Abstract

PURPOSE:To greatly expand a control function by controlling the refrigerating cycle by a signal corresponding to a pressure difference which operates on the front surface and the rear side of a diaphragm. CONSTITUTION:A fluid flows in from an inlet port 20, is spouted into a secondary chamber 2 from a valve seat opening port 22 through a primary chamber 4, and flows toward an outlet part 21. A diaphragm 23 filled with a conductive fluid 24, is provided between a tertiary chamber 25 and the secondary chamber 2, and a controller 31 is controlled by taking out an electric control signal corresponding to a pressure difference which operates on the front surface and the rear side of the diaphragm 23. Accordinglythe refrigerating cycle control function can be greatly expanded.
