ABSTRACT:
The invention proposes a pressure-reducing device designed to be installed in an air conditioning circuit operating with cooling fluid (FR) and including a housing suited to be traversed by cooling fluid under the control of a needle valve (134). The pressure-reducing device moreover includes a bulb (200) filled with a control fluid (FC) exerting a control pressure on a membrane (33) as a function of ambient conditions, the aforementioned membrane being suitable for acting on the needle valve as a function of the control pressure. The bulb is placed in the path of cooling fluid between the outlet of the condenser and the inlet of the pressure-reducing device.
