Abstract
A device for expanding a refrigerant fluid has a first inlet and a first outlet which are connected by a first refrigerant circulation duct. The first refrigerant circulation duct has an upstream part and a downstream part which parts are placed in communication by a first communication passage. The device also has a second inlet and a second outlet which are connected by a second refrigerant circulation duct. The device regulates an expansion of the refrigerant fluid and has a first needle valve housed inside the upstream part of the first refrigerant flow duct connected by a first connecting rod to a thermostatic sensor in communication with the second refrigerant flow duct that allows or prevents refrigerant fluid from circulating through the first communicating passage. The device also measures the pressure of the refrigerant fluid entering the evaporator (Pse) which pressure measurement is taken at the first outlet.
