, 3 2 ,, SUMMARY OF THE INVENTION
The invention is based upon the task of forming a tank closure of the hereinabove mentioned type in which the danger of an injury or annoyance of the user by fluid droplets contained in the gas-outlet stream is larg~ly avoided.
This task is solved, in that the guide tube exhibits a t~pered segment and in that exit openings are provided at the side of the tapered segment which lies to the pour-in socket-piece, through which the gases pass out of the guide tube to the outside, and in that inlet openings are arranged at the side of the tapered segment which i5 turned away from the tank, through which the gases in the interior of the guide tube enter, and in that a lead-apparatus connecting the exit openings and the inlet openings in a moderate flow is provided.
In the tank closure according to the invention the gas stream which escapes from the tank during filling thereof is turned back several times, namely once radially outwardly and thereafter again radially inward in the interior of the guide tube, so that fluid droplets are thrown away onto this path and ¦20 leave the gas stream.
A lead apparatus, which in a preferred embvodiment of the invention consists of a housing which surrounds closely the guide tube and the orifice- rim of the pour-in socket, takes care of the turning-back of the gas stream. The vapors which escape from the tank thus cannot escape into the open, but are compelled by the housing to flow again through the inlPt ~ LJ ~ 2 openings into the interior of the guide tube.
According to a further embodiment of the invention the guide tube exhibits a stop for a shoulder of the refueling s nozzle. Modern refueling nozzles for petrol exhibit a ring ~ 5 collar with slanting surfaces, to which the guide tube is ,i adapted and for which the guide tube forms the mentioned stop.
According to a further development of the invention the guide tube is axially displaceable and advantageously ~4 elastically pre-stressed in a direction away from the pour-in openiny. At the outside of a self-locking closure apparatus dirty water gathers, in particular in the case of tank socket pieces of motor vehicles, during the course of operation. The danger arises that this dirty water gets to the interior of the tank during opening of the closure apparatus of the r~fueling :j ',15 nozzle. In order to prevent this, in a further advantageous ~1 embodiment of the invention the housing is provided with run-off q openings at the top of the pour-in opening, which advantageously i-rii3 ~re closeable during filling of the tankO By means of these run-off openings dirty water can be led away, which otherwise would gather in front of the closure apparatus.
;~.
Since the run-off openings are closeable during filling of the tank, it is prevented that the gases escaping from the tank `~
get to the open in the same route , ~
The closeability of the run-off openings is advantageously , )5 achieved in such a way that, in a further advantageous ~I
;`~
~.
,1~
embodiment of the invention, a packing which closes the run-off openings upon introduction of the refueling nozzle is arranged ~- in the axially-displaceable guide tube. The packing is so arranged that upon axial displacement of the guide tube by introduction of the refueling nozzle the closure function is fulfilled automatically.
In a further advantageous embodiment oE the invention the housing exhibits a projection lying near the stop for the shoulder of the refueling nozzle, in such a way that the `
shoulder of the refueling nozzle is capable of resting between the stop and the projection. By means of this projection the ( refueling nozzle is held securely, during filling, in an exactly j defined position.
The invention will hereinafter be explained in more detail L5 with reference to two exemplary embodiments shown schematically in the Figures. -. .~, BRIEF DESCRIPTION OF THE DRAWINGS

In Figure 1 may be recognized a pour-in socket-piece 1 of a motor vehicle, which exhibits a pour-in opening 3, which is closed off by a closure flap 2. The closure flap 2 consists of a bearing-arm 12, which is rotatably mounted on a shaft 13. By ! means of a spring (not shown) the bearing arm is pre-stressed in ¦ the direction of the pour-in opening 3. A closure body 14 is fixed to the bearing arm; the closure body 14 exhibits a circumferential groove in which a packing 20 is arranged. As 110 may be recognized from Figure 1, the closure body 14 passes with ! its packing 20 sealingly in the pour-in opening 3, so that in this condition the pour-in opening, especially by the operation of the pre-stressing spring, is tightly closed. At the rim of the pour-in opening 3 of the pour-in socket-piece 1, six pegs 15 extending in the longitudinal direction are arranged, of whi'ch only four may be recognized in the sectional representation of Figure 1. The pour-in socket-piece 1 is in its orifice-region surrounded by a headpiece-type housing 8, which exhibits a ¦ somewhat reduced diameter at the side of the pour-in opening ¦20 facing away from the tank side. The rim of the housing 8 is turned down inwardly at its free end. At one side (left in the drawing) the turned-down rim region forms a rectilinearly running projection 11 (see also Figure 2). In the top of the . closure flap 2, the housing 8 exhibits two run-off openings 9.
A guide tube 5 is arranged inside the cylindrical housing S
, ~ ~ .
8. The guide tube 5 exhibits a conical segment 5b, which`serves as stop for a correspondingly formed ring collar of a refueling 1l nozzle. The conical segment 5b goes over into a cylindrical f segment with reduced radius, which is designated hereinafter as reduced-scale segment 5a. In the neighborhood of the conical segment 5b, mounted somewhat further in the direction towards ,~ the pour-in opening 3, the guide tube 5 is provided with a total ; of eight radial borings, which serve as inlet openings 7 for , .
yases escaping from the tank during filling, which will be described in detail hereinafter. The end rim of the guide tube -5 which faces the pour-in opening 3 exhibits a space with respect to the rim of the pour-in opening, so that an annular exit opening 8 is formed.
