Specific embodiment
Referring initially to Fig. 1 to Fig. 3.
It is seen in the figure that refuelling accessory 1.Refuelling accessory 1 is built into around longitudinal axis L rotational symmetry.It should plus fire Expect that accessory 1 has hollow matrix 2, which has the accommodating chamber 4 being located therein.Accommodating chamber 4 is configured essentially to open tubular column Shape and the bottom 4a and entrance opening E with end side.It can be by (the i.e. refuelling depot side of infrastructure side via opening E is entered ) refuelling equipment 19 is inserted into accommodating chamber 4.
It may recognize that, refuelling equipment 19 has inserting depth l1, which is less than the length l2 of accommodating chamber 4.By This, is configured with distance between the end 19a of the end side of the bottom 4a and refuelling equipment 19 of accommodating chamber 4.The distance is preferably It is about 1mm to about 8mm.Preferably, refuelling equipment 19 is configured to plug-in female connector (Nippel, otherwise referred to as casing).
As can be seen, refuelling equipment 19 has central bore 20, which, which leads to, radially outward leaves Drilling 21 in.Specifically, there are four dislocation with about 90 ° of drilling 21.
In order to seal refuelling equipment 19 relative to refuelling accessory 1, two are misplaced on the direction of longitudinal axis L Lip ring 22a, 22b brought into the circular slot of refuelling equipment 19.Specifically, lip ring 22a is for making The gas of inflow will not leave from refuelling accessory 1 again on the contrary with the reversed B of refuelling.Lip ring 22b is for preventing The gas of entrance is between the bottom 4a of accommodating chamber 4 and the end 19a of the end side of refuelling equipment 19.As a result, at no pair In the case where answering measure (Gegenma nahme), pressure pad (Druckpolster), the pressure pad can be constructed during refuelling It will lead to refuelling equipment 19 to extrude from accommodating chamber 4.
Accommodating chamber 4 is brought into the matrix 2 of refuelling accessory 1.The interconnecting piece 3a and 3b of channel-type are also in accommodating chamber 4 It is passed through in front, entrance region, the interconnecting piece 3a and 3b of the channel-type establish accommodating chamber to the company that chamber 7 is discharged It connects.Therefore, the interconnecting piece 3a, 3b of channel-type are for being delivered up gas from accommodating chamber 4 in the side of discharge chamber 7.In refuelling side To on B, preposition interconnecting piece 3a, the 3b in channel-type in open area 5, the open area 5 is led in accommodating chamber 4.
After being inserted into refuelling equipment 19, open area 5 is located between the lip ring 22a, 22b being already mentioned above. Under normal circumstances, it therefore does not leak, and the gas flowed out from drilling 21 can reach open region without loss In domain 5 and thus in the interconnecting piece 3a, 3b for reaching channel-type.
In situation preferably strikingly, the interconnecting piece 3a of channel-type is with angle [alpha] relative to longitudinal axis Line L orientation, and with the angle [alpha] on the B of refuelling direction far from longitudinal axis L.The wall portion of open area 5 is equally with the angle Extension.And then, the interconnecting piece 3a of channel-type meets on the interconnecting piece 3b of channel-type, and the interconnecting piece 3a of the channel-type leads to described The interconnecting piece 3b of road formula is in the connection in pressure techniques.The interconnecting piece 3b of channel-type is taken with angle beta relative to longitudinal axis L To, wherein it is continuously reduced in the interconnecting piece 3b of refuelling direction B, the channel-type relative to the distance of longitudinal axis L.? In embodiment, angle [alpha] is preferably about 15 to 25 °.Preferably, angle beta is about 10 to 20 °.By the design scheme, on the one hand So that the very compact of matrix 2 is constructed to possibility, on the other hand, which helps that the gas of inflow can be significantly improved Body is from refuelling equipment 19 until the flowing of discharge chamber 7 is moved towards.
