Abstract
A pump utilizing a shape memory alloy member which is connected to electric terminals to be contracted by the supply of electric power for lowering a piston, the piston mounted to slidably move within a cylinder to thereby introduce a fluid into the cylinder is raised by a biasing force of a bias spring to externally discharge the fluid introduced in the cylinder. The pump has a simple structure which is light and easily repaired and maintained.
