Abstract: An air conditioning system for motor-vehicles includes a thermally controlled expansion valve unit for regulating the expansion of the fluid upstream of the evaporator, depending upon the temperature downstream of the evaporator. An intermediate heat exchanger provides a heat exchange between the conduit upstream of the evaporator and the conduit downstream of the evaporator. The expansion valve unit is arranged in such a way that its temperature sensor detects a temperature of the fluid along the conduit downstream of the evaporator at a portion of this conduit which is located downstream also with respect to the intermediate heat exchanger. A connecting flange is interposed between the evaporator and the thermally controlled expansion valve unit.

Abstract: A motor-vehicle is provided with an auxiliary cooling system, having a low temperature cooling liquid, entirely independent from the cooling circuit of the engine and including a radiator located at the front part of the motor-vehicle facing the radiator of the cooling circuit of the engine. The auxiliary cooling circuit comprises one or more auxiliary radiators which are connected parallel to the radiator of the auxiliary circuit and which are constituted by motor-vehicle body components.

Abstract: A control assembly for regulating a number of functions, -and particularly for a vehicle, has a control/selection device enabling a user to select any one of the functions, and a knob which is rotated manually to regulate the selected function; the control assembly also has a motor for exerting a rotation-resisting torque on the knob, and a memory containing a number of different memorized profiles, each associated with a relative vehicle function and indicating a relative pattern of the resisting torque, depending on the angular position of the knob; a central control unit controls the motor to exert on the knob a resisting torque corresponding to the memorized profile associated with the selected function; the control/selection device extends along the axis of the knob, and may be of different types, e.g. a “track-ball”, joystick, or sensor pad; and a number of control/selection keys (30) are arranged about the knob.
