A fluid control element comprises a housing, a control chamber ( ) which is formed in the housing and into which at least two flow channels ( &prime;) open, at least one sealing seat ( &prime;) located in the control chamber ( ) and associated with the flow channels, and a sealing and actuation element ( ) arranged in the control chamber ( ) and surrounded by elastic material, which element is pivotally mounted on the housing and can be moved between a closed position, in which it covers a sealing seat ( ) with one of its ends as well as an open position, in which it opens the sealing seat ( ). The sealing and actuation element ( ) forms a two-armed lever ( ) whose pivot mount ( ) is formed by a covering ( ) which is made of elastic material, tightly surrounds the lever ( ) and is clamped between two flat parts ( ) of the housing ( ).

A gas flow valve comprises at least one gas inlet, at least one gas outlet, a flow path between said gas inlet and said gas outlet, a magnetic fluid in the valve arranged in the flow path and means for application of a magnetic field to the magnetic fluid. The magnetic fluid solidifies upon application of the magnetic field, interrupts the flow path from at least one gas inlet to at least one gas outlet gas-tight and permits gas flow when no magnetic field is applied.
