Definitions
- the invention relates to a Tankbehellsystem specified in the preamble of claim 1 genus, such as from the CA 2703183 A1 is known.
- the protective cap can be screwed onto a pour spout.
- the protective cap has a venting position, in which the protective cap is not completely sealed to the pouring spout, so that the container can be vented and a differential pressure between the container interior and the atmosphere can be compensated.
- a canister with a pour spout which has a valve.
- the valve In the unused condition of the pour spout, the valve is closed. The valve is opened when the spout is pressed onto the filler neck of a container to be filled. In this case, a vent valve of the pouring spout is opened.
- the invention has for its object to provide a tank filling system of the generic type, which causes a reliable and safe ventilation when opening the cap in a simple manner.
- valve when adjusting the cap from the end position to the open position forcibly at least temporarily in the venting position.
- bleeding always takes place via the passage released by the valve.
- the protective cap In the end position, the protective cap at least partially covers the pouring spout, so that the protective cap at least partially protects the pouring spout from damage, for example by mechanical action.
- the protective cap in the end position completely covers the valve. As a result, the valve is protected in the end position of the cap from damage and contamination.
- the valve comprises a closure part.
- at least one actuating element is arranged on the protective cap.
- the actuating element advantageously forces the closure part, at least temporarily, forcibly and changes the valve position.
- a forced venting of the liquid container when opening the protective cap can be achieved in a simple manner.
- the positive guide comprises a guide portion and a sliding link.
- the protective cap can be adjusted safely in a structurally simple manner in the venting position.
- the cap rotates when moving from the end position to the open position. Due to the sliding link, a lifting movement of the protective cap is predetermined as a function of the rotational movement of the protective cap. Due to the lifting movement, the actuator forcibly actuates the closure member, and venting takes place.
- the closure part is spring-mounted, wherein the spring force presses the valve in the closed valve position. This ensures that when the valve is not actuated, the passage is not released and no fluid, namely no gases and / or liquids can escape.
- the cap rotates when adjusting from the end position to the open position about an axis of rotation, wherein the sliding link moves with a rotation of the cap around the axis of rotation of the protective cap in the direction of the axis of rotation, and in particular performs a venting stroke.
- the actuating element actuates the closure part at least temporarily in the direction of the axis of rotation, in particular against the spring force.
- the valve is in the open position of the protective cap and in the end position of the protective cap in the closed valve position.
- fluid can not escape either in the open position or in the end position of the protective cap.
- at least one locking device is arranged on the pouring spout, wherein the protective cap locked in the end position with the locking device.
- the protective cap sits comparatively firmly in the end position on the pouring spout, so that an accidental adjustment of the protective cap, in particular an accidental venting and thus releasing the passage, is prevented.
- the protective cap which at least partially covers the pouring spout in the end position, sits firmly on the pour spout and protects it reliably and reliably against damage.
- the cap is at least partially elastic, and the cap is brought by at least partially elastic deformation without compulsory venting of the removed position in the end position.
- This may cause the protective cap be attached relatively quickly to the pour spout. Since the protective cap is usually plugged onto the pour spout after a refueling operation, and venting usually takes place during the refueling process, venting is unnecessary when placing the protective cap on the pour spout. Therefore, it is sufficient to bring the protective cap without forced venting in the end position.
- the guide profile is arranged on an elastic arm fixed to the protective cap.
- the arm deforms elastically at least once when the protective cap is brought from the detached position to the end position. Since the arm formed on the protective cap is elastic, the protective cap can be made inelastic outside the elastic arm, so that a good mechanical protection for the pouring spout is ensured in the end position.
- a first stop is arranged on the pouring spout, wherein the first stop prevents removal of the protective cap from the end position to the removed position without rotational movement. As a result, the protective cap can not be removed from the end position without forced venting.
- the spout has a fixture for attaching the spout to a liquid container, and the protective cap has means for attachment to the fixture. If the pour spout is not attached to the liquid container, then the protective cap can be fixed to the fastening device. Thereby, the escape of fuel residues from the pour spout can be prevented, and the tank filling system is protected from contamination.
