Abstract
A shut-off valve for hydrogen tank systems includes a main valve having a reciprocally movable valve member which is formed of one or more pieces and interacts at one end with a valve seat and delimits at another end a control chamber. A control valve has a reciprocally movable control valve piston for opening and closing a housing-side of a control valve seat via which the control chamber can be connected to at least one pressure-regulating region. A solenoid acts on a first armature, which is connected to the control valve piston or forms the control valve piston, and a second armature, which is connected to the valve member of the main valve.

A shut-off valve (1) for hydrogen tank systems, the shut-off valve (1) comprising:
- a main valve (2) having a reciprocally movable valve member (3) which is formed of one or more pieces and interacts at one end with a valve seat (4) and delimits at another end a control chamber (5),
- a control valve (6) having a reciprocally movable control valve piston (7) for opening and closing a housing-side control valve seat (8) via which the control chamber (5) can be connected to at least one pressure-regulating region (9, 10), and
- a solenoid (11) for acting on a first armature (12), which is connected to the control valve piston (7) or forms the control valve piston (7), and a second armature (22), which is connected to the valve member (3) of the main valve (2);
- wherein the control valve piston (7) is biased by a spring force of a spring (13) in a direction of the control valve seat (8), and
- wherein the spring (13) is supported at one end on the valve member (3) of the main valve (2).
