#CMT# #/CMT# The device (12) has a body defining main and secondary paths (T1, T2) for refrigerant e.g. R134a fluid, where the main path comprises an orifice (120) controlled by a needle valve (124). The body has a bulb (125) filled with control fluid and exerts force, relative to pressure of the fluid, on the valve. The body has a spring system (128) e.g. helical spring, exerting spring force opposite to that of the bulb on the valve. A force regulator (181) e.g. additional bulb, regulates the spring force based on operating parameters e.g. temperature, of the refrigerant in an inlet of the main path. #CMT#USE : #/CMT# Triggering device i.e. thermostatic valve, for being installed in an air-conditioning circuit (claimed) of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The configuration of the regulator permits regulation of the overheating of an evaporator of the air-conditioning circuit, and improves performance co-efficient of the triggering device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a thermostatic triggering valve comprising a force regulator.
