A refrigerant expansion device for use in a vapor compression refrigeration system is disclosed. The device has a body portion with a bore extending therethrough. At least that portion of the body portion which forms the bore walls is made of a shape memory alloy which undergoes a metallurgical transformation at a predetermined transformation temperature to change the bore size of the device in response to the temperature of refrigerant flowing through the device. In this manner, the bore size of the device is adjusted in response to different operating conditions of the refrigeration system.
