Technical field

The present invention relates to a kind of be used for connecting an out-put container and a target container, be particularly useful for coupling assembling in the self-propelled vehicle fueling.

Background technology

This coupling assembling allow to target container inject a kind of medium, as a kind of fluid or short grained discrete material.In the case, out-put container is connected by coupling assembling each other in this wise with target container, makes that the loss of medium part is as far as possible little.Particularly the fuel of self-propelled vehicle especially can be injected in the target container that is installed in the self-propelled vehicle from a portable little out-put container for the additive that reaches the few burning of objectionable impurities.At this, a kind of simple possibility is by the fixedly connection of flexible pipe of both sides.The shortcoming of this mode is: decide on out-put container and out-put container position to each other, connect the loss that can cause a part of medium when separating when out-put container is opened or at flexible pipe.This is imperfect under medium costliness or for example deletrious situation especially.

For medium is injected target container, also can use a funnel as out-put container.On the extension running-on section that is fixed to target container, this funnel has the discharge section of an outside thread or a tubulose usually as coupling assembling, and this discharge section can be inserted in the extension running-on section of target container.The shortcoming of this mode is: for the left situation in funnel of medium, may leak at funnel this medium when target container separates, because remaining media can flow out and target container may overflow on the other hand from funnel on the one hand.

Summary of the invention

Task of the present invention is, a kind of coupling assembling is provided, and this coupling assembling does not make medium import to the target container from out-put container with can having relative permitivity.

According to the present invention, this task will realize by a kind of coupling assembling that is used to connect an out-put container and a target container, wherein, this coupling assembling have one discharge cylinder (this discharges cylinder have one unlimited and can with out-put container bonded assembly first end face and an osed top the second end and at least one discharge orifice in a circumferential surface) and the control cylinder of this discharge cylinder of encirclement in the zone of discharge orifice, wherein, in a control position, (be connected with target container) at coupling assembling described in this control position, this discharge cylinder and control cylinder can constitute between an off position and an open position with relatively moving, the discharge orifice of cylinder is discharged in the control cylinder sealing in described off position, and control cylinder discharges the discharge orifice of discharging cylinder in described open position.

Out-put container and target container are used for receiver media, for example especially liquid and granule or loose material.Inject for the first time to target container, filling or metaideophone and for the time at target container mixed multi-component medium, can according to circumstances out-put container be connected with target container by coupling assembling.Aspect the present invention, for example be interpreted as case, jar or be used to continue the pipe or the flexible pipe of boot media for target container.In addition, also can consider funnel as out-put container.Decide on form of implementation of the present invention, the extension running-on section on the target container can be the extension running-on section of a simple opening or a complexity, as has the part of an externally threaded pipeline section or a bayonet fittings.Discharge first end face that cylinder also can open wide and at least one opening is set in the zone of first end face, this opening can be connected with out-put container.

The discharge cylinder of this coupling assembling is a hollow cylinder, and it is connected in this wise with out-put container, makes the medium of out-put container can flow into the discharge cylinder by first end face that opens wide.But in the off position of control cylinder, discharge cylinder to outer closure, make medium to flow out.Described at least one discharge orifice that is positioned on its circumferential surface seals by the control cylinder that also is configured to hollow cylinder.For this purpose, discharge cylinder and control cylinder and constituted in this wise, make control cylinder at least in the zone of discharge orifice with its inside face by touch on the outside face of discharging cylinder and/or described discharge orifice by the sealing arrangement that adds such as sealing lip quilt to outer closure.Discharge cylinder and control cylinder and preferably respectively have circular cross-sectional plane.But other cross-sectional plane, for example polygonal cross-sectional plane also is satisfactory.Control cylinder needn't surround the discharge cylinder fully, and can for example slot in the vertical.

Control cylinder and discharge cylinder and can so relatively move along a spindle axis, make the discharge orifice of discharging cylinder coupling assembling with can be opened after target container is connected and can flow into the target container by the discharge cylinder from out-put container in this open position medium.After filling finished, control cylinder relatively moved again with discharging cylinder so that discharge orifice again the Be Controlled potting close.Out-put container and out-put container are separated, and can not cause the loss of left medium in out-put container or discharge cylinder.

Described at least one discharge orifice is adapting to specific medium and required input speed aspect its size.In addition, input speed also can be controlled relative to discharging the degree that cylinder moves by control cylinder.

Coupling assembling both can be connected integratedly with out-put container and also can be set to independently and constantly or temporarily be fixed on the out-put container.Under the situation of coupling assembling independently, be fixed on the out-put container by grafting joint, screw connection or a bayonet fittings and meet the requirements.Also can use back springing type to connect (Aufprellverbindung) in addition.For coupling assembling is connected with target container, grafting joint, screw connection or bayonet fittings especially meet the requirements.What not only meet the requirements in the out-put container side but also in the target container side is that sealing arrangement is set, so that stop medium by mistake to flow out effectively.

In a further configuration of the present invention, control cylinder extension running-on fragment position of relative target container in control position is provided with regularly.

In this further configuration, in control position, discharge cylinder and move relative to target container and control cylinder, wherein, the relative target container of this control cylinder position is maintained fixed.Can realize especially simple configuration thus, because N/R is in the case: be positioned at in-to-in and discharge cylinder and must be bearing on the extension running-on section of target container in that side that is positioned at exterior control cylinder and pass control cylinder thus or act on the target container around this control cylinder.And discharge cylinder and control cylinder are sealed mutually.

In a further configuration of the present invention, described at least one discharge orifice is arranged in this wise, makes this discharge orifice reach the inside that is positioned at target container in control cylinder and discharge cylinder open position to each other in the control position of coupling assembling.

Thus, when separating with target container, coupling assembling can not cause the outflow that is not intended to of medium.After the relative control cylinder of discharge cylinder moves to off position, out-put container can be taken off from target container with coupling assembling, thus, the medium part that no longer flow in the target container can not leaked and discharge cylinder the liquid level the target container is descended by taking off in case of necessity from out-put container.

In a further configuration, control cylinder applies power with the discharge cylinder each other by an elastic force towards the directive effect of off position.

In this form of implementation, coupling assembling for example can be transferred to open position by manually applying a power opposite with elastic force.In case this power disappears, coupling assembling will turn back in the off position by springs preload power.Can reduce the danger that coupling assembling is by mistake deviate from from target container thus in open position.In addition, when discharging cylinder and control cylinder needn't manually be withdrawn in the off position with the end MEDIA FLOW time, also can simplify the injection of deciding dosage of target container.

