engine or pump to motor vehicles water tank. At low temperature, the medium being had the risk freezed by freezing threat in media lines and connecting device for line is why to lead to Often for media lines and connecting device for line offer heater the reason.Often those media be conducted through media lines and Connect to its connecting device for line, due to relatively high freezing point, tended to freezing in very high ambient temperature medium, Result is that the function of the function such as vehicles can be compromised or even be interfered significantly with.Here should especially carry And aqueous solution of urea is as medium, it is pumped through media lines and it is used as the bavin with so-called SCR catalyst The NO of oil turbine_xReaction additives.SCR can be configured in this connecting device for line to couple or SCR male component, here Locate these to be used with the similar type of other media.SCR male component generally has circumference locating snap ring, and it is connecting To coupling or connecting device for line coupling during must be inserted into, until enter locating snap ring after retaining element Face is clamped in coupling access component or the state partly going up.For this purpose, need so-called being excessively inserting, i.e. with regard to couplings The excessive insertion of the actual lock position within part or the part entering coupling access component or partial inside, in order to make Clamping after retaining element is realized.This line with two media lines is described in WO 20137083274 A1 The example of road attachment means.

The freezing or duration of coagulation of medium within media lines, icicle accumulates, and it may migrate to catheter interior, Or the freezing of increase of the medium such as aqueous solution of urea positioned at catheter interior may be led to.Aqueous solution of urea is Through freezing in the temperature less than -11 DEG C.In media lines or during the freezing of the medium that is located therein, generally final in medium The maximum pressure of freezing wall of local formation freezing.Condensed medium expands.It is changed into the body of the result of solid as coherent condition from liquid Long-pending increase can be compensated at least in part, as long as the medium not yet freezing is present in media lines or connects to its circuit In attachment means.In this case, condensed medium can optionally be moved in the direction of the medium not yet freezing, herein this Only possible, until setting up pressure balance.Elongated icicle generally can only move inside media lines, here Locate this group depending on media lines or the design, media lines and connecting device for line of the connecting device for line connecting to it The configuration closed and the order freezed of the regional depending on media lines or the connecting device for line connecting to it.

By media lines with the connection with the end between media lines and assembly or at them The duration of coagulation of the medium within medium system of assembly composition of device, the separation of one or more media lines and assembly Or tie point is specifically certified as especially problematic, because long-pending under high pressure of freezing wall inside connecting device for line Tired icicle can have the result that, that is, be inserted in the icicle that the male component of there can be grown from connecting device for line Coupling extrusion is so that the plug of connecting device for line and male component connects or coupling is discharged unintentionally.This More particularly, to there is the long transmission line of 5m length, because in this long transmission line, especially big icicle can be accumulated, it is very strong Pressure under can apply ice pressure in the direction of release that connects of plug in male component and the coupling of connecting device for line Power, therefore can lead to plug to connect from the release of the coupling of male component and connecting device for line.

In order to solve this problem, for example, EP2455645A1 proposes for connecting connecing of at least two fluid media (medium)s Pressure equalizing chamber between first and second connection ends of the connector receiving element.Compressible insert is located at pressure balance In room.Compressible insert is on the inwall that some regions are resisted against pressure equalizing chamber.For the first and second connection ends Between at least one the longitudinal room fluidly connecting be provided at the inwall of pressure equalizing chamber and compressible insert it.In temperature In the case of the volumetric expansion of fluid media (medium) of degree induction, compressible insert is compressed.Pressure equalizing chamber is configured specifically For cylindrical, similarly, compressible insert is configured to cylinder.Pressure equalizing chamber is made up of plastics.Compressible Insert be reversibly deformable, herein due to fluid media (medium) condense in volumetric expansion during it is compressed, and During period, subsequent volume reduced, due to thawing, it adopts its original-shape again.Therefore, compressible insert is by bullet Property material composition, be especially made up of foamed plastics, such as closed cell foamed plastic.The surface of compressible insert is configured specifically Formed for closing or by the epidermis closing.Fluid media (medium) can be inserted through compressible from the first connection end of connector At least one the longitudinal room entering thing flow to the second connection end of connector.Compressible insert may lose over time can Compressibility, this is due to the aging of its material or even pressure balance in vertical passage provided herein in medium condenses The result of the damage of compressible insert of chamber interior.Further, since equally in pressure equalizing chamber during the defrosting of medium The region that connects of end side in dimensional measurement, connect fluidly connecting and can be present in pressure balance chamber interior between end The dielectric impedance freezing relatively long time.

