DETAILED DESCRIPTION OF THE DRAWINGS

[0022] In the figures, elements that are the same or have the same function are provided with the same reference signs.

[0023] FIG. 1 shows a battery housing 1 for a battery of a motor vehicle. The battery housing 1 has housing walls 2, which enclose an interior space 3 for receiving battery cells, not shown here, of the battery. A valve apparatus 4, which is designed to provide an internal pressure reduction of an internal pressure in the internal space 3 of the battery housing 1, is arranged in at least one housing wall 2. In addition, the valve apparatus 4 has a valve seat in the form of a degassing opening 5, which is arranged in one of the housing walls 2. Moreover, the valve apparatus 4 has a valve body 6, which in FIG. 1 is shown in a closed position and seals the degassing opening 5. The valve body 6 is in this instance in the form of a cap-like sealing disk 7 which is arranged on an outer side 8 of the housing wall 2 and in the closed position covers or seals the degassing opening 5, in particular in a gas-tight manner.

[0024] The valve apparatus 4 moreover has a resetting device 9 in the form of a spring 10 and a fixing device 11. The valve body 6 can be moved between the closed position and a first open position, as is shown in FIG. 2, by way of the resetting device 9. In the process, the valve body 6 is moved out of the closed position into the first open position as a result of an internal pressure increase, which results from a pressure difference between the interior space 3 and a surrounding area 12 of the battery housing 1. In this respect, the internal pressure for providing the first open position is between a first threshold value and a second threshold value. To provide the first open position, the valve body 6 is raised with respect to the housing wall 2, and therefore moved away from the degassing opening 5, as a result of the increasing internal pressure counter to a resetting force of the resetting device 9. As a result, it opens up the degassing opening 5 temporarily or reversibly, with the result that it is possible to equalize the pressure between the interior space 3 and the surrounding area 12. As soon as the elevated internal pressure has been reduced and the internal pressure falls below the first threshold value again, the resetting device 9 draws the valve body 6 back to the housing wall 2 and presses it onto the degassing opening 5 again. The valve body 6 is then in the closed position again.

[0025] If the internal pressure increase is an internal pressure increase resulting from a hot gas, which was caused by hot gas of at least one battery cell in the interior space 3 and as a result of which the internal pressure exceeds the second threshold value, the valve body 6 is moved beyond the first open position into a second open position and fixed there by way of the fixing device 11. The second open position is shown in FIG. 3. In this instance, the fixing device 11 is a snap connection device, which comprises two connecting elements 13, 14. Here, one first connecting element 13 is an elastic snap hook 15, which in this instance is arranged on the housing wall 2. One second connecting element 14 is a locking element in the form of an undercut 16, which is arranged on the valve body 6, in this instance on a collar-like region of the cap-like sealing disk 7. So long as the internal pressure is between the first and the second threshold value, a snap hook head 17 of the snap hook 15 glides along the valve body 6, without becoming arranged in the undercut 16 in the process. However, as soon as the internal pressure exceeds the second threshold value, the valve body 6 is raised far enough with respect to the housing wall 2 that the snap hook head 17 becomes arranged in the undercut 16. As a result, the connecting elements 13, 14 snap or latch into one another and fix the valve body 6 in the second open position. In this second open position, the hot gas can escape from the interior space 3 into the surrounding area 12.
