The invention relates to a tank filling system having a protective cap and having a pouring spout. The protective cap has an end position wherein it partially covers the pouring spout, and wherein the protective cap has an opened position wherein it is removable from the pouring spout into a removed position. The pouring spout includes at least one valve, wherein the valve has a venting position and a closed valve position. In the venting position, the valve frees at least one passage for a fluid. In the closed valve position, the valve closes the passage. In the end position of the protective cap, the valve is in the closed valve position. During the adjustment of the protective cap from the end position into the opened position, the valve is forcibly adjusted at least temporarily into the venting position.

1. A tank filling system comprising: a pouring spout;a removable protective cap;said removable protective cap defining an end position and an opened position;said removable protective cap being configured to at least partially cover said pouring spout in said end position;said removable protective cap being configured to be removable from said pouring spout when in said opened position;said pouring spout having a valve;said valve having a venting position and a closed position;a through passage;said valve being configured to clear said through passage for passing a fluid in said venting position thereof and to close said through passage in said closed position;said valve being further configured to be in said closed position thereof when said removable protective cap is in said end position and when said removable protective cap is in said opened position; and,said protective cap forcibly actuates said valve such that said valve is forcibly at least temporarily in said venting position when said removable protective cap is shifted from said end position to said opened position thereof. 2. The tank filling system of claim 1 further comprising: an actuating element arranged on said removable protective cap;said valve including a closure part; and,said actuating element being configured to, at least temporarily, actuate said closure part and change position of said valve when said removable protective cap is shifted from said end position into said opened position thereof. 3. The tank filling system of claim 2 further comprising: a constraining guide acting between said removable protective cap and said pouring spout to compulsorily actuate said closure part; and,said constraining guide including a guide section and a slider. 4. The tank filling system of claim 3, wherein said closure part is resiliently mounted so as to cause a resulting resilient force to press said valve into said closed position thereof. 5. The tank filling system of claim 3, wherein: said removable protective cap rotates around a rotational axis when being shifted from said end position to said opened position;said constraining guide is configured to move in a direction of said rotational axis when said removable protective cap is rotated about said rotational axis; and,said actuating element is configured to at least temporarily actuate said closure part in the direction of said rotational axis. 6. The tank filling system of claim 3 further comprising: an elastic arm fixed on said removable protective cap; and, said guide section being arranged on said elastic arm. 7. The tank filling system of claim 6, said removable protective cap being in a removed position when said removable cap is removed from said pouring spout; wherein said elastic arm elastically deforms at least once when said removable protective cap is moved from said removed position to said end position. 8. The tank filling system of claim 1 further comprising: a latching device arranged on said pouring spout; and,said removable protective cap being configured to latchingly engage said latching device in said end position. 9. The tank filling system of claim 1, wherein: said removable protective cap being in a removed position when said removable cap is removed from said pouring spout;said removable protective cap is at least in part elastic; and,said removable protective cap is configured to be movable from said removed position to said end position through at least partial elastic deformation without forced venting. 10. The tank filling system of claim 1 further comprising: a first stop arranged on said pouring spout; and,said first stop being configured to prevent a removal of said removable protective cap from said end position into the removed position without a rotational movement. 11. The tank filling system of claim 10 further comprising a second stop arranged on said pouring spout and configured to prevent a venting in said end position. 12. The tank filling system of claim 1, wherein: said pouring spout has a fastening arrangement configured to fasten said pouring spout to a liquid container; and,said removable protective cap has a fastener configured to fix said removable protective cap to said fastening arrangement. 13. The tank filling system of claim 1 further comprising at least one wiping lip arranged on said removable protective cap. 14. A tank filling system comprising: a pouring spout;a removable protective cap;said removable protective cap defining an end position and an opened position;said removable protective cap being configured to at least partially cover said pouring spout in said end position;said removable protective cap being configured to be removable from said pouring spout when in said opened position;said pouring spout having a valve;said valve having a venting position and a closed position;a through passage;said valve being configured to clear said through passage for passing a fluid in said venting position thereof and to close said through passage in said closed position;said valve being further configured to be in said closed position thereof when said removable protective cap is in said end position and when said removable protective cap is in said opened position; and,said protective cap forcibly actuates said valve such that said valve is forcibly at least temporarily in said venting position when said removable protective cap is shifted from said end position to said opened position thereof so as to cause said valve to be compulsorily opened during a removal of said removable protective cap from said pouring spout initiated from said end position.
