Abstract
The invention relates to a thermostatic expansion valve assembly for refrigeration units. Condenser pressures are normally five to ten times greater in the summer than in the winter. In the assembly hereof the characterostic adjustment curve is made less dependent on the condenser pressure by reason of having two flow restricting zones in series in which one of the zones has a variable rate closing mode of operation which restricts flow at a constantly increasing rate as the condenser pressure rises.