In a further configuration of the present invention, coupling assembling is provided with at least one retaining pawl, in the stop position of this retaining pawl, can stop control cylinder to discharge the mobility of cylinder relatively by this retaining pawl.

In this stop position, discharging cylinder and relatively moving of control cylinder is impossible or only removable such degree, does not have medium and flow out by discharge orifice from discharging cylinder on this degree.Can guarantee can not cause discharge orifice by mistake to open thus.For this reason, retaining pawl has produced sealed being connected of preferred shape of discharging between cylinder and the control cylinder.In the case, this retaining pawl can be constituted in this wise, makes it directly manually to be moved in stop position or the releasing position, or also can be operated in the following manner indirectly that promptly coupling assembling is presented in the control position.

In a further configuration of the present invention, described at least one retaining pawl is constituted in this wise, makes to make this retaining pawl move to the releasing position by off position by the extension running-on Duan Shangke that coupling assembling is installed to target container.

In this further configuration, the extension running-on section by coupling assembling and target container be connected the operation that causes retaining pawl.Just make retaining pawl import the releasing position thus, in this releasing position, discharge cylinder and the control cylinder open position that can relatively move each other.Therefore this open position can not by mistake produce before the control position that reaches coupling assembling on the extension running-on section of target container.Retaining pawl both can be realized by extending the direct or indirect effect of running-on section to the motion of releasing position, component part that also can be by coupling assembling manually operated relative motion to each other realizes, for example the rotation of the collar of the bayonet fittings by coupling assembling realizes.

In a further configuration of the present invention, described at least one retaining pawl is set between control cylinder and the outer sleeve, wherein, this outer sleeve makes retaining pawl deflect into a releasing position from a stop position for the extension running-on Duan Shangke that is fixed to target container moves in this wise relative to control cylinder.

In such form of implementation, control cylinder and outer sleeve can relatively move on an installation direction.Coupling assembling is being installed to, especially is being screwed on the extension running-on section of target container, in case these parts to one (preferred control cylinder) when touching on the boss of extension running-on section side, these two parts can relatively move.Then, relative motion that in outer sleeve continues motion process, occur, between control cylinder and the outer sleeve will cause described at least one be located at the deflection of the retaining pawl between control cylinder and the outer sleeve, this retaining pawl deflects into the rollover states of a release by a previous stop rollover states thus and allows to discharge relative motion between cylinder and the control cylinder thus.The reliability of height can realized and provide to this configuration simply, because needn't worry moving unintentionally of control cylinder and outer sleeve.Particularly advantageous is such configuration: wherein control cylinder is difficult to manually approaching in the not installing condition of coupling assembling or is provided with an additional spring between outer sleeve and control cylinder, and this spring has suppressed to relatively move unintentionally.Retaining pawl for example can be configured to T shape, and wherein, the moving of one of exterior end that be positioned at that flip-flop movement then can described T shape realized.

In a further configuration of the present invention, described at least one retaining pawl is configured to L shaped and has a stop leg and an operation leg, wherein, the nearly middle-end of this operation leg be bearing on the swing step of control cylinder and the distal end of operation leg in the releasing position by touching on the operation step of outer sleeve.

This retaining pawl is a kind of simple especially configuration.In stop position, the stop leg preferably extends discharging on the direction that cylinder and control cylinder relatively move.In the case, the stop leg with its distal end by touch discharge on the boss face of cylinder and with it nearly middle-end by touching on the swing step at control cylinder.This stop leg stops the relative motion of discharging between cylinder and the control cylinder to reach to stop thus can reach open position.When outer sleeve when control cylinder moves, this outer sleeve is caught the distal end of operation leg with its operation step, make that this operation leg also makes and the outwards swing in the zone of the boss face of discharging cylinder of this operation leg bonded assembly stop integratedly leg thus around the swing step upset of control cylinder in the process that this outer sleeve continues to move.Reach the releasing position thus, in this releasing position, discharge cylinder and can move relative to control cylinder.

In a further configuration of the present invention, described at least one retaining pawl is loaded by the direction of an elastic force towards stop position.

Thus, for example after coupling assembling was removed from the extension running-on section of target container, retaining pawl can automatically turn back in the stop position.Can cancel thus and make retaining pawl move to manual movement in its stop position.

In a further configuration of the present invention, coupling assembling is provided with at least two retaining pawls that are arranged on the control cylinder excircle, and these retaining pawls are connected to each other by along the circumferential direction directed elastomeric centre part.

Particularly advantageous in the case is to have four or a plurality of preferably configuration of the even retaining pawls of arranging on the circumference of control cylinder.Thus, these a plurality of retaining pawls can reach especially reliably and stop the relative motion of discharging cylinder and control cylinder equably.These retaining pawls can at any time be pressed on the stop position direction by an elastic force by elastomeric centre part, and need not the high structure of cost on the structure of elastomeric element independently is being set between each retaining pawl and control cylinder or the outer sleeve.But these elastomeric centre parts for example are made of the band or the coil spring of elastic stretch.

In a further configuration of the present invention, these retaining pawls jointly are made of integratedly plastics and centre part is configured to elastomeric plastics bridgeware.

But this has embodied on the cost advantageous particularly and has installed the configuration of simple operations.At this, the Plastic Parts of one comprises a plurality of retaining pawls, and these retaining pawls are connected to each other to the whole circle of being made up of retaining pawl and connecting bridge fitting by integrated plastics bridgeware.The plastics bridgeware is being designed aspect its cross-sectional plane and the material behavior thereof like this, makes to put in order circle degree ground elastic stretch like this, makes all retaining pawls outwards to be pressed onto its releasing position from its stop position separately simultaneously.

In further configuration of the present invention, on the stop ring of an annular, be provided with at least two retaining pawls, wherein, this stop ring has an annular disk and some retaining pawl projectioies perpendicular to this annular disk layout.

In this way, can a plurality of retaining pawls be set by unique parts in coupling assembling.At this, that these retaining pawls for example are configured straight strip and play the projection of extending straight up by the inner periphery of annular disk.In the case, can carry out the operation of retaining pawl in the following manner, i.e. the excircle deflection of this annular disk.On the contrary, the inner periphery of this annular disk then is maintained fixed, and feasible elastic deformation with annular disk makes the end motion away from this annular disk of retaining pawl relatively, and for example outwards motion is so that make the coupling assembling release.

In further configuration of the present invention, described annular disk and retaining pawl projection are made of elastomeric material, especially plastics integratedly.

