Fuel gas tank and fuel gas tank system
The invention relates to a fuel gas tank ( 1 ) for a fuel gas tank system, said fuel gas tank comprising: a storage volume ( 3 ) which is enclosed by a wall ( 2 ) and can be filled with fuel gas via a tank line ( 4 ) having an integrated tank valve ( 5 ); and a temperature sensor ( 6 ) for sensing the temperature in the fuel gas tank ( 1 ), wherein the temperature sensor ( 6 ) is located outside the storage volume ( 3 ) and thermally connected to the storage volume ( 3 ) via a thermal conductor ( 7 ) projecting into the storage volume ( 3 ). The invention also relates to a fuel gas tank system comprising at least one fuel gas tank ( 1 ) according to the invention.
1 . A fuel gas tank ( 1 ) for a fuel gas tank system, having a storage volume ( 3 ) which is enclosed by a wall ( 2 ) and can be filled with fuel gas via a tank line ( 4 ) with an integrated tank valve ( 5 ), and having a temperature sensor ( 6 ) for sensing the temperature in the fuel gas tank ( 1 ), wherein the temperature sensor ( 6 ) is located outside the storage volume ( 3 ) and is thermally connected to the storage volume ( 3 ) via a thermal conductor ( 7 ) projecting into the storage volume ( 3 ).
2 . The fuel gas tank ( 1 ) according to claim 1 , wherein a section of the thermal conductor ( 7 ) projecting into the storage volume ( 3 ) has an axial length (L) which is measured parallel to a longitudinal axis (A) of the fuel gas tank ( 1 ).
3 . The fuel gas tank ( 1 ) according to claim 1 , wherein the tank line ( 4 ) ends in a pipe ( 8 ) which projects into the storage volume ( 3 ) and forms an outlet opening ( 9 ) for the fuel gas.
4 . The fuel gas tank ( 1 ) according to claim 1 , wherein the tank line ( 4 ), the tank valve ( 5 ), the temperature sensor ( 6 ), and the thermal conductor ( 7 ) form a tank unit ( 10 ) which is inserted into an opening ( 11 ) in the wall ( 2 ).
5 . The fuel gas tank ( 1 ) according to claim 4 , wherein the tank unit ( 10 ) has a section ( 12 ) projecting on an outside beyond the wall ( 2 ), wherein the temperature sensor ( 6 ) is integrated into the section ( 12 ).
6 . The fuel gas tank ( 1 ) according to claim 4 , wherein the tank unit ( 10 ) has a section ( 13 ) with an external thread ( 14 ), via which the tank unit ( 10 ) is screwed into the opening ( 11 ) of the wall ( 2 ).
7 . The fuel gas tank ( 1 ) according to claim 1 , wherein the wall ( 2 ) is circular in cross-section and/or spherically shaped in at least one end section ( 15 ).
8 . A fuel gas tank system, comprising at least one fuel gas tank ( 1 ) according to claim 1 .
9 . The fuel gas tank ( 1 ) according to claim 2 , wherein the thermal conductor ( 7 ) is aligned parallel to the longitudinal axis (A).
10 . The fuel gas tank ( 1 ) according to claim 3 , wherein the pipe ( 8 ) runs parallel to the thermal conductor ( 7 ).
11 . The fuel gas tank ( 1 ) according to claim 4 , wherein the opening ( 11 ) is located centrally in a front of the wall.