Therefore, the purpose of the present invention is to develop the connecting device for line of preamble according to claim 1 further, for can Release ground connects at least two media lines or media lines and the assembly that medium can flow through, even if therefore not providing pressure Balance cylinder is it is also possible to effectively avoid male component and the coupling of any damage to connecting device for line and any connecting device for line What socket part was divided unintentionally separates.

For the attachment means of preamble according to claim 1, the realization of this purpose is because providing at least one Device its be in intermediateness between mode of operation and frozen state, during mode of operation, medium flows through media lines (one or more) and connecting device for line, during frozen state, media lines (one or more) and connecting device for line The part of the frozen volume reducing inner chamber of internal medium and/or sealing inner chamber is to prevent medium and/or ice Infiltration.This purpose be furthermore achieved that by conduit system, this conduit system includes at least one this attachment means and extremely Few two media lines or media lines and assembly or component connecting device.The exploitation further of the present invention be limited at from Belong in claim.

A kind of result, there is provided connecting device for line, is used for being releasably attached, i.e. for connecting and separating, medium can With at least two media lines that flow through or media lines and assembly, medium flow through or the connecting device for line that passes through in Portion provide its inner space or inner chamber be usually reduced as much as possible, especially by male component insertion connecting device for line with It is easy to being excessively inserting required for the locating snap ring of locking male component after the retaining element of the coupling of connecting device for line Space.In conduit system in the intermediateness between the operation under operating pressure, wherein medium flows through at least one medium and leads Pipe and connecting device for line, and the medium freezing in low environment temperature, i.e. as at media lines (one or more) With the medium ice being formed in connecting device for line, the critical zone of the inner chamber within inner chamber or connecting device for line can be use up Possibly reduce.Can be reduced in this region of correct time, i.e. when after the mode of operation in remaining state, at this Freezing of interim medium may arriving.

Advantageously, because in order to reduce the volume being excessively inserting space, there is provided restoring means, its replace male component or At least one part of person, is contacted with male component with respect to coupling or connects to male component, by this way so that It is excessively inserting space (one or more) to be reduced, and/or provides device, it is in direction of insertion to male component applying power And/or its power acting on the opposition of direction of insertion phase on male component applies counter-pressure.By male component and/or around it Potted component on power effect, the coupling in the front portion of male component and around male component connecting device for line Internal be excessively inserting space and can be reduced such that there cannot assemble medium, otherwise falling below what medium freezed When below critical-temperature, medium may lead to oppose that male component applies pressure with direction of insertion phase, and therefore due to when gathering State volumetric expansion when liquid is changed into solid, from coupling extrusion pin part.Be excessively inserting space may be provided on slotting The front portion of the leading section of head part or around it coupling in connecting device for line inside, and also may be provided on On outside, around male component radially in the outside of male component and the inner side that coupling there is provided between with And prevent the seal-packed axial direction of any leakage from coupling for the medium.There is described herein reduction is excessively inserting space or Person two is excessively inserting the measurement of the two of at least one of space.These can be pure geometry, but can also be joined Be set in the form of the insert between male component and coupling, herein not only can seriatim and also be combined with each other and carry For these measurements.Identical situation is applied to the possible measurement for reducing the direct current space within connecting device for line, directly Fluid space i.e., medium from media lines flow to another or from media lines flow to assembly process inside empty Between.

Advantageously, this device is elastic device, especially spring element, rubber element or elastomer element.By means of This elastic device, can move the potted component providing inside coupling under any circumstance, for by means of this bullet Property device carrys out the intermediate space between the outside of sealing plug part and the inner peripheral wall of coupling, thus parallel to intercalation part The Longitudinal extending in the direction in its leading section for the part is so that set around male component between male component and the inwall of coupling That puts is excessively inserting space and also can be sealed by potted component, and therefore these potted components may be located at and are excessively inserting in space.By In the commonly provided elasticity of potted component, during male component inserts the process of coupling, especially in male component During being excessively inserting, potted component can be extruded, but the result as the effect of elastic device when removing pressure, it is back to it Original-shape or be at least nearly to its original-shape or become compression shape.

