Patent ID: 7222495

Claim:
A device for cooling and depolluting a motor vehicle, which is intended for air-conditioning the passenger compartment of said vehicle and for cooling its engine block ( 22 ), and the elements of which are connected by a main tube ( 25 ) containing an antifreeze fluid, comprising a pump ( 13 ), an absorber ( 23 ), a high-pressure generator ( 19 ), a low-pressure generator ( 4 ), a condenser ( 5 ), an evaporator ( 24 ), characterized in that it comprises a temperature-pressure regulating valve ( 17 ) located downstream of the engine block ( 22 ), for maintaining a constant pressure/temperature in the part of the cooling circuit around the engine ( 18 ) inside said engine block ( 22 ), thus preventing water from evaporating inside said part of the cooling circuit and making it possible to sustain cooling of said engine block ( 22 ).
