Document Type and Number:
Japanese Patent JP2012519816
Kind Code:
A
Abstract:
This disclosure describes an apparatus having a valve and an elongated shape memory alloy element. The valve has a lever in a first position, whereby the valve is closed. The elongated shape memory alloy element has a first end connected to the lever. The shape memory alloy element has been strained to have a first length, wherein exposure of at least a portion of the shape memory alloy element to a temperature at or exceeding its austenite transformation temperature causes the shape memory alloy element to shorten to a second length, the second length being less than the first length, thereby causing the first end of the shape memory alloy element to pull the lever to a second position, whereby the valve is opened.