Moreover, it is possible to the device of applying recuperability or restoring means axially act on the locating snap ring of male component On, especially from the side of the locating snap ring of the direction of insertion opposed orientation with male component, and the coupling in connecting device for line The inside that socket part is divided is supported.As a result, male component can be extruded in the direction of insertion of male component in axial direction, i.e. The direction entering connecting device for line is axially extruded.The element of such as shading ring its radially and/or axially Supported inside coupling, and it is axially acted on spring element, especially apply pretension can simultaneously It is used for support meanss, this device applies recuperability, especially in the form of flexible member, rubber element, elastomer etc..Support It is clamped in after the circumference locating snap ring of male component in the flexible member on element or shading ring, and therefore to intercalation part The direction of insertion of part applies above-mentioned axial compressive force.As a result, male component can be extruded in its leading section, i.e. with stop Its relative end of ring, applies compression stress by flexible member on this locating snap ring, is excessively inserting the line in space against restriction Inwall in the attachment means of road is so that the leading section of male component there stops moving.By this way, in male component What leading section provided is excessively inserting space and can be usually reduced as much as possible, or male component can for good and all extend wherein, only Flexible member is wanted to act on male component.As a result, it is possible to be that only a small amount of medium can be retained in intercalation part In the remainder being excessively inserting space of the front end of part.Be retained in medium therein therefore only can apply this little Compression stress is to male component so that being particularly due to the counter-pressure being produced by the flexible member of there it is not necessary that or several Any necessary worry result is not had to be to extrude male component from coupling.

Additionally, the device of applying recuperability or restoring means can include at least two and have the spring bullet being placed in therebetween The retaining ring of property element, this retaining ring is arranged in a part for male component, especially in circumferential groove or have the straight of reduction The male component in footpath partly in.It is arranged in the retaining ring in the direction of the retaining element of coupling and couple thus can be supported on Partly go up, and another retaining ring on male component is supported on respect on the jut of coupling.By two Flexible member is inserted, elastic pressure can be applied in the retaining ring being axially supported on male component between individual retaining ring. After being excessively inserting male component, the retaining ring being upwardly oriented in the side of the retaining element of coupling is locked in coupling On.Flexible member can produce reaction force to resist the ice pressure forming medium icicle, thus it is extruded, result intercalation part Part is not extruded the inside of coupling.Due to the reduction of ice pressure, the recuperability of flexible member is entered towards extrusion pin part One stepping enters to be excessively inserting in space (that is, being moved axially in direction of insertion) and acts on.

Verified it is further advantageous that by the pass through openings being arranged in male component (through opening) shape Become tapered to be tapered.As a result, even if under the frozen state of medium, compression stress is preferably applied to the insertion of male component On direction, i.e. on the direction of the leading section of male component, because due to the clear span of the pass through openings of male component or internal diameter Increase minimizing, by the icicle growing on the direction of the leading section of male component to its applying power.Therefore it is excessively inserting sky Between can be reduced, because male component is pressed into wherein.Therefore, in being excessively inserting space, hardly assemble any possible change Obtain problematic ice.

In order to keep being excessively inserting, space is as little as possible, even if being produced by inner chamber when contrary with the direction of insertion of male component During raw counter-pressure, in addition to the conical by its shape of the internal run-through opening of male component, can additionally provide in direction of insertion Extrusion pin part gos deep into the flexible member of the description before within connecting device for line.Therefore, flexible member supports by insertion The extrusion pin part that the conical by its shape of opening causes enters coupling.For example, it is possible to for clear span come to determine tapered by The size of the thin internal run-through opening of gradual change is so that the clear span on the leading section of male component is 1.5+/- 0.05mm and plug Clear span on the opposed end of part is 2+/- 0.05mm.

Measure as further, the inner chamber of this connecting device for line can have approximately suitable at least in a part Insertion in (one or more) media lines and/or male component that connect to or can be connected to connecting device for line is opened The clear span of the clear span at the outlet ends of mouth.Therefore, flow through for medium so that this flowing is from media lines to another One media lines or can be less than former diameter to the inner chamber of inside of connecting device for line of assembly, especially Only can have the internal run-through opening identical clear span with media lines and male component.Especially, therefore close at its end At least respective portion of the inner chamber of media lines to connecting device for line or male component or inner chamber is connected at end Point can have a clear span of 1.5 to 3mm, preferably 2mm, herein with media lines or its male component and its internal run-through The respective part chamber of register can mix mutually in the inside of connecting device for line.In the cross section in part chamber, Chamber can have the bigger clear span obtaining as the geometry in transverse portions chamber.