The Construction integration of annular disk and retaining pawl projection allows described annular stop ring to do advantageously to be manufactured to injection-moulding plastic spare on the cost in enormous quantities.In the case, the resilient annular disk in the described ground of section is at least born to make each retaining pawl projection function connected to one another and also allow and is made the deflection of retaining pawl projection by its elastic deformation.Simultaneously, by using elastomeric annular disk that the retaining pawl projection is preloaded in the position, in for example stop position.

Fig. 1 a to 1c illustrates first embodiment and a medium out-put container 80 and dielectric object container 70 of coupling assembling of the present invention.This coupling assembling has 30, one control cylinders 50 of a discharge cylinder and can discharge on cylinder at this from the bottom sleeve.

Discharging cylinder 30 is configured to have the hollow cylinder of circular cross section and has a tubular housing section 32.Its upper surface 34 constitutes unlimitedly and has a negative thread 36, and discharging cylinder 30 can be connected with medium out-put container 80 by this negative thread, and this medium out-put container has the outside thread 82 adaptive with described negative thread 36.The lower surface 38 of discharging cylinder 30 is closed.Be provided with four delivery ports 40 in shell section 32 on the bottom altogether, these delivery ports pass this shell section 32.

Control cylinder 50 is configured to have the hollow cylinder of circular cross section equally.The internal diameter of this control cylinder 50 in the close session 52 of a bottom roughly corresponding to the external diameter of the shell section 32 of discharging cylinder 30, wherein used narrow free-running fit, make to have discharged cylinder 30 and control cylinder 50 and can be relative to each other relatively move along the direction of its spindle axis 90 separately.Above close session 52, be provided with one outer ring around flange segments 54, one that is used to be bearing in target container 70 is extended running-on section 72.On flange segments 54, connecting six dead bolts 56 altogether up, they be locked in of discharging cylinder 30 around secure bridge fitting 42 on.To discharge cylinder 30 and control cylinder 50 detachable and can interconnect by these secure bridge fittings 42 and dead bolt 56 with relatively moving.

Fig. 1 a is illustrated in and arrives control position coupling assembling in the past.This coupling assembling of being made up of discharge cylinder 30 and control cylinder 50 is connected with described out-put container 80.Control cylinder 50 is discharged cylinder 30 relatively in an off position, and in this off position, described close session 52 reaches the top of discharge orifice 40 and closes these discharge orifices thus.

Fig. 1 b represents to be in the coupling assembling in the control position.In this control position this coupling assembling with out-put container by sleeve on the extension running-on section 72 of target container 70.Control cylinder 50 is discharged cylinder 30 relatively and is not in the off position with changing.

From this off position, out-put container 80 moves down with the discharge cylinder 30 of coupling assembling, reaches the open position shown in Fig. 1 c always.In this open position, discharge orifice 40 be positioned at control cylinder 50 lower edge the below and exposed thus.Therefore but the moving path 92 of the medium longshore current in out-put container 80 is passed and is discharged cylinder 30 and flow in the target container 70.

Particularly advantageously be, when with coupling assembling when target container 70 is pulled out at control cylinder 50 and extend the antagonistic force that causes by friction drag on the contact surface between the running-on section 72 greater than the antagonistic force between control cylinder 50 and the discharge cylinder 30.Can realize that thus one upwards affacts the pullout forces of discharging on the cylinder 30 and at first causes: before control cylinder 50 and extension running-on section 72 are thrown off, discharge cylinder 30 and carry out the transition to off position again with control cylinder 50.Can cancel targetedly thus coupling assembling is transferred to off position.

Described first form of implementation of coupling assembling of the present invention allows target container 70 chargings, and can not lose medium.Even when out-put container 80 does not have emptying after the charging process finishes, by taking off out-put container 80 from target container 70 and coupling assembling was closed the leakage that coupling assembling can prevent medium in the past.

Fig. 2 a to 2c illustrates second form of implementation of coupling assembling of the present invention.As in first form of implementation as shown in Fig. 1 a to 1c, this second form of implementation also has one and discharges cylinder 130, and this discharge cylinder has end face 134 and bottom osed top end face 138 of a tubular housing section 132 (this shell section has four discharge orifices of wearing thoroughly 140 on the bottom), an opened upper end.Be provided with in the outside of shell section 132 one around secure bridge fitting 142 and one around locked groove 144.Different with first form of implementation of Fig. 1 a to 1c is to discharge cylinder 130 and be connected integratedly with out-put container 180.

A control cylinder 150 is discharged on the cylinder 130 at this from the bottom sleeve.This control cylinder 150 has the close session 152 of a tubulose, and the external diameter of the internal diameter of this close session and described shell section 132 constitutes a narrow free-running fit.Control cylinder 150 is provided with six dead bolts 156 above close session 152, control cylinder 50 by these dead bolts detachable and can be fixed on with relatively moving discharge cylinder 130 around secure bridge fitting 142 on.Control cylinder 150 has a locking section 154 that diameter is bigger in the upper end of close session 152, be configured with one and have annular receiving slit 157 negative thread 158, that open wide downwards in this locking section, this negative thread is used to make coupling assembling to be fixed on the extension running-on section 172 of target container 170.Altogether four intersected with each other on the trench bottom of receiving slit 157 by the inboard extended dead slot 159 of control cylinder diametrically, be used to receive stop pin 160.

Respectively insert a stop pin 160 in these dead slots 159, this stop pin has a breach that has the lozenges 162 of bent angle at its downside.These stop pins 160 can radially move in acceptance division 159, have wherein inserted a stop pin spring 164 on the outer end of acceptance division 159 respectively, and this spring loads stop pin 160 with a spring force that radially inwardly acts on.

Inserted a coil spring 146 discharging between cylinder 130 and the control cylinder 150, by this coil spring, discharge cylinder 130 relative control cylinders 150 be loaded one make progress on the direction of off position spring force and be pre-loaded in the off position thus.

Fig. 2 a be illustrated in before the control position on the extension running-on section 172 that arrives target container 170, with out-put container 180 bonded assembly coupling assembling integratedly.In this state, during control cylinder 150 and discharge cylinder 130 were in the closed position relative to each other, the close session 152 of control cylinder 150 was positioned on the discharge orifice 140 of discharging cylinder 130 in this off position, made to have stoped the leakage of medium from out-put container 130.Before the control position that reaches Fig. 2 a, discharge can not relatively moving of cylinder 130 and control cylinder 150, in this lock position because stop pin 160 stretches in the locked groove 144 of discharging cylinder 130.

