ABSTRACT:
In an automobile air conditioning system, an improved orifice type expansion device includes a movable piston which supports an orifice tube so that the piston is moved in response to higher than normal condenser pressure towards a stationary plug member so that the resistance to flow is increased and thus a desirable low evaporator pressure and temperature is maintained.