It is furthermore possible to also provide at least one sealing device is used for preventing medium osmosis entrance to be excessively inserting at least the one of space Individual partly in.As a result, so it is excessively inserting space not being reduced, but prevent medium osmosis to enter and be excessively inserting space So that medium there can not be assembled, medium may freeze when the temperature of medium is down to below its solidification point in a part Knot, can apply ice pressure on male component.This sealing device can be arranged in, for example, the leading section area of male component In domain, herein the leading section of male component or the forward part of male component can have herein with male component other Main body compares the external diameter of reduction so that potted component can add there.In this case, potted component can be supported on On the outside of the circumferential inner wall of the coupling of connecting device for line, therefore prevent the medium being excessively inserting space from front portion from entering Enter radial arrange around male component and be sealed by packaging axially limit be excessively inserting space, to prevent medium from line Any leakage of the coupling in the inside of road attachment means.Additionally, sealing device can be disposed in away from male component In the circumferential groove of the male component of leading section, herein, the front end portion of male component has ratio and adds to potted component The bigger external diameter of part.In such manner, it is possible to prevent any medium from male component on the direction of the other end of male component Leading section is passed through, i.e. be excessively inserting in space in second laterally arranging around male component.If potted component is arranged On the front end region of male component, the front end region of therefore male component has reduction compared with the main body of male component Diameter, and be added to there, it can be sized so that it is alignd with the leading section of male component.Can also be really Determine the size of potted component and form it into so that it is still in the wall limiting the connecting device for line being excessively inserting space On.As a result, reduced by the wall thickness of the circumferential wall of potted component and flow through path so that only less space is available, Its medium can not be assembled, and condensed medium can apply ice pressure.

Prove further advantageously be clamped in the locating snap ring of male component above and or below at least one is close The form of envelope element, especially in the form of o-ring and/or type ring (form ring), configures sealing device.As a result, a side Face, can with respect to the inwall of the coupling of connecting device for line around the locating snap ring of male component Zone Full to plug Part is sealed.During being excessively inserting of potted component or element, especially o-ring and/or type ring can be by flexibly Deformation, and during the second locating snap ring of especially male component removes pressure after the retaining element of coupling, Easily rebound again, i.e. be back to its original-shape or stress reduction position at least in part.As with the shape of potted component Formula or with around male component outside and receive coupling in opening female connector part wall inner side between Male component be arranged in outside on the potted component of at least one form this device as a result, it is possible to prevent medium from oozing Enter being excessively inserting in space around male component because potted component be disposed in this be excessively inserting in space and close to it Envelope is entered with preventing medium.Especially, potted component can be disposed in and be excessively inserting in space so that when male component is inserted into When in coupling, they are compressed, but after locking the second locating snap ring on the retaining element of coupling, they are at least Partly be released pressure, thus surround in the upper and lower side of the first locating snap ring its simultaneously seal be excessively inserting space prevent any Medium enters.

This at least one sealing device is advantageously supported in the inside of coupling and/or is kept with Anti-extrusion (falling out), especially by end bushing.By means of this end bushing, can prop up in the inside of coupling Support this at least one sealing device.End bushing itself can be supported on ratchet or other devices in the inside of coupling On.However, under ice pressure, there is ratchet by the risk being broken off.Due to freezing compared with the non-frozen state of medium or The Volume Changes of the medium freezing, so occur in that ice pressure or ice pressure.As a result, pressure area increases, and this thus leads to coupling What socket part was divided couples the more high load capacity of circle.In order to avoid ratchet any shearing and alleviate couple circle pressure it is advantageous that In the way of firm connection, end bushing is connected to coupling.For example, it is possible to by laser welding, friction or ultrasonic bond Connect or bond the connection that strong bonded is provided.Due to the connection of end bushing and the strong bonded of coupling, produce now The distribution of ice pressure, thus the ice pressure applying male component to connecting device for line during the ice of medium is formed is passed It is handed to and couples circle, and apply to act on to the ice pressure of sealing device and end bushing and be fastened on coupling in the way of firm connection Socket part divide in end bushing on.Connection due to coupling and the strong bonded of end bushing, it is possible to achieve coupling In male component higher confining force.For example, the connection of strong bonded can be formed as the weld seam of segmentation or be formed as Circumference, i.e. the weld seam of not segmentation.Advantageously, end bushing is made up of in order to be able to without problems the material of impermeable laser It is laser welded to coupling.Additionally, at least coupling can be made up of the material of saturating laser, especially connecting device for line Or whole coupling access components that male component (one or more) can be inserted into can be made up of plastics, the material of particularly saturating laser Material.Due to the connection of end bushing and the strong bonded of coupling, possible confining force is higher or is likely to be simply equal to Couple the confining force of circle.

It is further advantageous that male component can at least substantially be closed on end side or be closed, and have to The exit opening of a few side, its internal run-through open fluid communication with male component.Due to providing this side Exit opening or the exit opening of at least one this side, are outwardly into circuit when medium spills from the inside of male component During the inner chamber of attachment means, medium is deflected.As a result, freezing medium or medium icicle can not arbitrarily penetrate into connection In this separation between the male component of device and coupling, and by mistake lead to separate and plug due to applying pressure The connection of part.On the contrary, freezing medium prevents so, because the so initial off exit opening of side, and therefore Prevent any medium from leaking in the inner chamber in the coupling of connecting device for line, because larger those of less volume ratio Quickly freeze.