- the fastening device comprises at least one thread, in particular an internal thread, and at least one threaded element is advantageously provided on the protective cap.
- the protective cap with the threaded element can be screwed onto the thread of the fastening device.
- a latching, a plug-in device, a bayonet connection or the like may be provided instead of a thread and a threaded element.
- a second stop is arranged on the pouring spout, which prevents venting in the end position. This is an accidental venting or release the passage in the end position, for example by pressing on the cap prevents.
- At least one wiper lip is advantageously arranged on the protective cap.
- the wiper lip is used in particular for stripping impurities on the pouring spout.
- the wiper lip is advantageously arranged so that it strips off impurities on the pouring spout when the protective cap is moved from the removed position into the end position.
- a first wiper lip is arranged inside the protective cap, so that an automatic stripping of contaminants takes place when the protective cap is adjusted.
- a second wiper lip may be fastened to the outside of the protective cap. An operator can thus remove the impurities on the pouring spout with the protective cap removed.

Der Erfindung liegt die Aufgabe zugrunde, ein Tankbefüllsystem der gattungsgemäßen Art zu schaffen, welches beim Öffnen der Schutzkappe auf einfache Weise eine zuverlässige und sichere Entlüftung bewirkt.The invention has for its object to provide a tank filling system of the generic type, which causes a reliable and safe ventilation when opening the cap in a simple manner.
Diese Aufgabe wird durch ein Tankbefüllsystem mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a tank filling system with the features of
Es ist vorgesehen, dass das Ventil beim Verstellen der Schutzkappe von der Endstellung in die geöffnete Position zwangsweise mindestens vorübergehend in Entlüftungsstellung steht. Dadurch findet beim Verstellen von der Endstellung in die geöffnete Position immer ein Entlüften über den vom Ventil freigegebenen Durchlass statt. Durch die Funktionstrennung von Ventil zur Entlüftung und Schutzkappe als Schutz des Ausgießstutzens vor Beschädigung und insbesondere als Betätigungsmittel, welches die Schutzkappe beim Verstellen von der Endstellung in die geöffnete Position zwangsweise betätigt, findet ein zuverlässiges und sicheres Entlüften auch bei einem vergleichsweise hohen Differenzdruck statt. Es erfolgt beim Verstellen der Schutzkappe von der Endstellung in die geöffnete Position eine automatische Entlüftung.It is envisaged that the valve when adjusting the cap from the end position to the open position forcibly at least temporarily in the venting position. As a result, when adjusting from the end position to the open position, bleeding always takes place via the passage released by the valve. Due to the separation of functions of valve for venting and protective cap as protection of the pouring spout from damage and especially as an actuating means which forcibly actuates the protective cap when adjusting from the end position to the open position, a reliable and safe venting takes place even at a comparatively high differential pressure. There is an automatic venting when adjusting the cap from the end position to the open position.
In der Endstellung deckt die Schutzkappe den Ausgießstutzen mindestens teilweise ab, so dass die Schutzkappe den Ausgießstutzen mindestens teilweise vor Beschädigungen, beispielsweise durch eine mechanische Einwirkung, schützt. Vorteilhaft deckt die Schutzkappe in Endstellung das Ventil vollständig ab. Dadurch ist das Ventil in Endstellung der Schutzkappe vor Beschädigungen und Verschmutzung geschützt.In the end position, the protective cap at least partially covers the pouring spout, so that the protective cap at least partially protects the pouring spout from damage, for example by mechanical action. Advantageously, the protective cap in the end position completely covers the valve. As a result, the valve is protected in the end position of the cap from damage and contamination.