If the decrease of lip ring 22a and especially 22b should occur for senile cause or use with causing Sealing function, the then gas flowed into can also be reached via the intermediate space of the peripheral side between refuelling equipment 19 and matrix 2 Until the intermediate space formed between the end 19a of the end side of the bottom 4a and refuelling equipment 19 of accommodating chamber 4.In order to this The extrusion that refuelling equipment 19 can be effectively prevented in situation, in the adjacent region of the bottom 4a of accommodating chamber 4, by channel-type Interconnecting piece 6 be brought into matrix 2, opening led in accommodating chamber 4 in peripheral side.The interconnecting piece 6 of channel-type is radial from receiving Chamber 4 extends outward to be come, and establishes the connection between accommodating chamber 4 and ambient enviroment U.Therefore, in this region due to letting out Draining to the gas reached can flow out in ambient enviroment without barrier, and the pressure structure between the end 19a of bottom 4a and end side It is impossible for building.
As furthermore can as seen from Figure 1 as, the interconnecting piece 3b of channel-type lead to discharge chamber 7 in.Matrix 2 also has spiral shell Line 14, the screw thread 14 are used for the screw-in of casing component 10.Casing component 10 is for accommodating non-return unit 11.In casing component 10 The annular of convex shoulder casing 16b and filter 8 are maintained between the end of end side and the internal shoulder 9a that chamber 7 is discharged in a manner of clamping End 9.In the region of filter 8, discharge chamber 7 is so constructed, so that major part of the discharge chamber 7 for its length Concentrically surround filter 8.Thus, it can be achieved that optimal filter effect of the filter 8 to gas, company of the gas from channel-type The outflow opening 3c of socket part 3b is upward out in the side of filter 8.
In addition, the length of outflow opening 3c equally extends in the major part of the length of filter 8 respectively, this additionally has Help improve 8 filtration.Filter 8 is configured to grating type.It was flowed through by the gas that outlet opening 3c leaves Filter 8 and opening 15 is reached via by portion 12, which is closed by spherical parts 16.Spherical parts 16 by with refuelling Direction B opposite back edge is squeezed against opening 15.
In this embodiment, back edge is triggered by toroidal magnet 16a, toroidal magnet 16a, which is applied to, to consist of metal Spherical parts 16 on.However, by other forms and in a manner of, for example by spring force generate back edge be also feasible.However, The pressure for being flowed into the gas in refuelling accessory 1 is so big (until about 200bar) so that spherical parts 16 with it is described Back edge is squeezed on the B of refuelling direction on the contrary and is detached from opening 15.Gas can be by being passed through by portion 12 as a result, Spherical parts 16 are through the flowing of overflow ducts 13 shown by dashed lines and finally reach outlet opening A via passing away 13a.
Outlet opening A is the component part of the fixation protrusion 18 of casing component 10, the fixation protrusion 18 be used for not The pipe jointing part (Rohrverbindung) being shown specifically is screwed on to the gas container not being shown specifically equally herein.Via nut 17 realize casing component 10 and thus fixation of the refuelling accessory 1 at the wall portion for the motor vehicle not being shown specifically.Therefore, lead to The toroidal magnet 16a of the component part of receipt member 11, opening 15 and spherical parts 16, realize the function of check-valves until crossing.
In Fig. 2, refuelling accessory 1 is shown from side.The non-return unit for having marked matrix 2 and being screwed on the matrix 2 10.Furthermore, it can be seen that from matrix 2 radially away, the interconnecting piece 6 of channel-type.In the figure, instead of refuelling equipment 19, It can be seen that closing cock 23, which is pushed into accommodating chamber 4 and can not be maintained at losing by means of holder 23a At matrix 2.
Interconnecting piece 3b and 6 be separated from each other, channel-type can be particularly well found out in Fig. 3.There are four channels The interconnecting piece 3b (or 3a) of formula and the interconnecting piece 6 of four channel-types.It is evident that one side channel-type interconnecting piece 3b (and by This same 3a) and the interconnecting piece 6 of another aspect channel-type be arranged in matrix 2 with missing one another with about 90 ° of angle.Work as channel The interconnecting piece 3a of formula, when 3b extends along longitudinal axis L, the interconnecting piece 6 of channel-type is stretched outward from accommodating chamber 4s to surrounding Environment U.
