Abstract
An expansion valve for modifying the flow of a refrigerant fluid to provide reliable control of a refrigeration system includes a channel for conveying the refrigerant fluid. The channel has an inlet for accepting the refrigerant fluid and an outlet for exhausting the refrigerant fluid. A heating element is disposed in a path of the fluid and associated with the inlet. Electrical terminals are coupled to the heating element for controlling thermal properties of the heating element to modulate or regulate the flow of the refrigerant fluid through the channel.
