Abstract: A valve element can selectively seal or open two ports. The valve element includes a base plate, first and second actuators operated by SMA wires to selectively move sealing elements via deflection of return elements such as leaf springs. The valve element can used in a lift elements or actuators in components of vehicles.

Abstract: Multi-stable SMA actuator comprising two shape memory alloy wires (1, 2) in antagonistic configuration that allow to define multiple stable positions of a movable element (12), said positions being maintained by movable stoppers to lock the movable element, that do not require power and are disengaged by the shape memory alloy wires (1, 2) upon actuation thereof.

Abstract: The present invention is inherent to a shape memory alloy actuated fluidic subassembly (10) and to an equipment incorporating it as dispensing device, wherein actuation of the shape memory alloy wires (16, 16?) causes a fluid-tight reservoir (17?) to e compressed by a lid (18) so as to reduce its volume from a maximum volume Vo to a minimum volume V1, this reduction resulting in a pressure increase that causes the opening of an outlet flap (13?) and the dispensing of a fluid through an outlet channel (13).

Abstract: A valve includes a housing enclosing a pressure chamber. At least one media opening is closeable via a valve element activated by a wire-shaped SMA element connected at its ends to a printed circuit board and at its middle to the valve element. The wire-shaped SMA element extends in a plane parallel to a direction of movement of the valve element.

Abstract: The connection refers to a connecting arrangement with a crimp connector (2) and a wire (3) fixed in place to the crimp connector. The crimp connector encompasses two clamping plates (4, 5) executed as one piece that, in a mounted state, clamp the wire (3) between them and while doing, so fix the wire (3) firmly in place with a force acting in longitudinal axial load direction (B). At least in the mounted state, the inner surfaces of the clamping plates face one another and are at least partially executed as level clamping surfaces (4a, 5a). In the mounted state, the clamping surfaces (4a, 5a) of the clamping plates (4, 5) make contact with one another, whereby an area of the wire section (3?) is pressed partially inside the one clamping plate and partially inside the other clamping plate (4, 5).
