ABSTRACT:
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.