From the state of Fig. 2 a, coupling assembling is screwed around on the target container 170 by the outside thread 174 on negative thread 158 and the extension running-on section 172 with out-put container 130.When screwing, the upper limb that extends running-on section 172 be pressed on the lozenges 162 of stop pin 160 and spring force of making its opposing stop pin spring 164 thus to external pressure.Thus, stop pin 160 arrives in the releasing position shown in Fig. 2 b, and it is extruded from the locked groove 144 of discharging cylinder 130 in this releasing position.

In this control position of coupling assembling, can be pressed onto in the open position of Fig. 2 c discharging the off position of cylinder 130 by Fig. 2 a and 2b.For this purpose, discharge cylinder 130 with out-put container 180 by against the spring force of coil spring 146 to pressing down, make discharge orifice 140 from the zone of the close session 152 of control cylinder 150, shift out.When reaching the state of Fig. 2 b, the medium that is arranged in out-put container 180 can pass the moving path 192 of discharge cylinder 130 longshore currents and flow to target container 170.

No longer be pressed downward with out-put container 180 in case discharge cylinder 130, they will move up based on the spring force of coil spring 146 so, make that the relative control cylinder 150 of discharge cylinder moves in the off position again and the mobile of medium is interrupted.In case control cylinder 150 is screwed by the extension running-on section 172 from target container 170 again, then stop pin 160 is pressed into again in the locked groove 144 by stop pin spring 164, makes that this off position no longer can be left beyond the control position of coupling assembling.

This second form of implementation of Fig. 2 a to 2c is because stop pin is special failure-free, because these stop pins only just allow to carry out the transition to open position in control position and allow medium to flow out thus.

Fig. 3 a to 3c illustrates the 3rd form of implementation of coupling assembling of the present invention.

In the 3rd form of implementation, coupling assembling has one and discharges parts 210, and these discharge parts comprise the sleeve segment 220 and the discharge cylinder 230 of captiveing joint with this sleeve segment that are used for fixing on the out-put container.In addition, this coupling assembling has a control cylinder 250, seven retaining pawls 260 connected to one another and outer sleeves 267.

Discharge cylinder 230 and have a tubular housing section 232, the bottom of this shell section is worn thoroughly by two discharge orifices 240.The upper surface of discharging cylinder 230 is opened wide and is discharged cylinder 230 permission medium free-flowing in discharge cylinder 230 when being connected with out-put container when this.The lower surface 238 that is positioned at the opposite is closed.

Control cylinder 250 is enclosed within on the discharge cylinder 230 from below and has the close session 252 of a bottom, and the internal diameter of this close session constitutes a narrow free-running fit with the external diameter of discharging cylinder 230 and this close session covers these discharge orifices 240 in the off position of Fig. 3 a and 3b.Control cylinder above close session 252, have one around flange segments 254, this flange segments is bearing in control position on the extension running-on section of a target container.The upside of this flange segments be provided with one around swing step 257.

An outer sleeve 267 is enclosed within from above discharges on parts 210 and the control cylinder 250, and this outer sleeve has negative thread 268, is used to make coupling assembling to be connected with target container.On the inboard of outer sleeve, be provided with one around operation step 269.

Between outer sleeve 267 and control cylinder 259, reach circlewise and be provided with seven retaining pawls 260 separatedly with even distance.These retaining pawls respectively have L shaped cross-sectional plane and have locking section 262 and operation section 264 that roughly radially extends that roughly extends along axial direction 290.These retaining pawls 260 in the zone of locking section 264 in a not shown manner method be connected to each other circlewise by elastomeric plastics bridgeware.The elastic force of elastomeric plastics bridgeware makes the direction of the stop position shown in retaining pawl 260 towards Fig. 3 a press all the time.Upper end of control cylinder 250 and sleeve segment 220 a coil spring can be set between the flange that extends internally above this upper end so that produce one to shown in prestrain in the stop position.

Fig. 3 a illustrates coupling assembling and is connected preceding state with target container.In this state, the close session 252 of control cylinder 250 is positioned on the discharge orifice 240 of discharging cylinder 230, make do not have medium from unshowned, flow out with discharging the cylinder 230 bonded assembly out-put containers.Control cylinder 250 is impossible relative to discharging manually moving of cylinder 230 because the locking section 262 of retaining pawl 260 is being discharged on the cylinder 230 and is being forbidden moving of control cylinder 250 in the following manner by touching: thereby promptly it nearly middle-end reaches on the swing step 257 at control cylinder 250 with its distal end by touching on the axially extended safety flange 222 of discharge parts 210 and having stopped the shortening of the spacing of these parts by touching with it.

Set out by this state, coupling assembling is assembled on the unshowned extension running-on section of a target container with the flange segments 254 of control cylinder 250, and by negative thread 268 outer sleeve 267 is screwed on this extension running-on section regularly.Shown in Fig. 3 b, cause outer sleeve 267 relative motions of relative control cylinder 250 on direction 290b to reach the motion of the swing step 257 of the operation step 269 relative control cylinders 250 that also cause outer sleeve 267 thus thus.Consequently the operation section 264 of the retaining pawl between them 260 is around a tangential axis upset, because form of implementation integratedly, this also cause locking section 262 outwards elastic forces of the plastics bridgeware of opposing elastic tensions overturn and away from described safety flange 222 starlikely.The upturned position of the retaining pawl 260 shown in Fig. 3 b is a releasing position, discharges cylinder 230 and can move relative to control cylinder 250 in this position.

Fig. 3 c is illustrated in the coupling assembling in its open position, in this open position, discharges cylinder 230 relative control cylinders 250 and is pressed downward, and makes discharge orifice 240 no longer be covered by the close session 252 of control cylinder 250.Can pass from the medium of unshowned out-put container and to discharge the moving path 292 of cylinder 230 longshore currents and flow in the also unshowned target container.

The 3rd form of implementation is because its frame mode and simply especially favourable.These retaining pawls 260 constitute single annular element with bonded assembly plastics bridgeware, and these parts favourable reaching when assembling on making can be operated simply.The scheme drawing of a section of such annular element shown in Figure 4.Each retaining pawl 260 is connected to each other by each two plastics bridgeware 294,296.At retaining pawl 260 outwards during upset, mainly be the plastics bridgeware 294 on the top load that extended, the plastics bridgeware 294 of bottom is positioned near the of separately pivot center and is not subjected to or the load that not too extended on the contrary.

