Expansion valve unit for refrigeration circuit has pressure sensor at one end of refrigeration control expansion valve for determining pressure of coolant passing along coolant path

摘要

The device has a refrigeration control expansion valve (5) in the flow path of a coolant fed into a cooling system evaporator, a pressure sensor (6) at one end of the valve for determining the pressure of the coolant passing along the coolant path, connectors (8a,44), a hermetic seal (6a) at the joint between the valve and sensor and a hermetically sealed volume (8b) in a block (8) forming the base body of the valve.
