    (54) Refrigerant metering apparatus for multicircuit coil


    (57) In a multicircuit evaporator coil where vaporized refrigerant is conducted simultaneously to a plurality of parallel circuits by way of individual distributor lines (12), provision is made to meter the refrigerant flow within each of the distribution lines (12) by way of individual expansion devices (17) disposed therein. In one embodiment, a cylinder having a central bore (19) formed therein is mounted within each of the distribution lines (12) by way of a brazing process. In another embodiment, the individual distribution lines (12) have contracted portions formed therein for metering the refrigerant in the respective circuits.
