ABSTRACT:
The invention relates to a stop valve (1, 1′, 1″) for a portable pressurized-gas container (35). A valve body (2) is provided with three connection adapters (7, 17, 18), i.e. one central connection adapter as a gas tank connection adapter (7), another connection adapter as outlet connection adapter (17) and a third connection adapter as spindle drive receiving adapter (18). Valve body (2) is made in several parts including valve body element (3) with the outlet connection adapter (17) and a spindle drive receiving adapter (18) and a radial valve seat element receiving bore (20) going to the bottom of the spindle drive receiving adapter (18). Furthermore, the valve body (2) has an oblong valve seat element (5) with gas supply bore (29) provided at the one end of the valve seat (30) and a bearing collar (26) on the other end. In its assembled state, the valve seat element (5) is inserted tightly into the radial bolt receiving bore (20). In addition, the valve body (2) has a main bolt (4) which is inserted tightly into the central main bolt receiving bore (19). Suitable gas supply bores (9, 11, 29) allow gas to flow from the connected pressurized-gas container (35) via the spindle drive receiving adapter (13) to the outlet connection adapter (17).