If the internal diameter of the exit opening of at least one side or the outlet of side are opened on the leading section of male component The summation of the internal diameter of mouth is less than or equal to the clear span of internal run-through opening, then prove especially advantageous with regard to this point.Especially It is that the internal diameter of the exit opening of at least one side can be less than 2mm.For example, for the size of the male component of 4 × 1mm, The internal run-through opening of male component has the diameter of 2mm.The size of 5 × 1mm, generally also in automotive field, gives 3mm Male component internal run-through opening diameter.In commercial car field, the size of 6 × 1mm or 8 × 1mm is very common Size, result is that internal run-through opening is measured as 4mm or 6mm.It is preferred that the internal diameter of the exit opening of side or net The internal diameter of the pass through openings in the wide front end region less than male component.Armed with the exit opening of multiple sides, then Its diameter can change, and for example, the exit opening of side relative to each other can have identical diameter, and it offsets with from these The exit opening of the side of arrangement is different.Due to select side exit opening internal diameter, it is possible to use flow media realize with The relevant throttling of flowing.Knot so can be had by this throttling or volume reduction of the exit opening of offer side Really, that is, the medium being present in the male component such as exit opening of the side of SAE male component freezes first, and And be pushed out thus forming icicle from connecting device for line.For example, in this case, than male component as previously described The pass through openings of tapered shape can have supporting role, because its diameter increases so that icicle in the direction of media lines Can easily be released further from male component in this direction again.

On the outside of male component, in the region of the exit point of the exit opening of at least one side, male component can It is configured to flat.In like fashion, it is possible to achieve the reduction of the pressure loss of flow media.Advantageously, shape during flattening The edge becoming is circular or flat, or has inclined-plane in order to avoid the damage of potted component, and this potted component is another Other places is added to male component to be sealed against inside the coupling of connecting device for line.

The exit opening of at least one side the longitudinal direction of the internal run-through opening with male component can prolong at right corner degree Stretch substantially aligned.It is also possible that becoming certain angle with the longitudinal axis of internal run-through opening of male component or the longitudinal axis of male component The exit opening of at least one side is arranged at degree especially obtuse angle, and the pressure loss relevant with flow media whereby can It is reduced and as the measurement of preventative cavitation.In addition, the exit opening of side can be from the internal run-through opening of male component Linear extension and/or bending to outside it.

In addition to the complete end side closure of the internal run-through opening of male component, this leading section of male component with internal Pass through openings are relevant can be configured to open.In order to remain able to close the inside of male component in the case of freezing medium The leading section of pass through openings, i.e. there is the formation of medium icicle, at least one closing feature can be disposed in inside, i.e. Internal run-through open interior.In this case, male component can have connection to internal run-through opening on leading flank Exit opening and at least one closing feature being arranged in internal run-through open interior, this closing feature is configured to pass medium Icicle may move and has spring, and provides this closing feature to form medium ice in pass through openings internally The front exit opening of male component is closed during post.Closing feature can be moved by forming medium icicle.It is used for substantially Fully or at least partially end side closes the internal run-through opening of male component or front exit opening.For this purpose, There is the direction quilt of the leading section in male component for the internal run-through open interior in male component for the closing feature forming icicle Push away forward, and enter setting exit opening there, this exit opening can have to be opened with the internal run-through of male component Mouth compares the diameter of reduction, and closing feature is at least partially submerged in this exit opening.Especially closing feature with regard to its shape and/ Or its internal diameter becomes to deform, and the exit opening being therefore arranged on the leading section of male component is partially or completely pass Close.The front exit opening of male component can be with the internal run-through register of male component or be arranged to and male component Internal run-through opening Longitudinal extending angled.

Can prevent medium icicle from oozing in this moveable closing feature of the internal run-through open interior of male component Penetrate into the coupling into connecting device for line.Freezing strength in the region of connecting device for line, especially single medium Conduit and/or the burble point to the tie point of assembly thus being remarkably increased, for example, and in regional traffic instrument water tank Attachment means in identical.The previously described male component can be therefore the attachment means of this vehicles water tank, i.e. It is fixedly placed on vehicles water tank, herein, for example, the coupling access component connecting the connecting device for line of media lines can It is connected to attachment means, for example, by insertion.As a result, create connecting device for line, wherein connecting device for line is independent Part be that the coupling access component of the male component of water tank and connecting device for line can be again by with regard to each other herein Move and connect thus forming plug.Herein it is also possible to be excessively inserting with identical the offer again having been described above before, in order to At the attachment means of water tank, connecting device for line is fastened to coupling.