The birds-eye view of Fig. 5 illustrates a stop ring 360, and it can be used to replace retaining pawl 260 in the coupling assembling of Fig. 3 a to 3c.This stop ring 360 has an annular disk 362 and reaches 12 retaining pawl projectioies 364 that are arranged on this annular disk 362 altogether.These retaining pawl projectioies 364 separate each other equably in abutting connection with the inner periphery ground setting of this annular disk 362 and along this inner periphery.These retaining pawl projectioies 364 respectively have the cross-sectional plane of rectangle and extend out from this annular disk 362 perpendicular to this annular disk ground.

As has already been described, stop ring 360 can replace retaining pawl 260 to use in the device of Fig. 3 a to 3c.Therefore, the inner periphery of annular disk 362 support by boss and when screwing on coupling assembling in the outer circumferential area of annular disk 362, in Fig. 6 downwards, apply a power.Annular disk 362 is flexibly distortion thus, and in the case, described inner periphery remains essentially on the same position, and excircle is pressed downward in the view of Fig. 6.Because retaining pawl projection 364 constitutes one with annular disk 362, thus the distortion by annular disk 362 make these retaining pawl projectioies with shown in its Fig. 6 not with annular disk 362 bonded assembly upper ends radially to extrinsic deflection.Can make the coupling assembling release thus.

Because the elastic deformation of annular disk 362, this annular disk will be got back to again in its virgin state shown in Figure 6 when taking off coupling assembling, and also move and get back in its stop position in the upper end of retaining pawl 364 simultaneously.

Be illustrated in the section-drawing of retaining pawl projection 364 locational stop rings along the section drawing line VII-VII among Fig. 5, among Fig. 7.Can see that by this figure annular disk 362 and retaining pawl projection 364 are configured one and for example are configured to injection-moulding plastic spare.In the intermediate space between two retaining pawl projectioies 364, the inner periphery of annular disk 362 is tilted.One of annular disk 362 and retaining pawl projection 364 opposed downsides have determined that the minimum inner periphery of stop ring 360 and inwall lean-out between two retaining pawl projectioies 364 of annular disk 362 tiltedly extend towards the upper side of annular disk 362.Can improve the movement of retaining pawl projection 364 and obtain advantage when stop ring 360 demouldings (Entformung) by these measures.

The section drawing of Fig. 8 is represented along the section drawing of the line VIII-VIII of Fig. 5 and can be clear that the bevelled embodiment of the inner periphery of annular disk 362.

In a word, by the stop ring 360 of one favourable and failure-free retaining pawl parts extremely in the case on the manufacturing cost in large quantity, these retaining pawl parts can stand a large amount of working cycle without a doubt.

Fig. 9 a, 9b and 9c represent according to the coupling assembling 400 of the 4th form of implementation of the present invention in three different conditions of charging process.Represent an off position as Fig. 9 a, in this off position, do not exist from a unshowned out-put container to a unshowned target container and the fluid that passes coupling assembling 400 to connect.The coupling assembling of Fig. 9 b presentation graphs 9a is in a control position, and in this control position, coupling assembling has been screwed around on the unshowned target container and has been in thus in the state of a release.At last, Fig. 9 c represents an open position of coupling assembling 400, in this open position, between unshowned out-put container and unshowned target container and pass coupling assembling 400 and form fluids and be connected.The setting on coupling assembling 400 of out-put container and target container with realize in conjunction with the identical mode of the described mode of Figure 15.

The coupling assembling 400 of Fig. 9 a has one and discharges cylinder component 402, and this discharge cylinder component comprises that the discharge cylinder 404 of the reality with a plurality of discharge orifices 406 and a sealing arrangement 408 are used for being connected of out-put container taking over 410 with one.In addition, be provided with a control cylinder 412 (this control cylinder has thereon the retaining pawl 414 of moulding integratedly), an outer sleeve 416 and the coil spring 418 of taking between 410 that is connected at outer sleeve 416 and discharge cylinder component 402.This coil spring 418 injection moulding integratedly is on outer sleeve 416 or discharge cylinder component 402.Connect to take over 410 with the adaptive external thread bolt connection of unshowned out-put container, make the interior space of out-put container with discharge that the formation fluid is connected between the cylinder component 402.Connect adapter 410 and be provided with a plurality of locking projectioies 420 that are distributed on its inner periphery in the top of screw thread within it, these locking projectioies can be sealed with the adaptive locking projection of unshowned out-put container.Will connect take over 410 be screwed on the out-put container fully after, coupling assembling 400 is connected to each other regularly with out-put container, the operation of the coupling assembling that also will describe below making and especially be screwed on the target container and the motion between its open position and off position can be only motion by out-put container realize.For this reason, no longer need to catch coupling assembling 400.This is especially under the inaccessible situation, for example have a bigger meaning in the engine room of a self-propelled vehicle.

Will connect take over 410 be screwed on the out-put container after, coupling assembling 400 also remains in the closed condition shown in Fig. 9 a.Even discharge cylinder component 402 when outer sleeve 416 moves when attempting to make, this moving only can be carried out on very little size, but can influence the closed condition of coupling assembling 400 in no instance.In the view of Fig. 9 a, discharge some backstops 422 that move through that cylinder component 402 relative outer sleeves 416 make progress and limit, by connect take over 410 projectioies 424 of outwards giving prominence to by backstop on these backstops.In the case, these projectioies 424 are directed in the longitudinal guide in outer sleeve 416 426 respectively.Therefore discharging cylinder component 402 only can be parallel to central longitudinal axis 428 ground and move relative to outer sleeve 416.Discharge cylinder component 402 move down by discharge cylinder 404 around outer lug boss 430 backstops be that the upside of L shaped retaining pawl 414 stops at cross-sectional plane.

Retaining pawl 414 is molded on the control cylinder 412 integratedly, this control cylinder again with one around outer shoulder 432 be bearing in outer sleeve 416 on the inwardly outstanding projectioies 434 of control cylinder 412.Thus, the relative motion of discharge cylinder 404 relative control cylinders 412 only can be carried out in very narrow boundary and under any circumstance also can not cause by out-put container by the release of discharge orifice 406 to the flow path of target container.

