    • A fluid control valve having a shape memory alloy spring for moving a valve member between an open position and a closed position is provided. The valve includes a valve assembly cylinder, a valve assembly cap fitted to the cylinder, a fluid inlet and a fluid outlet associated with the cylinder, a first member having a cam follower groove, a second member having a cam operatively associated with the groove, a fluid flow gate associated with one of the members as well as the inlet and the outlet, a return spring associated with one of the members, and the shape memory alloy spring associated with one of the members. The length of the shape memory alloy spring changes in response to changes in temperature. The first member is either a rotating valve or a reciprocating member. The second member is either a reciprocating ring or a rotating valve cylinder.
    • 提供一种具有形状记忆合金弹簧的流体控制阀,用于使阀构件在打开位置和关闭位置之间移动。 所述阀包括阀组件缸,与所述缸配合的阀组件盖,与所述缸关联的流体入口和流体出口,具有凸轮从动件凹槽的第一构件,具有与所述凹槽可操作地关联的凸轮的第二构件, 与所述构件中的一个以及所述入口和所述出口相关联的流体流动闸门,与所述构件中的一个相关联的复位弹簧以及与所述构件中的一个相关联的形状记忆合金弹簧。 形状记忆合金弹簧的长度响应于温度的变化而变化。 第一个构件是旋转阀或往复构件。 第二个部件是往复式环或旋转式气缸。