In order to produce the freezing strength of connecting device for line or improve another possibility is that of connecting device for line In partly going up of male component, at least one volume compensation element with sealing function is arranged on outside.Volume compensation element For acting on the volume compensation at the pressure medium on male component, for example, herein such that it is able to by the pressure that can subscribe The limit energetically produces volume compensation.For example, this pressure limit can be the pressure in 50 Palestine and Israels.In this case, body Long-pending compensating element, can have with regard to its axially extending extendible at least one portion, to produce volume pressure with respect to medium Contract, and result is volume compensation, is back to initial position herein when pressure stops.Advantageously, therefore volume is mended Repay element and show spring.For example, volume compensation element is by elastomer or solid such as metal material and elastomer Group is combined into, and metal material can be embedded in elastomer in this case.For example, volume compensation element is axially extendable Part can be configured to the element of sleeve shaped, and is formed by by the material of spring, this material such as closed pore cellulose rubber Glue, and/or it can be configured to spring, such as, for example, with wavy form.For example, elastomer can be EPDM.

Therefore, volume compensation element can be configured to a part or manifold, for example, two-part.At one In the configuration dividing, the front end portion of volume compensation element can have larger external diameter and/or be configured to convex (protuberance-like) in order to provide maximum possible sealing area, thus system run duration i.e., Medium is made to be capable of with can the sealing of predefined pressure and/or temperature range via the flowing of this leading section.In volume It is provided that sealing ring, such as tetracyclic ring or such as o-ring in the manifold configuration of compensating element, it is in circuit even The run duration of connection device i.e., also creates the sealing with specified pressure when medium current through line attachment means And/or temperature range.For example, this sealing ring can be accommodated between support ring in order to connect in male component or assembly The axial direction of connection device or longitudinal direction keep its position.The region of the burble point between the circuit conveying for fuel Interior and provide this volume compensation element to be especially suitable in SCR (SCR) and cooling water.

In this insertion process, need so-called being excessively inserting in order to promote locating snap ring 60 to fully pass over retaining element 7 Or its part 71.This means that be excessively inserting space 11 is provided at the front portion before the leading section 61 of male component 6 simultaneously In the inside of coupling 10 at place.Other is excessively inserting in the region that space 11a is provided at potted component 8,9, sealing Element 8,9 is circumferentially provided in radially around the inside of the coupling 10 of male component 6, in order to prevent medium From coupling leakage.Potted component 8,9 is not provided, medium be possible to along male component from be excessively inserting space 11 through entering Enter to be excessively inserting space 11a thus leaking.Two sealing rings 8,9 are maintained at by potted component retaining element 80,90 and couple Its position in the inside of part 10.Its all of part 8,9,80,90 together form and packs.

Inner chamber 12 be provided at connecting device for line 1 inside in as the flowing of medium or the flowing road of passage Footpath.This is formed by two part chambeies 12a, 12b, this two part chambeies at point 12c be mixed with each other.12b is very short in part chamber And generally include and be excessively inserting space 11.

This connecting device for line 1 can be provided, for example, stave in a vehicle or underfloor region In.By media lines 2,3 can with pumped (conveying) medium, for example, stoichiometric point in vehicle motor or there and vehicle water tank or Between the pump of person there.Due to dominant different temperature at each point in a vehicle, to the medium there using The durothermic requirement of conduit is different so that the media lines differently designing are connected to each other.This is particularly by circuit Attachment means 1 are completing.In low temperature, according to the medium by media lines 2,3 and connecting device for line 1 conveying, permissible The medium occurring being present in media lines 2,3 and the inner chamber 12 of connecting device for line 1 freezes.This can occur, especially For medium, such as aqueous solution of urea orDuring freezing, because coherent condition is changed into solid-state companion from liquid With volume increase, icicle gradually forms, its mobile inside to conduit system, or especially in the region freezing to occur The place that there is high ice pressure gradually forms further.Therefore, if medium is present in the inner chamber 12 there freezing, Volumetric expansion and related high pressure (ice pressure) can have following result, and male component is contrary with direction of insertion i.e., The direction of arrow P1 is extruded from connecting device for line 1.This is certainly undesirable, and will have in media lines This point the result of leakage occurs, or undesirably additionally from media lines and connecting device for line (one or more) Flow through the medium of conduit system and optional other compositions there leak.This all should be prevented under any circumstance.