When even the connection that is screwed around coupling assembling 400 when out-put container is taken on 410, medium only can be arrived in the control cylinders 412 by discharge orifice 406 by out-put container, but by sealing arrangement 408 (the sealing device with one around sealing lip by touching on the inwall of control cylinder 412) be maintained in the annular space between the inwall of circumferential surface (described discharge orifice 406 is arranged in this circumferential surface), sealing arrangement 408 and control cylinder 412 of discharge cylinder 404.Can not flow out from this annular space at fluid on the direction of out-put container because on discharging on the cylinder 404 by moulding one around sealing lip 436, the sealing lip will stop described medium back flow in the zone between discharge cylinder 404 and the outer sleeve 416.

In order to discharge the flow path from the out-put container to the target container, coupling assembling 400 is reached in the control position shown in Fig. 9 b.This takes over by the connection that outer sleeve 416 is screwed in a unshowned target container and realizes.For this reason, outer sleeve 416 is provided with negative thread 438 in lower region thereof, and this negative thread will be screwed around on the corresponding outside thread that the connection of target container takes over.As mentioned above, take over to go up for the connection that makes coupling assembling 400 be screwed to target container coupling assembling 400 itself is rotated, but can realize by the rotation of common more accessible out-put container.Because out-put container is under any circumstance remained in the connection adapter 410 of discharging cylinder component 402 by nothing to a great extent with relatively rotating and discharges cylinder component 402 nothings by locking projection 420 and is arranged on the outer sleeve 416 with relatively rotating, so out-put container will cause around the rotation of central axis 428: whole coupling assembling 400 rotates together and negative thread 438 is screwed on the outside thread of target container.

After the connection that outer sleeve 416 is screwed to target container is fully taken over, the upper limb of target container outer sleeve 410 pressure-controlled cylinder 412 upwards relatively on by the position shown in the arrow 440.Thus, one on the outer sleeve 416 extend into outer sleeve 416 in-to-ins around projection 442 be pressed on the outwards outstanding contact surfaces 444 of retaining pawl 414, thus, retaining pawl 414 to extrinsic deflection and discharge discharge cylinder 404 around outer shoulder 430.Thus, discharge cylinder component 402 relatively outer sleeve 416 and relative control cylinder 412 move down, up to reaching the open position shown in Fig. 9 c.

When discharge cylinder component 402 relative outer sleeves 416 moved down, the relative outer sleeve 416 of control cylinder was maintained fixed, because the upper limb that the connection of target container is taken over upwards is pressed in control cylinder 412 on the projection 442 of outer sleeve 416 at 440 places, described position.Discharge moving down to be only required in and applying a power on the out-put container that is connected with coupling assembling 400 of cylinder component 402.In case sealing arrangement 408 by touch on the inwall of control cylinder 412 around the edge left control cylinder, the flow path between out-put container and the target container promptly is released.Then, from the liquid or loose medium of out-put container can by discharge cylinder 404 pass altogether six have the discharge orifice 406 of big cross-sectional plane and pass sealing arrangement 408 with the lower edge of control cylinder 412 between circular clearance arrival target container.Because the big cross-sectional plane of discharge orifice 406 can carry out Medium Replacement by at high speed.

The open position of the coupling assembling 400 shown in Fig. 9 c is represented a terminal location because in this position, discharge cylinder 404 usefulness its around outer shoulder 430 backstops on the back side of retaining pawl 414.In addition, discharge of cylinder 404 be arranged on described around the frustoconical outer surface backstop of outer shoulder 430 belows be similarly on the inside face of truncated cone shape and the control cylinder 412 that prevents from thus to discharge in the view of cylinder 404 relative Fig. 9 continues to move down of control cylinder 412.

In order to interrupt the flow path between out-put container and the target container, out-put container is drawn back deviating from the direction of target container.Under the situation of the respective configuration of coil spring 418, this return movement automatically carries out, and makes only need unclamp out-put container or reduce to upward pressure towards target container side in order to interrupt flow path.Arrive the control position shown in Fig. 9 b of coupling assembling 400 again after out-put container is retracted fully, take over as long as outer sleeve 416 also is screwed around the connection of target container, this coupling assembling just remains on this control position always.After screwing down from the connection adapter of target container coupling assembling 400, control cylinder 412 relative outer sleeves 416 move downward again, up on the projection 434 of its protruding 432 backstops at outer sleeve 416 and till retaining pawl 414 is moved back in the stop position shown in Fig. 9 a again.

Therefore only when being screwed around on the target container, coupling assembling 400 just can carry out the emptying of out-put container.In the closed condition shown in Fig. 9 a, a plurality of retaining pawls 414 with the ring arranged in form have prevented to pass the release of the flow path of coupling assembling 400 reliably.

The view of Figure 10 is represented the birds-eye view of the discharge cylinder component 402 of dissecting along a mid-plane XI-XI.Can be clear that among the figure to be arranged on the annular knurl of connect taking in 410 the zone 448 that this annular knurl makes discharges cylinder component 402 and become easy to screwing of taking over of the connection of out-put container.Can be clear that equally that in the locking projection 420 of connect taking on 410 inner peripherys they are sealed with the adaptive locking projection of taking over being connected of out-put container and play thus prevent to discharge the effect that cylinder component 402 rotates on out-put container in the state of screwing fully.

Discharge orifice 406 is set in the shell of the section that of discharging cylinder 404 dwindles towards the direction taper ground of target container and provides a very big free cross-sectional plane for medium to be exported.

A view of the discharge cylinder component 402 of being dissected in the view table diagrammatic sketch 10 of Figure 11.Can be clear that projection 424 among the figure, these projectioies can be directed in the adaptive guide piece of outer sleeve 416 and be used for making and discharge cylinder component 402 and do not have and relatively rotate but axially movably be arranged on outer sleeve 416.Can be clear that in addition around sealing lip 436, the sealing lip is molded on the excircle of discharging cylinder 404, this excircle is at a cylindrical sector and be provided with on the transition portion between the truncated cone shape section of discharge orifice 406.Connecting a cylindrical sector 450 on this is provided with the truncated cone shape section of discharge orifice 406, sealing arrangement 408 can utilize its adaptive linkage section to be enclosed within on this cylindrical sector and be fixed on the there.In the zone of this truncated cone shape section, also can see: between out-put container and target container carry out Medium Exchange the time contrary retaining described outflow the surface 452 of medium be configured to taper, make the tip of this flat conical suface 452 discharge the medium that cylinder 404 flows out against described passing from out-put container.Guarantee to discharge good in the cylinder 404 and the little flow condition of loss as far as possible by conical suface, can carry out Medium Exchange by at high speed thus.