If refueling process terminate and again from accommodating chamber 4 pull out refuelling equipment 19, it is in accommodating chamber 4 and And it is thus also in the interconnecting piece 3a, 3b of channel-type and in discharge chamber 7 in refuelling accessory 1 and final also logical The interior pressure crossed in portion 12 suddenly drops in the external pressure of ambient enviroment U.In this case, the ball deviated in Fig. 1 Shape part 16 due to existing, fuel tank side back pressure (Gegendruck, otherwise referred to as back-pressure) cause ground again with refuelling direction B Movement is returned on the contrary.Therefore, opening 15 is closed further through spherical parts 16.By this movement of spherical parts 16, ball will be located at The gas of residual volume before shape part 16 is pressed back into filter 8 on the contrary with refuelling direction B and is pressed back into from this In the interconnecting piece 3b, 3a of channel-type.Thus, it can be achieved that the very effective automatically cleaning of filter 8.Also support in the following manner With improvement automatically cleaning, i.e., 90 ° of steerings are avoided in the flowing trend of the interconnecting piece 3a, 3b of channel-type.
Now, the second embodiment of refuelling accessory 100 is illustrated in more detail with reference to fig. 4 to fig. 6.Refuelling accessory 100 has There is the working principle similar with the working principle of previous embodiment.The refuelling accessory 100 is equally built into rotational symmetry, band There is matrix 102, accommodating chamber 104 is brought into the matrix 102.Here, in the adjacent region of bottom 104a, four channels The opening of the interconnecting piece 106 of formula is also passed into accommodating chamber 104.The interconnecting piece 106 of channel-type extends radially outwardly.Accommodating chamber 104 Length l2 be configured to the inserting depth l1 greater than refuelling equipment 119.In this way, in bottom 104a and refuelling equipment Between the end 119a of 119 end side, and the collecting chamber for being used for possible gas leakage is formed, the possible gas leakage can The interconnecting piece 106 for passing unopposed through channel-type flows outwardly.
Refuelling equipment 119 has central bore 120 and the drilling 121 from the central bore 120 radially away again.It flows into Gas the connection that channel-type is reached in open areas 105 of accommodating chamber 104 and from this is reached by these drillings In portion 103.In the situation of the refuelling equipment 119 of insertion, but on the direction of longitudinal axis L in two sides by lip ring 122a, 122b sealed opening region 105.As furthermore can be seen that, the interconnecting piece 103 of channel-type is nearly parallel to longitudinal axis Line L extension.
Connector 124 is reached in the end of the interconnecting piece 103 of channel-type in the gas of refuelling direction B, inflow Circular ring type recess 107a.Matrix 102 is screwed into connector 124 by means of screw thread 125, which is present in matrix On 102 end 126.After the recess 107a of circular ring type, the gas of inflow via matrix 102 end 126 it is radial By being open, 107b is reached in the discharge chamber 107 in end 126.A part of accommodating chamber 107 was concentrically surrounded again Filter 108.As also in the aforementioned embodiment, this helps optimally to make full use of filtration.
Casing component 110 is screwed into connector 124 by means of screw thread 114 again.Non-return unit 111 is embedded in housing portion In part 110, and it is identical as those of non-return unit 11 in its construction and in its function.In addition, in casing component 110 Maintain end 109 and the convex shoulder casing of the annular of filter 108 again between the circular internal shoulder 109a of connector 124 116b。
By spherical parts 116, the opening 115 of the end by portion 112 of convex shoulder casing 116b can be enclosed in.However, It is such case only when constructing back pressure not over the gas of inflow.In this case, and adding spherical parts 116 It is moved on the B of fuel direction, release opening 115, and gas can be via overflow ducts 113 in passing away 113a and outlet opening The side of A is upward out.Outlet opening A is the component part for having threaded fixed protrusion 118.It can by toroidal magnet 116a The additionally closing force on supporting function to spherical parts 116.When the back pressure of stuffing pressure and fuel tank side almost has same size When, then this is especially significant.Instead of passing through toroidal magnet, it is also contemplated that in other ways, for example pass through spring force life At this holding power.
