A valve with a shape memory alloy based actuator

A single one time use, SMA based valve, that comprises—

• valve's house assembly that is formed with a lengthwise axis, and with an inlet flow opening for passage of gas or liquid into the valve, and outlet flow opening for passage of the gas or the liquid outwards from the valve;
• and
• 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 said inlet flow opening to said outlet flow opening wherein the herein defined valve is a valve of the normally closed type, or enables stopping of said gas or liquid passage from said inlet flow opening to said outlet flow opening, wherein the herein defined valve is a valve of the normally open type;
• and
• an actuating assembly that is suited to be installed inside said valve's house assembly along said lengthwise axis, and that comprises—
• heating up means, and
• actuating component made of material that is SMA and that is given to heating up by said heating up means in a manner that leads to its extending along the lengthwise axis of said house assembly;
• and—
• a hammer component that is suited to transfer the force that said actuating component is exerting, from said instant of heating said actuating component, along said lengthwise axis to said nipple, and to bias said nipple unto a strain in order to sever it off;
• and—
• said hammer component is suited in addition to continue and propel said nipple for shoving and sweeping it away after it being severed off as said;
• and
• wherein said valve is characterized by that—
• said 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 lengthwise axis of said house assembly, and—
• demarcation exists all the time between said gas or liquid to said actuating component.