The view of Figure 12 represents to be cut into the outer sleeve 416 of half.To Fig. 9 a, the view of 9b and 9c additionally can be seen the dead bolt 454 on the lower edge of outer sleeve 416, and these dead bolts are inwardly outstanding and can cooperate with the adaptive locking projection of taking over being connected of a target container from the inner periphery of outer sleeve 416.These locking projectioies 454 can additionally guarantee: coupling assembling 400 under any circumstance all is engaged on the target container regularly, and the danger that coupling assembling 400 by mistake screws off from target container can not occur between loading period.What conform with purpose in the case is, these locking projectioies 54 are set in this wise, only makes that the retaining pawl 414 among Fig. 9 b just deflects in the releasing position when the adaptive protruding cooperation of corresponding locking on the projection 454 of the locking on the outer sleeve 416 and the target container.These locking projectioies 454 and the layout on the inner periphery of outer sleeve 416 thereof also can be seen from Figure 13.

The view of Figure 14 is represented a section drawing that has the control cylinder 412 of the retaining pawl 414 of integral injection molding on control cylinder 412.

The section drawing of Figure 15 is represented the 4th form of implementation of a coupling assembling 500 of the present invention.For coupling assembling 500 only with Fig. 9 a, 9b, detailed explanation is made in coupling assembling 400 those different part aspects of 9c.The discharge cylinder component 402 of discharging cylinder component 502 and coupling assembling 400 constitutes in the same manner, only is to be provided with a flexible pipe connection adapter 507 to replace discharge orifice in the frusto-conical region that is provided with discharge orifice 506.Connect to take in 507 at this flexible pipe and inserted an exhaust hose 510, this exhaust hose has formed being connected between out-put container 520 and (between the inwall of discharge cylinder 504, sealing arrangement 508 and control cylinder 512) annular space 514.In the case, extend in the interior space of out-put container 520 to exhaust hose 510 such degree, make it coupling assembling 500 and out-put container 520 be screwed around the liquid level of a state inside on the target container 522 in out-put container 520 above.Express the connection of target container 522 with in the view of Figure 15, only schematically reaching section and take over the zone.Thus, with can make during target container carries out Medium Exchange by flow into medium in the target container 522 squeeze the air that is connected by flexible pipe take over 507 and exhaust hose 510 arrival out-put containers 520 in.Therefore can carry out the beidirectional Medium Exchange under the situation of using coupling assembling 500, promptly liquid or loose medium arrives target container by out-put container 520 and squeezes the air that and arrives out-put container 520 by target container 522 simultaneously.Under the situation of corrosive or deletrious medium, can realize an osed top system during Medium Exchange thus.

As appreciable in the view of Figure 15, out-put container 520 have one with its installation situation adaptive, have one and be connected the shape that it is connected the frusto-conical region of taking over.The columniform section on this frusto-conical region, common that is connected of out-put container 520 is designed to a polygonal excircle, so that out-put container 520 can be grasped by the operator, make only can be screwed to coupling assembling 500 on the target container 522, open this coupling assembling and carry out to screw this coupling assembling following again from target container 522 after the Medium Exchange as described above by operation to out-put container 520.

The lateral plan of Figure 16 is represented an out-put container 600 of the present invention, and it can be connected with above-mentioned coupling assembling.For this reason, the bottle screw thread 602 of this bottle 600 is with a coupling assembling, for example be connected with the outer sleeve of this coupling assembling.Even under very narrow space situation, for example in the engine room of a self-propelled vehicle, can operate the out-put container 600 that has the coupling assembling of screwing and especially in order only can to adjust the diverse location of coupling assembling by the operation of bottle 600, this out-put container has two dactylotome 604 and 606, cross-sectional planes are dodecagonal main body 608 and also have finger to grab chamber 610 well.These fingers are grabbed the depression that chamber 610 is configured to the cylinder segment shape respectively, and the longitudinal axis of these depressions is parallel to the vertical axis extension of bottle 600.These a plurality of fingers are grabbed chamber 610 and are arranged in this wise each other with nestling, make per two fingers grab chamber 610 and interconnect by a bridgeware 612 that extends along the longitudinal direction of bottle 600.All fingers are grabbed chamber 610 and are distributed and be set at the tight top of the foundation ring 614 of bottle 600 around the excircle of bottle 600 circlewise, at the bottom of this foundation ring then carries out the transition to bottle 616.Grab at the finger that is circular layout and to be provided with first reinforcing pad 618 between chamber 610 and the main body 608, it strengthens bottle 600 rigidity that preferably are made of plastics.Between main body 608 and dactylotome 606, be provided with another reinforcing pad 620, between two dactylotome 606 and 604, be provided with one the 3rd reinforcing pad 622.Set out by bottle screw thread 602 and at first to follow locking projection circle 624, it is used in the fixedly maintenance in the connecting thread of coupling assembling.Connecting the zone 626 that a taper enlarges behind locking projection circle 624, should the zone transition be first dactylotome 604 then.In the zone of first dactylotome 604, also carry out the expansion of the cross-sectional plane of bottle 600, only in the zone of reinforcing pad 622, just reach the maximum gauge of bottle 600.

After a coupling assembling is swirled on bottle screw thread 602 (wherein bottle 600 closing device can automatically be severed when screwing coupling assembling), during coupling assembling is then in the closed position as described above.In order to make the coupling assembling that has the out-put container 600 of screwing reach control position, the connection that coupling assembling must be assembled to, for example be screwed to a target container is taken over.This can only realize by the operation to out-put container 600.Its mode is grabbed in one or two dactylotome 604,606 and operator's another hand is grabbed on foundation ring 614 and at least one finger is grabbed in the chamber 610 for first hand of operator.When out-put container 600 rotated, this rotational motion grabbed at finger with grabbing that hand on the chamber 610 applies and the finger of another hand can slide along dactylotome 604,606.The coupling assembling that can even will have an out-put container 600 with one hand soon after being placed on the target container continues to be screwed on the target container.As described above, this coupling assembling can reach open position and turning back in the control position again by the simple operations to out-put container 600, and for example after out-put container is emptied completely, this out-put container can be backed out from target container with coupling assembling.

Figure 17 a, the section drawing of 17b and 17c represent the 6th form of implementation of of the present invention a, coupling assembling in different conditions 702.

At Figure 17 a, in the view of 17b and 17c, coupling assembling 702 is connected with a target container 704, and its mode is that the outer sleeve 706 usefulness negative threads 708 of coupling assembling 702 are screwed in the spiral adapter 710 of target container 704.At this, for target container 704 section ground and take over 710 with its spiral and represent only.

