Abstract
A multi-way valve, particularly for a refrigerant circuit, includes a housing having a number of inlets and outlets and a chamber with a number of seats respectively associated with an inlet or outlet. The multi-way valve also includes a closing element that can move between the seats and at least one actuator, which is provided in the form of an element made of a shape-memory alloy and capable of being displaced from one of the seats when the closing element is heated. The direction of displacement is transversal to the normal direction of the seat.