Vorteilhaft umfasst das Ventil ein Verschlussteil. Vorteilhaft ist an der Schutzkappe mindestens ein Betätigungselement angeordnet. Vorteilhaft betätigt das Betätigungselement beim Verstellen der Schutzkappe von der Endstellung in die geöffnete Position das Verschlussteil mindestens vorübergehend zwangsweise und ändert die Ventilstellung. Dadurch kann auf einfache Weise eine Zwangsentlüftung des Flüssigkeitsbehälters beim Öffnen der Schutzkappe erreicht werden. Zwischen der Schutzkappe und dem Ausgießstutzen wirkt zweckmäßig eine Zwangsführung zur zwangsweisen Betätigung des Verschlussteils, wobei die Zwangsführung einen Führungsabschnitt und eine Verschiebekulisse umfasst. Mittels einer Verschiebekulisse kann die Schutzkappe auf konstruktiv einfache Weise sicher in die Entlüftungsstellung verstellt werden. Vorzugsweise dreht sich die Schutzkappe beim Verstellen von der Endstellung in die geöffnete Position. Durch die Verschiebekulisse wird in Abhängigkeit der Drehbewegung der Schutzkappe eine Hubbewegung der Schutzkappe vorgegeben. Aufgrund der Hubbewegung betätigt das Betätigungselement das Verschlussteil zwangsweise, und eine Entlüftung findet statt.Advantageously, the valve comprises a closure part. Advantageously, at least one actuating element is arranged on the protective cap. When the protective cap is adjusted from the end position to the open position, the actuating element advantageously forces the closure part, at least temporarily, forcibly and changes the valve position. As a result, a forced venting of the liquid container when opening the protective cap can be achieved in a simple manner. Between the protective cap and the pouring spout expediently a forced operation for forced operation of the closure part, wherein the positive guide comprises a guide portion and a sliding link. By means of a sliding link, the protective cap can be adjusted safely in a structurally simple manner in the venting position. Preferably, the cap rotates when moving from the end position to the open position. Due to the sliding link, a lifting movement of the protective cap is predetermined as a function of the rotational movement of the protective cap. Due to the lifting movement, the actuator forcibly actuates the closure member, and venting takes place.
Zweckmäßig ist das Verschlussteil gefedert gelagert, wobei die Federkraft das Ventil in die geschlossene Ventilstellung drückt. Dadurch ist gewährleistet, dass bei unbetätigtem Ventil der Durchlass nicht freigegeben ist und kein Fluid, nämlich keine Gase und/oder keine Flüssigkeiten austreten können.Suitably, the closure part is spring-mounted, wherein the spring force presses the valve in the closed valve position. This ensures that when the valve is not actuated, the passage is not released and no fluid, namely no gases and / or liquids can escape.
Vorteilhaft dreht die Schutzkappe beim Verstellen von der Endstellung in die geöffnete Position um eine Drehachse, wobei die Verschiebekulisse bei einer Drehung der Schutzkappe um die Drehachse die Schutzkappe in Richtung der Drehachse bewegt, und insbesondere einen Entlüftungshub ausführt. Vorteilhaft betätigt das Betätigungselement das Verschlussteil mindestens vorübergehend in Richtung der Drehachse, insbesondere entgegen der Federkraft. Dadurch muss ein Bediener beim Verstellen der Schutzkappe von der Endstellung in die geöffnete Position die Schutzkappe lediglich drehen. Die Hubbewegung der Schutzkappe wird zwangsweise aufgrund der Verschiebekulisse hervorgerufen, so dass eine zwangsweise Betätigung des Ventils und damit eine zwangsweise Entlüftung stattfindet.Advantageously, the cap rotates when adjusting from the end position to the open position about an axis of rotation, wherein the sliding link moves with a rotation of the cap around the axis of rotation of the protective cap in the direction of the axis of rotation, and in particular performs a venting stroke. Advantageously, the actuating element actuates the closure part at least temporarily in the direction of the axis of rotation, in particular against the spring force. As a result, when adjusting the protective cap from the end position to the open position, an operator merely has to turn the protective cap. The lifting movement of the protective cap is forcibly caused due to the Verschiebekulisse, so that a forced operation of the valve and thus a forced venting takes place.
