摘要：
A multiple pulse volume shuttle pump powered by a shape memory alloy (SMA) wire is disclosed. In some embodiments, a shuttle pump system may include a pump chamber, a valve operable with the pump chamber, and a wire coupled to a valve shaft of the valve for controlling a position of the valve. The shuttle pump system may further include a pin disposed within an inset pathway of a cam, wherein the pin is moveable between multiple positions of the inset pathway in response to actuation of the valve shaft.
