Abstract

A method and apparatus for metering fluids, in particular liquid fluids, includes at least one fluid being guided out of at least one fluid reservoir through a closeable valve device in a discharge direction, at least one valve opening in the valve device being closed or opened by a valve closing member in order for the fluid to flow or be prevented from flowing through the valve opening, the opening and closing movement being performed magnetically by moving the valve closing member, which is arranged and moved in the fluid reservoir on an upstream side of the valve opening.

Claims

1. A method for metering fluids, in particular liquid fluids, wherein the at least one fluid is passed in a discharge direction through a closable valve means of at least one fluid reservoir, wherein at least one valve opening of the valve device is closed or opened by means of a valve-closing body to direct the fluid through the valve opening or to block a conducting, wherein the opening and closing is performed by magnetically moving the valve closing body and the valve closing body is placed and moved in the fluid reservoir on an upstream side of the valve opening.

2. The method according to claim 1, wherein the valve closing body is moved by means of at least one magnet, which is arranged spaced apart from the valve closing body cooperating with the magnet, by moving and/or changing the field strength thereof.

3. The method according to claim 1, wherein the valve closing body is moved in a guide or unguided manner.

4. The method according to claim 1, wherein a cyanoacrylate is used as a fluid.

5. A metering device for metering fluids, in particular liquid fluids, having means for carrying out the method according to claim 1, in particular with a fluid reservoir which is adapted to receive the fluids, having at least one closable valve means in an outflow direction, through which the fluid can be conducted, wherein the valve means comprises at least one valve opening, which is closable and openable by means of at least one valve closing body, to direct the fluid through the valve opening or to block passing it therethrough, wherein furthermore at least one magnetic actuator is provided to magnetically move the valve closing body to perform the opening or closing, and the at least one valve closing body is movable and is arranged on an upstream side of the valve port in the fluid reservoir.

6. The metering device according to claim 5, wherein at least one associated magnet spaced apart from the valve closing body is provided, said magnet is movable with regard to the valve closing body and/or is changeably designed at least in relation to its field strength.

7. The metering device according to claim 5, wherein the valve closing body has a guide for being moved in a guided manner and/or is arranged in an unguided movable manner.

8. The metering device according to claim 5, wherein cyanoacrylate is provided as a fluid.

9. The use of a metering device according to claim 1 for metering fluids, especially gaseous and/or liquid fluids, in particular for drip-free dosing.
