Abstract: The invention relates to an actuator for a valve in a refrigeration system. The invention also relates to a valve with such actuator, and to a refrigeration system with such valve. The actuator comprises an elongated Shape Memory Alloy (SMA) element extending along two or more string-like extensions from a distant end to a proximate end in relation to a valve element of a valve. The SMA element, when forming part of the valve, may extend from the distant end to the proximate end connected to a housing of the SMA element, however, electrically insulated from the housing. An encapsulation may provide a thermal resistance, a thermal conductor and/or an electrical resistance between the SMA element and other elements or the surroundings of the SMA element.

Abstract: A magnetic valve (1) comprising a valve housing (2) defining an inlet opening (3) and an outlet opening (4), a valve seat (11), a valve closing element, and an armature tube (7) is disclosed. A piston (6) is arranged movably inside the armature tube (7), said piston (6) being connected to the valve closing element, and an armature (5) is arranged movably at least partly inside the piston (6). A coil (9) is arranged externally to the armature tube (7) in such a manner that at least a part of the armature (5) arranged inside the piston (6) is arranged inside the windings of the coil (9).

Abstract translation: 本发明涉及一种用于制冷系统中的阀的致动器。 本发明还涉及具有这种致动器的阀以及具有这种阀的制冷系统。 致动器包括细长的形状记忆合金（SMA）元件，其沿着两个或更多个线状延伸部延伸，从远端到相对于阀的阀元件的近端。 当形成阀的一部分时，SMA元件可以从远端延伸到连接到SMA元件的壳体的近端，然而，该元件与壳体电绝缘。 封装可以在SMA元件和SMA元件的其它元件或周围之间提供热阻，热导体和/或电阻。