For this purpose, in the connecting device for line 1 according to Fig. 2, in the possible jelly of the inside of connecting device for line 1 Knot body is amassed and is reduced.Herein interior section chamber 12a with 12b have compared with the connecting device for line 1 according to Fig. 1 significantly less Clear span d of internal diameter or significantly less_i.Clear span is passed through in particular corresponding to the internal diameter of media lines 2,3 or the inside of male component 6 Open up the clear span of mouth 62.The internal diameter of part chamber 12a, 12b or clear span d_iCan be, for example, therefore 1.5 to 3mm, preferably 2mm. This flow section be enough to guide medium to pass through connecting device for line.Critical zone in connecting device for line 1, herein for inside Chamber 12 can be significantly reduced therefore compared with shown in Fig. 1, and has therefore been significantly reduced by dividing that ice pressure causes The risk being connected with the male component 6 of media lines 2 from connecting device for line 1 or its coupling 10.

Internally reduce in the critical zone in chamber 12 and be excessively inserting space 11 or spring back into its locking in male component 6 After position keep further possibility be conduit system during the operation i.e., when medium flow through there When keep that to be excessively inserting space little as much as possible.This can be realized by various measures, and every kind of measure is all demonstrated by restoring Effect.Show one of possible measure in figures 3 and 4.According to Fig. 3, the internal run-through opening 62 of male component 6 is configured to Tapered tapered.This means in the region of the leading section 61 of male component 6, pass through openings have less than connection extremely Diameter d in the relative second end 63 of media lines 2₂Diameter d₁.For example, diameter d₁Can for 1.5mm+/- 0.05mm simultaneously And diameter d₂Can be 2mm+/- 0.05mm.This taper of internal run-through opening 62 is as the motion internally in the medium freezing The elasticity or spring element of period.Assume that media lines freeze from burble point, i.e. from connecting device for line outwards, and The ice being formed by the medium freezing moves in the direction of connecting device for line from media lines, and basically this is problematic 's.By providing tapered tapered pass through openings, the direction that ice movement can be used for being excessively inserting space 11 is moved Male component.If the medium freezing is moved through the media lines 2 connecting to male component 6, by male component 6 in plug The direction of the leading section 61 of part, i.e. from larger diameter d₂Direction in less diameter d₁Direction, in the side of arrow P2 It is pressed into, male component 6 and be excessively inserting space 11 so that only a small amount of ice is formed at and is excessively inserting in space 11.In the diagram It can be seen that being pressed into the position of the male component 6 being excessively inserting in space 11.The direction of the taper of pass through openings 62 is advantageously joined It is set to and is tapered from the end of male component 6, media lines are in the leading section 61 of male component 6 at this male component 6 Direction is connected or connects to pass through openings 62.For example, it is possible to two cores by using correspondingly shaping complete plug The formation of the tapered tapered pass through openings of components interior.

In embodiment shown in Fig. 4, in addition to the tapered tapered pass through openings 62 of male component 6, Flexible member 100 is provided inside coupling 10, clamps below in the locating snap ring 60 of male component 6.For example, flexible member 100 can be configured in the form of spring element, rubber element, any elastomer or other elasticity or recovery.Bullet Property element 100 be located at male component 6 swedged part 65 is internal or the circumferential groove of male component 6 in.Institute in the diagram In the illustrative embodiments shown, flexible member 100 passes through shading ring or support ring 101 in the end 63 of male component 6 Direction is kept pre-.Flexible member 100 is used for providing recuperability, utilizes its leading section 61 to support plug in order to one side Part 6 is against being limited on the wall 13 being excessively inserting space 11 within connecting device for line 1, and reverse extrusion wall 13 makes It is excessively inserting space 11 little as much as possible, as shown in Figure 4.On the other hand, the recuperability of flexible member 100 is for having to pressure Flexibly provide resistance, for example, it is due to the icicle of freezing medium that gradually forms in chamber 12 so that icicle that this pressure occurs Not or substantially extend into and be excessively inserting in space 11.If before, to as described in Fig. 3, male component is by its front end Portion 61 is pressed through tapered tapered pass through openings 62, and by the compression stress that applied by flexible member 100 so that The wall 13 of its collision connecting device for line 1, medium osmosis entrance is excessively inserting space 11 and obtains strict control.By the party Formula is excessively inserting space 11a it is also possible to avoid medium to possess the second of larger diameter through the outside entrance of male component 6.In Fig. 4 Shown in embodiment in, this is arranged to be excessively inserting space or chamber.The leading section 61 only having male component 6 is excessive Abut against in the region of insertion space 11a on wall 13.However, also or assume alternatively that be excessively inserting space 11a pass through elasticity The effect of element 100 or another flexible member is closed, and therefore flexible member acts on male component 6 in the way of extruding And/or so that flexible member starts on the wall 13a of the coupling 10 there being formed on potted component 8,9.This is in figure It is simplified in optional embodiment in 10 and Figure 20 and illustrate.Figure 10 a shows compressed-bit under operating pressure for the potted component Put, can be 3,5,8 or even 13 bars depending on this operating pressure of system, and potted component especially flexible member 100.? In Figure 10 and 10a, sealing ring 8 is static to be leaned against on the wall 13a of coupling 10.For example, with the shape of spring element or elastomer The offer of formula flexible member 100 there extrudes two sealing rings 8,9, and also extruding is arranged in these with potted component admittedly Determine the potted component retaining element 80 between element 90, potted component retaining element 90 supports sealing ring 9 in the direction of wall 13a, Also support sealing ring 8 and potted component retaining element 80, result is to be excessively inserting space 11a to be minimized.All of element 8, 9th, 80,90 contact with male component 6 or communicate.Because flexible member 100 is configured to springy or can reset, and And therefore to be capable of resetting with compression identical mode, male component 6 can be easily excessively inserting, in order to subsequent It is locked in the desired locations in the inside of coupling 10.Due to the effect of elastomer 100 springy, but male component with It is maintained at the low position within coupling 10 afterwards, be excessively inserting space 11 in order to reduce.Additionally or alternatively, it is The outside of male component within coupling 10 seals the effect in flexible member 100 of the sealing ring providing or potted component Under be extruded, travel further into that coupling 10 is internal to be minimized so that being excessively inserting space 11a.

