20090194727 | VALVE ACTUATOR ASSEMBLY - An actuator assembly for actuating a valve includes an extensible bellow having an open end and a closed end, a stem operable to contact the closed end and to actuate a stopper mechanism, and a driver configured to move the bellow. The movement of the bellow effects movement of the stem to actuate the valve. In one embodiment, the driver acts to compress the bellow, the compression causing movement of the stem to open the valve. The bellow may be hermetically sealed to the valve housing, thereby allowing a higher range of fluid pressures. | 08-06-2009 |

20150354719 | SHAPE MEMORY ALLOY ACTUATOR FOR VALVE FOR A VAPOUR COMPRESSION SYSTEM - 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. | 12-10-2015 |