In the state of Figure 17 a, coupling assembling 702 also is not screwed around on the target container 704 fully and still is arranged in the off position of locking.According to the view of Figure 17 b, the spiral that coupling assembling 702 fully is screwed around target container 704 is taken on 710 and is arranged in control position, though coupling assembling does not also allow the medium percolation in this control position, is in the released state.At last, Figure 17 c represents the open position of coupling assembling 702, and in this open position, medium can flow to the target container from unshowned out-put container according to arrow 712, and conversely, air can flow back into the out-put container from target container according to arrow 714.

Can see by Figure 17 a: coupling assembling 702 has one and discharges cylinder 716, and this discharge cylinder is provided with a tapped joint component 718 integratedly, and coupling assembling 702 can be screwed around in the spiral adapter of a unshowned out-put container by this joint component.This coupling assembling also has a control cylinder 720, and described discharge cylinder is directed in this control cylinder movably and the discharge cylinder in the off position shown in Figure 17 a seals by two seal rings 722 and 724 relative these control cylinders.As passing through Figure 17 a, 17b and 17c are appreciable, under control cylinder 720 fixed situations, by discharging cylinder 716, make medium to flow through coupling assembling 702 and air can flow back into out-put container again by discharge orifice 726 and an exhaust hose 728 on the contrary according to arrow 712 according to the discharge orifice 726 that moving down of arrow 700b can discharge this discharge cylinder.Seal ring 722,724 is used for: do not flow out even the medium that is highly susceptible to leaking does not have medium in during the state shown in Figure 17 a also can be maintained at reliably in the coupling assembling 702 and especially be screwed on the target container 704.

In the off position shown in Figure 17 a, the motion of discharging cylinder 716 relative control cylinders 720 is stoped by retaining pawl 730 to a great extent, and these retaining pawls have L shaped cross-sectional plane and have a stop leg 732 respectively and an operation leg 734.The even each other compartment of terrain of a plurality of retaining pawls 730 is around the circumference of columniform discharge cylinder 716.These a plurality of retaining pawls 730 for example keep by unshowned elastic bridge fitting in the stop position shown in Figure 17 a, for example example ground label 294,296 expressions in the explanatory view of Fig. 4 of these bridgewares.Conversion ground, retaining pawl 730 can be connected to each other by a continuous ring in the zone of its operation leg 734, this ring for example by example be illustrated in Fig. 5 and 6.

As can be seen, discharge of discharging cylinder 716 when cylinder 716 moves downward behind the stroke of a weak point around and outward extending protruding 736 will run on the corresponding free upper end of stop leg 732 of retaining pawl 730.Can stop discharge cylinder 716 relative control cylinders 720 to move downward thus according to arrow 700b.

On the opposite sense that makes progress, promptly according to arrow 700a, discharge cylinder 716 by spring 738 prestrains, wherein, the following mode that moves through upwards is prevented from, promptly one of joint component 718 outward extending, around boss by touch at outer sleeve 706 one same around, on projecting inward projection.Therefore, on screwing before the coupling assembling 702, the prestrain of this coupling assembling by spring 738 is maintained in the off position shown in Figure 17 a and owing to is in the power that retaining pawl 730 in the stop position can not antagonistic spring 738 and moves in the open position shown in Figure 17 c.

In the view of Figure 17 b, outer sleeve 706 fully is screwed to the spiral of target container 704 and is taken on 710, thus, one of outer sleeve 706 be positioned at operation leg 734 tops of retaining pawl 730 and extend internally, around the state of the relative Figure 17 a of boss move downward and form by touching and should operate leg 734 with the upper side of this operation leg 734 thus to having pressed down a segment distance.Because be bearing in swingably in the transitional region of retaining pawl 730 between operation leg 734 and stop leg 732 one of control cylinder 720 around protuberance 742 on, so the stop leg 732 of these retaining pawls 730 is thus to extrinsic deflection.So the inflexed end of stop leg 732 from discharge cylinder 716 around the path of motion of boss 736 shift out, but make the power of the present antagonistic spring 738 of this discharges cylinder move down.

Moving down the last state that reaches in back fully corresponding to open position and be indicated among Figure 17 c.In this open position, spring 738 is compressed fully and stops discharge cylinder 716 to continue to move downward thus.But can determine: retaining pawl 730 differently shifts out from the path of motion of discharging cylinder 716 fully with the form of implementation shown in Fig. 3 a to 3c, makes that discharge cylinder 716 and especially its annular boss 736 can be fully in the next door of retaining pawl 730 motion processes.Can be readily seen that: the inflexed free end of the operation leg 732 that this can be by retaining pawl 730 reach and thus (by discharging the respective configuration of cylinder 716) can realize the very large stroke of opening, this can discharge very large passage section.

Can reach high through flow velocity by the Medium Exchange that between out-put container and target container 704, is provided with according to the present invention.To side by side replace from the medium that out-put container flows to the target container according to arrow 712 by the air that flows back to according to arrow 714.In order to guarantee effective exhaust of target container 704 between loading period, extend in the out-put container to exhaust hose 728 such degree, make when the charging process the begins free end of this exhaust hose be arranged in out-put container the medium liquid level above.

Coil spring 738 both can be configured to steel part also can be configured to plastic components.This will be easy to the recycle of coupling assembling 702 significantly, because this link can be made by plastics, especially identical plastics except that seal ring 722 and 724 thus fully.

In the zone of the discharge orifice 726 on discharging cylinder, a plurality of discharge orifices 726 that distributing on the circumference of discharging cylinder 716 make this discharge cylinder be opened in about 270 ° altogether angular range.

Control cylinder 720 have one outward extending, around flange 744, the contact of this flange is taken on 710 the upper end and the terminal location of fixed control cylinder 720 on target container 704 thus at spiral after being screwed on the target container.Thereby for make this around flange 744 and make coupling assembling 702 reliably relatively target container 704 seal, should around flange 744 its be provided with on the downside of target container 704 one around projection 746, this protruding cross-sectional plane be triangle and with its most advanced and sophisticated contact on the upper side of the spiral adapter 710 of target container 704.When being screwed in outer sleeve 706 on the target container 704, this projection 746 is crushed and has guaranteed positiver sealing between coupling assembling 702 and the target container 704 thus.Because retaining pawl 730 only when one predetermined, relevant and could deflect into the releasing position from its stop position after stroke is finished with relevant the screwing of power with stroke, so also guaranteed: this projection 746 (it satisfies the function of seal ring) is sealed in spiral reliably and is taken on 710.