Vorzugsweise steht das Ventil in geöffneter Position der Schutzkappe und in Endstellung der Schutzkappe in geschlossener Ventilstellung. Dadurch kann weder in geöffneter Position noch in Endstellung der Schutzkappe Fluid austreten. Zweckmäßig ist am Ausgießstutzen mindestens eine Rastvorrichtung angeordnet, wobei die Schutzkappe in Endstellung mit der Rastvorrichtung verrastet. Dadurch sitzt die Schutzkappe in Endstellung vergleichsweise fest auf dem Ausgießstutzen, so dass ein versehentliches Verstellen der Schutzkappe, insbesondere ein versehentliches Entlüften und damit Freigeben des Durchlasses, unterbunden ist. Zusätzlich ist gewährleistet, dass die Schutzkappe, die in Endstellung den Ausgießstutzen mindestens teilweise abdeckt, fest auf dem Ausgießstutzen sitzt und diesen sicher und zuverlässig vor Beschädigungen schützt.Preferably, the valve is in the open position of the protective cap and in the end position of the protective cap in the closed valve position. As a result, fluid can not escape either in the open position or in the end position of the protective cap. Appropriately, at least one locking device is arranged on the pouring spout, wherein the protective cap locked in the end position with the locking device. As a result, the protective cap sits comparatively firmly in the end position on the pouring spout, so that an accidental adjustment of the protective cap, in particular an accidental venting and thus releasing the passage, is prevented. In addition, it is ensured that the protective cap, which at least partially covers the pouring spout in the end position, sits firmly on the pour spout and protects it reliably and reliably against damage.
Vorteilhaft ist die Schutzkappe mindestens teilweise elastisch ausgebildet, und die Schutzkappe ist durch mindestens teilweise elastische Verformung ohne zwangsweises Entlüften von der abgenommenen Position in die Endstellung bringbar. Dadurch kann die Schutzkappe vergleichsweise schnell auf den Ausgießstutzen aufgesteckt werden. Da die Schutzkappe üblicherweise nach einem Tankvorgang auf den Ausgießstutzen aufgesteckt wird, und beim Tankvorgang üblicherweise eine Entlüftung stattfindet, ist eine Entlüftung beim Aufsetzen der Schutzkappe auf den Ausgießstutzen nicht erforderlich. Daher genügt es, die Schutzkappe ohne zwangsweises Entlüften in die Endstellung zu bringen.Advantageously, the cap is at least partially elastic, and the cap is brought by at least partially elastic deformation without compulsory venting of the removed position in the end position. This may cause the protective cap be attached relatively quickly to the pour spout. Since the protective cap is usually plugged onto the pour spout after a refueling operation, and venting usually takes place during the refueling process, venting is unnecessary when placing the protective cap on the pour spout. Therefore, it is sufficient to bring the protective cap without forced venting in the end position.
Vorzugsweise ist das Führungsprofil an einem an der Schutzkappe festgelegten elastischen Arm angeordnet. Vorzugsweise verformt sich der Arm mindestens einmal elastisch, wenn die Schutzkappe von der abgenommenen Position in die Endstellung gebracht wird. Da der an der Schutzkappe ausgebildete Arm elastisch ist, kann die Schutzkappe außerhalb des elastischen Arms unelastisch ausgebildet sein, so dass in Endstellung ein guter mechanischer Schutz für den Ausgießstutzen gewährleistet ist. Zweckmäßig ist am Ausgießstutzen ein erster Anschlag angeordnet, wobei der erste Anschlag ein Abnehmen der Schutzkappe von der Endstellung in die abgenommene Position ohne Drehbewegung unterbindet. Dadurch kann die Schutzkappe aus der Endstellung nicht ohne zwangsweises Entlüften abgenommen werden.Preferably, the guide profile is arranged on an elastic arm fixed to the protective cap. Preferably, the arm deforms elastically at least once when the protective cap is brought from the detached position to the end position. Since the arm formed on the protective cap is elastic, the protective cap can be made inelastic outside the elastic arm, so that a good mechanical protection for the pouring spout is ensured in the end position. Appropriately, a first stop is arranged on the pouring spout, wherein the first stop prevents removal of the protective cap from the end position to the removed position without rotational movement. As a result, the protective cap can not be removed from the end position without forced venting.
