Abstract
A device for the feedback-controllable metering of hydrogen may include: a valve seat; a sealing element; and an electromagnetic actuator having a pole core, a solenoid, and an armature coupled to the sealing element. The actuator moves the sealing element along an axis as a function of an electric current in the solenoid. A surface of the pole core and a surface of the armature conjointly form a double cone.
Claims9
A method for producing a device for the feedback-controllable metering of hydrogen, the method comprising:
- providing a valve seat in a body;
- providing a movable sealing element to seal against the valve seat;
- providing an electromagnetic actuator with a pole core, a solenoid, and an armature coupled to the sealing element, wherein the actuator moves the sealing element along an axis as a function of an electric current in the solenoid;
- wherein the pole core and the solenoid are fixed against movement in relation to the body;
- wherein the actuator is disposed between the pole core and the sealing element;
- and
- attaching a compression spring between the armature and the pole core onto a pin attached in the armature for centering the compression spring;
- wherein a surface of the pole core forms a conical extension having two separate conical profiles and having a cylindrical bore extending from the surface into the pole core;
- the compression spring is disposed within the cylindrical bore of the pole core and the pin extends from the armature into the cylindrical bore of the pole core within the compression spring;
- a surface of the armature forms a conical depression with two separate conical profiles;
- and
- the surface of the pole core and the surface of the armature conjointly form a double cone by interaction of the two respective separate conical profiles.