The guide tube 5 is axially displaceable inside the housing 8. A cylinder part 16 lying at the inner wall of the housing 8 serves for the axial guidance of the guide tube 5. A tilting of the guide tube 5 during axial displacement is prevented by the rods .. ~ ..
15 which surround the cylindrical segment 5a and in this manner present an axial slide-guide. The guide tube 5 is loaded by a , compression spring 17, which is supported on the orifice rim of i~1 the pour-in opening 3, in such a manner that it is moved away from the pour-in opening.
:' ; The guide-tube 5 exhibits a circumferential plank which is directed radially towards the outside, against which the other end of the compression spring 17 is put. The plank 18 lies ' "
'~ I ..
.,'~
above the inlet openings 7 in the drawing, i.e. it is further removed from the orifice opening than the inlet openings 7. The ' plank 18 carries a circumferential packing 10, which exhibits roughly the form of a truncated-cone jacket. The packing 10 is , 5 so dimensioned that it, in the position of the guide tube 5 ¦ shown in Figure 1, does not extend to the pour-in socket-piece 1, and in particular does not close the run-off openings 9. In the rest position of the fuel tank closure thus no dirty water ! can accumulate before the closure flap 2, since this dir-ty water flows outwardly between the rods 15 along the arrows P1 via the run-o*f openings 9.
Figure 2 shows the fuel tank closure according to Figure 1 in top view. In particular, one can recognize therefrom the ~¦ guide tube 5 with its reduced-scale section 5a, the stop 5b and ¦ 15 the inlet openings 7. The housing 8, which is provided with the run-off openings 9, exhibits (left in the drawing) a projection 11, which has a straight edge.
Figure 3 shows the fuel tank closure with a fuel refueling nozzle 4 inserted therein. The refueling nozzle 4 exhibits a standard ring collar 4a, in the under side of which are located openings 19 for a gas-suck-off system. By means of the ring collar 4a of the refueling nozzle 4, which strikes against the ; stop 5b of the guide tube 5, the guide tube 5 is displaced ayainst the operation of the spring 17 in the direction of the pour-in opening 3. The lower edge of the guide tube exhibits nevertheles= a suf~icient distance with respect to the ori~ice '1 ; opening, so that the exit opening 6 is preserved. By means of the resultant axial displacement of the guide tube 5 in the direction of the pour-in opening 3, the packing 10 (which is arranged on the plank 18) reaches the rim of the pour-in ' 5 opening, and lies against this sealingly, so that the path to j the run-off openings g is blocked.
As is also to be recognized in Figure 3, the closure flap 2 is pushed into the open position against the operation of the torsion spring (not shown) by means of the refueling nozæle 4.
,10 As is to be recognized further in Figure 3, the ring collar l 4a grabs behind the projection 11, so that the ring collar is I securely held between the stop 5b of the guide tube 54 and the projection 11 during the filling process.
Fuel vapors which are pushed out of the tank during filling j15 of the fuel tank stream along the refueling nozzle 4 through the ~!~, annular gap which remains between the refueling nozzle 4 and the pour-in opening 3 and then proceed between the pegs 15 on the outer side of the guide tube 5. By means of the packing 10, :::
which acts as a guide apparatus, the fuel vapors are prevented from gaining access to the open. Rather, these are led back via the inlet openings 7 into the interior of the guide tube and are sucked off by the openings 19 at the under side of the ring collar 4a of the refueling nozzle 4. By means of the packing it is moreover prevented that air is sucked off via the run~off openings 9 and gain access to the gas suck-off system, which would only be additionally loaded by this "false-air". Rather, ., ,., "I ~
,ltj `~ :
^" f~ J~
there streams at the fuel tank closure practically only vapor from the fuel tank into the suck-off system along the arrows designated by P2.
il By means of the twisted path of the fuel vapors it is ensured that no fuel droplets, at any rate no large droplets, are carried along with the stream. Rather, these are thrown out out of the stream. This is especially significant, if the fuel refueling nozzle 4 has not yet taken up the end position shown in Figure 3, but the orifice rim of the refueling nozzle strikes directly on the closure flap 2 and presses this out of the pour-in opening. At this moment fuel vapors often escape, which have accumulated under pressure in the interior of the fuel tank and carry along the fluid fuel, e.g. fuel which drips out of the refueling nozzle.
In the embodiment described in the Figures the lead-apparatus exists for leading the fuel vapors essentially out of the packing 10, which leads the vapors, which stream out via the ,, outlet openings 6, again back into the guide tube 5 via the openings 7. However, it is also possible to omit the run-off opening 9, especially when it is taken care in another manner that no dirty water gains access to the pour-in opening 3. In this case the packing 10 can also be omitted, whereby the ,~ housing 8 takes over the f'unction of the lead-apparatus.
Having thus described the principles of the invention, ~5 together with several illustrative embodiments thereof, it is to be understood that although specific terms are employed, they ~.~
