A expansion-distribution assembly ( 30 ) for simultaneously throttling, mixing, and distributing refrigerant fluid just upstream of a heat-absorbing component (e.g., an evaporator) of a heatpump system. The expansion-distribution assembly ( 30 ) comprises a valve-nozzle adjustment device ( 34 ) which moves a piston ( 52 ) relative to a nozzle chamber ( 44 ) to vary flow-characteristics therethrough. The piston ( 52 ) is moved during operation of the heatpump system (based on, for example, pressure and temperature data) to dynamically customize the valve-nozzle for the current load of the system.
