Abstract
A valve assembly for a fuel pressure vessel system includes: a fuel line; a shutoff valve at the fuel line, which shutoff valve is to be manually actuated; a discharge opening fluidically connected to the fuel line; and a closure element. The shutoff valve is designed to prevent a movement of the closure element from a first position, in which the closure element closes the discharge opening, into a second position, in which the closure element allows flow through the discharge opening, when the shutoff valve is in its open position. The shutoff valve is designed to allow the movement of the closure element from the first position into the second position when the shutoff valve is its closed position, in which the shutoff valve closes the fuel line.

A valve assembly for a fuel pressure vessel system, comprising:
- a fuel line;
- a manually actuated shut-off valve on the fuel line;
- a drainage opening connected to the fuel line in a fluid-conducting manner;
- and
- a closure element configured as a screw closure,
- wherein the shut-off valve is configured so as to prevent a movement of the closure element from a first position, in which the closure element closes the drainage opening, into a second position, in which the closure element releases a through-flow through the drainage opening, when the shut-off valve is in an open position, and
- wherein the shut-off valve is configured so as to allow the movement of the closure element from the first position into the second position when the shut-off valve is in a closed position closing the fuel line.
A method for draining fuel from a valve assembly having
- a fuel line;
- a manually actuated shut-off valve on the fuel line;
- a drainage opening connected to the fuel line in a fluid-conducting manner;
- and
- a closure element designed as a screw closure,
- wherein the shut-off valve is configured so as to prevent a movement of the closure element from a first position, in which the closure element closes the drainage opening, into a second position, in which the closure element releases a through-flow through the drainage opening, when the shut-off valve is in an open position, and
- wherein the shut-off valve is configured so as to allow the movement of the closure element from the first position into the second position when the shut-off valve is in a closed position closing the fuel line,
- the method comprising the steps of:
- closing the fuel line via the shut-off valve so that the shut-off valve is in the closed position;
- and
- moving the closure element from the first position into the second position.
