## Abstract

The invention relates to a tank valve (4) for installation at a pressure gas tank (3), having a base body (5), including a first base body section (5.1), which in the assembled state projects into the pressure gas tank (3) and is sealingly connected with the same, and which includes a second base body section (5.2), which in the assembled state remains outside the pressure gas tank (3), further having a plurality of functional sub-groups (9, 11, 12, 13, 14, 16, 17, 22, 23, 26, 27) for refueling the pressure gas tank (3) via a refueling path, for the extraction of gas from the pressure gas tank (3) via an extraction path and for implementing safety and operating functions, at least some of the functional sub-groups (9, 11, 12, 13, 14, 16, 17, 22, 23, 26, 27) at least partially being disposed in the base body (5). The tank valve according to the present invention is characterized by the fact that in the first base body section (5.1) or on the side facing the interior of the pressure gas tank (3) functional sub-groups (13, 22, 23, 26, 27) are disposed at the first base body section (5.1).

## Claims

### Claim 1
