Description

technical field

[0001] The invention relates to a valve comprising a housing surrounding a pressure chamber with a first medium opening, wherein a valve element is arranged inside the pressure chamber, which controls the medium opening, ie closes and opens the medium opening . The valve element is actuated by a wire-shaped SMA element. The invention also relates to a valve arrangement comprising a plurality of valves. Background technique

[0002] In the valve known from DE 10 2005 060 217 B4, a circuit board is arranged inside the housing, with which the respective ends of a wire-shaped SMA element are electrically and mechanically connected, the SMA element being actuated in the form of a push rod valve components. At one end thereof, the push rod is guided in an opening of the circuit board in the direction of its longitudinal extension. Due to the space required for the printed circuit board, the housing of the valve is correspondingly bulky, which is disadvantageous...
