EVAPORATOR/EXPANSION VALVE UNIT FOR USE IN AUTOMOTIVE AIR CONDITIONING SYSTEM .

摘要

An evaporator/expansion valve unit (100) for use in an automotive air conditioning system, comprises an evaporator (10) which includes first and second parallely extending elongate tanks and a plurality of flat hollow elements (2) mounted on the first and second elongate tanks. The interior of each element is in a fluid communication with the interior of each tank. The first tank is formed with inlet and outlet openings. A block type expansion valve (4) has a first passage which is closed when a spherical valve body abuts against a given part of the first passage against a certain force applied thereto and a second passage which has a temperature sensing means by which the certain force is varied in accordance with the temperature of a refrigerant flowing in the second passage. The first passage has an outlet opening connected to the inlet opening of the first tank.; The second passage has an inlet opening connected to the outlet opening of the first tank. The expansion valve has the first tank directly mounted thereon.
