A refrigerant expansion device outlet port includes a generally annular body defining a flow path between an inlet and an outlet, with a mixing device interposed between the inlet and outlet to promote turbulent mixing of refrigerant as it passes through the port. In one embodiment, the mixing device is a screen inserted between the inlet and the outlet, preferably adjacent the outlet. In a second embodiment, the mixing device is provided as a set of concentric axially spaced annular shoulders formed on an inner circumference of the flow path between the inlet and outlet. In a third embodiment, the flow path includes a series of rifling grooves on an inner circumferential surface of the flow path for inducing turbulent flow. In a fourth embodiment, the flow path is formed from radially offset or mismatching inlet and outlet flow paths.
