Valve

The valve (1) has a spiral spring (3) and a shape-memory-alloy spring (4) acting along a main moving direction (10), and engaging at contact surfaces of a piston (2). Acting directions of the springs are opposite. A heating element (5) i.e. PTC-heating element, is arranged in a region of the shape-m...

More Information
Summary:The valve (1) has a spiral spring (3) and a shape-memory-alloy spring (4) acting along a main moving direction (10), and engaging at contact surfaces of a piston (2). Acting directions of the springs are opposite. A heating element (5) i.e. PTC-heating element, is arranged in a region of the shape-memory-alloy spring and/or at a housing (6), and heats the shape-memory-alloy spring. The piston is movably mounted in an interior of the housing. A fluid inlet (7) stays in fluid communication with a fluid outlet (8) over a flow chamber (9) in an interior of the housing.