Vorteilhaft besitzt der Ausgießstutzen eine Befestigungsvorrichtung zum Befestigen des Ausgießstutzens an einem Flüssigkeitsbehälter, und die Schutzkappe besitzt Mittel zur Befestigung an der Befestigungsvorrichtung. Ist der Ausgießstutzen nicht am Flüssigkeitsbehälter befestigt, so kann die Schutzkappe an der Befestigungsvorrichtung festgelegt werden. Dadurch kann das Austreten von Kraftstoffresten aus dem Ausgießstutzen verhindert werden, und das Tankbefüllsystem ist vor Verschmutzungen geschützt. Vorteilhaft umfasst die Befestigungsvorrichtung mindestens ein Gewinde, insbesondere ein Innengewinde, und an der Schutzkappe ist vorteilhaft mindestens ein Gewindeelement vorgesehen. Vorteilhaft ist die Schutzkappe mit dem Gewindeelement auf das Gewinde der Befestigungsvorrichtung aufschraubbar. Anstelle eines Gewindes und eines Gewindeelements kann jedoch auch eine Verrastung, eine Steckvorrichtung, eine Bajonettverbindung oder dergleichen vorgesehen sein. Vorzugsweise ist am Ausgießstutzen ein zweiter Anschlag angeordnet, der ein Entlüften in Endstellung verhindert. Dadurch ist ein versehentliches Entlüften bzw. Freigeben des Durchlasses in Endstellung, beispielsweise durch Drücken auf die Schutzkappe, verhindert.Advantageously, the spout has a fixture for attaching the spout to a liquid container, and the protective cap has means for attachment to the fixture. If the pour spout is not attached to the liquid container, then the protective cap can be fixed to the fastening device. Thereby, the escape of fuel residues from the pour spout can be prevented, and the tank filling system is protected from contamination. Advantageously, the fastening device comprises at least one thread, in particular an internal thread, and at least one threaded element is advantageously provided on the protective cap. Advantageously, the protective cap with the threaded element can be screwed onto the thread of the fastening device. However, instead of a thread and a threaded element, a latching, a plug-in device, a bayonet connection or the like may be provided. Preferably, a second stop is arranged on the pouring spout, which prevents venting in the end position. This is an accidental venting or release the passage in the end position, for example by pressing on the cap prevents.
Vorteilhaft ist an der Schutzkappe mindestens eine Abstreiflippe angeordnet. Die Abstreiflippe dient insbesondere zum Abstreifen von Verunreinigungen am Ausgießstutzen. Die Abstreiflippe ist vorteilhaft so angeordnet, dass sie beim Verstellen der Schutzkappe von der abgenommenen Position in die Endstellung Verunreinigungen am Ausgießstutzen abstreift. Vorzugsweise ist eine erste Abstreiflippe innerhalb der Schutzkappe angeordnet, so dass beim Verstellen der Schutzkappe ein automatisches Abstreifen von Verunreinigungen stattfindet. Alternativ oder zusätzlich kann eine zweite Abstreiflippe außen an der Schutzkappe befestigt sein. Ein Bediener kann damit die Verunreinigungen am Ausgießstutzen bei abgenommener Schutzkappe abstreifen.At least one wiper lip is advantageously arranged on the protective cap. The wiper lip is used in particular for stripping impurities on the pouring spout. The wiper lip is advantageously arranged so that it strips off impurities on the pouring spout when the protective cap is moved from the removed position into the end position. Preferably, a first wiper lip is arranged inside the protective cap, so that an automatic stripping of contaminants takes place when the protective cap is adjusted. Alternatively or additionally, a second wiper lip may be fastened to the outside of the protective cap. An operator can thus remove the impurities on the pouring spout with the protective cap removed.
