ABSTRACT:
A valve is provided with a valve housing encompassing a pressure chamber and possessing at least two valve ports which open into the pressure chamber, whereby, in the pressure chamber at least one axially slidable valve stem exists, which controls at least one of the valve ports and which the at least one valve stem is movable between a closed position and an open position. The valve further encompasses at least one wire or band shaped SMA element, the element having an SMA, as well as possessing a resetting element for the movement of the valve stems into the closure direction. The valve seat carries on its first end a port closing closure disk, whereby its second end is axially guided within the pressure chamber on a base plate which the plate extends itself transversely to the valve stems.