In the embodiment of connecting device for line 1 with coupling 10 and male component 6 shown in Figure 20, replace Potted component retaining element 90, provides the retaining element 91 of moveable ring or sleeve shaped inside coupling 10.Its There is the flange portion 92 of the circumference of the inside protruding into coupling 10.It is used for limiting may move in coupling 10 Ring or sleeve shaped retaining element 91 movement.For this purpose, flange portion 92 can with inside coupling 10 The stopping edge 14 being formed cooperates.Flexible member 100 in the form of spring element is supported on moveable ring or sleeve End on the retaining element 91 of shape, or more accurately in the flange of the retaining element 91 of moveable ring or sleeve shaped In part 92, relative with flange portion 92 possible contact zone 93, there is the fixation stopping edge 14 using flange portion 92 Element 91 position shown in fig. 20 can be contacted with possible contact zone 93 or be in contact with it.Using its opposed end, The flexible member 100 of spring element form is supported on end bushing 94, and this end bushing 94 also is disposed on coupling 10 Internal.End bushing 94 is supported on inside coupling 10 on ratchet 95, and this ratchet 95 protrudes into coupling 10 Inside, also shows as in Figure 20.In fig. 20 in shown embodiment, at least it is excessively inserting position when male component 6 is located at When putting (as shown in Figure 20), the circumference locating snap ring 60 of male component 6 stops on the side of end bushing 94, and with spring element The flexible member 100 of the form of part is relatively.

In the diagram in shown illustrative embodiments, two ways cooperation is to insert coupling 11 in male component 6 In after reduce and be excessively inserting space 11, that is, tapered tapered internal run-through opening 62, because internal ice moves Move it and male component 6 is extruded as coupling 10, i.e. in the direction of arrow P2.Additionally, by the effect of flexible member 100 It is excessively inserting space 11 or 11a is reduced, herein when ice is formed from the direction of inner chamber 12 or 12a and is squeezed into Be excessively inserting in space 11 thus as much as possible reduce be excessively inserting space 11 and thus reduce marginal space when, flexible member 100 also have supporting role, because freezing medium will form ice in this marginal space.Forming ice under such pressure can not Enough re-form so that this pressure is from coupling 10 extrusion pin part 6.

In embodiment shown in Fig. 5 and 5a, it is not only the internal diameter in chamber 12 within connecting device for line 1 or net Width is strictly reduced, identical with the embodiment according to Fig. 2, and has additionally provided elastic device 110, and it includes Two retaining rings 111,112, flexible member 113 is mediate.Flexible member is kept ring 111,112 two ends and is placed in Side.Whole elastic device 110 is disposed in the part in the outer circle circumferential grooves 66 of male component 6 or in male component 6 In, this part has the diameter of reduction compared with the remaining main body of male component 6.On coupling 10, retaining ring 111 is propped up In the interior section 71 of retaining element 7, retaining ring 112 is supported on male component 6 simultaneously for support, and optionally also close On envelope element retaining element 90.Therefore, for locking male component 6 or being excessively inserting of retaining ring 111 on retaining element 7 It is easily possible (dotted line position of the male component 6 in Fig. 5 a).Male component 6 position in operational state, i.e. It has been shown in solid lines latched position in Fig. 5 a.Due to flexible member 113, after being excessively inserting of male component 6, male component 6 are maintained at and are excessively inserting position so that being excessively inserting space 11 and being optionally also excessively inserting space 11a and can be kept Little as much as possible.
