Abstract
An electromagnetic valve for a pressure container and which includes a manual shut-off of the valve, a stop, and an electromagnetic shut-off of the valve with a sealing element, a magnet coil, a tappet, and a spring element. When the magnet coil has been currentlessly switched and deactivated, the tappet pressed against the sealing element by the spring element presses the sealing element onto a second opening so as to suppress a fluidic connection from the pressure container. Also, when the magnet coil is activated, the tappet can be moved away from the sealing element as far as the stop, such that the fluidic connection can be released.
Claims18
An electromagnetic valve for a pressure container, comprising:
- a first valve shut-off mechanism including a moveable stop configured to manually open and close the electromagnetic valve;
- and
- a second shut-off mechanism configured to electromagnetically open and close the electromagnetic valve, the second shut-off mechanism having a magnet coil, a tappet, a spring element, and a sealing element which is actuated by the stop for movement in a first direction to close an opening that leads to the pressure container, and a second direction to release the opening,
- wherein:
- in a deactivated state of the magnet coil, the tappet is pressed against the sealing element by the spring element to move the sealing element onto the opening which suppresses a fluidic connection from the pressure container,
- in an activated state of the magnet coil, the tappet is moved away from the sealing element as far as the stop so as to release the fluidic connection from the pressure container, and
- the electromagnetic valve is configured to open the opening in the activated state of the magnet coil, in which the tappet is moved by a magnetic force against a resilient force, and the sealing element is entrained by the tappet.
A pressure container comprising:
- an electromagnetic valve having a first valve shut-off mechanism including a moveable stop configured to manually open and close the electromagnetic valve, and a second shut-off mechanism configured electromagnetically open and close the electromagnetic valve, the second shut-off mechanism having a magnet coil, a tappet, a spring element, and a sealing element which is actuated by the stop for movement in a first direction to close an opening that leads to the pressure container, and a second direction to release the opening,
- wherein:
- in a deactivated state of the magnet coil, the tappet is pressed against the sealing element by the spring element to move the sealing element onto the opening which suppresses a fluidic connection from the pressure container,
- in an activated state of the magnet coil, the tappet is moved away from the sealing element as far as the stop so as to release the fluidic connection from the pressure container, and
- the electromagnetic valve is configured to open the opening in the activated state of the magnet coil, in which the tappet is moved by a magnetic force against a resilient force, and the sealing element is entrained by the tappet.
A method for operating an electromagnetic valve in a pressure container, the method comprising:
- shutting off the electromagnetic valve to close an opening in the pressure container by de-energizing a magnet coil, in which a tappet is moved against a sealing element by a resilient force such that the sealing element closes the opening;
- activating the electromagnetic valve to open the opening in the pressure container by energizing the magnet coil, in which the electromagnetic valve is electromagnetically opened by moving the tappet via the magnetic force against the resilient force, such that the sealing element is entrained by the tappet to open the opening,
- wherein the electromagnetic valve is configured to be:
- closed manually such that a stop part of the electromagnetic valve is moved in a first direction to move the sealing element forward and close the opening;
- and
- opened manually such that the stop part is moved in a second direction to move the sealing element away from and open the opening.
