    摘要： The electrically operated valve device (10) comprises: - a supporting body (12) having a valve seat; - a shutter (16) which can be moved in a guided way between a first valve seat opening position and a second valve seat closing position; - a sliding member (18) which is mounted movably on the supporting body (12), is fixed mechanically to the shutter (16), and is movable between an opening condition and a closing condition, in which it moves the shutter (16) to the opening and closing position respectively; - a resilient return member (24) associated kinematically with the sliding member (18) and tending to retain the sliding member (18) in the closing condition; - first opening actuators (50) which arc associated with the sliding member (18) and which arc designed to enter an activated condition, in which they bring the sliding member (18) into the opening condition against the action of the resilient return member (24); - a retaining mechanism (28) mounted on the supporting body (12) and capable of retaining the sliding member (18) when the latter is in the opening condition; and - second closing actuators (52) which are associated with the retaining mechanism (28), which can be electrically activated, and which can assume an activated condition in which they release the sliding member (18) from the retaining mechanism (28), allowing this sliding member (18) to return from the opening position to the closing position.

    摘要： A single one time use valve, based on a Shape Memory Alloy (hereinafter—SMA) actuating component, wherein the valve comprises a nipple component given to shearing and shoving from the instant of its being severed off, in a manner that enables passage of the gas or the liquid from the valve's inlet flow opening to the valve's outlet flow opening wherein the valve is a valve of the normally closed type, or enables stopping of said gas or liquid passage from the inlet flow opening to the outlet flow opening, wherein the valve is a valve of the normally open type, and wherein the valve is characterized by that the inlet flow opening and outlet flow opening are formed substantially on at least one plain, that extends in its direction wherein it is substantially orthogonal to the valve's house assembly lengthwise axis and wherein a physical demarcation exists all the time between the gas or liquid to the valve's SMA made actuating component.

    摘要： 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.

    摘要： A frangible diaphragm for use in a valve mechanism, said frangible diaphragm comprising:
    an actuator substance 102 provided in, or on, the frangible diaphragm,
    wherein the actuator substance expands from a smaller volume to a larger volume on application of heat such that a force generated by the expansion causes the diaphragm to fracture.
