Abstract: Maintenance apparatus of an air conditioning system mounted on a motor vehicle. The maintenance apparatus comprises: two external ducts, a discharging circuit, which is connected to the ducts to receive the carbon dioxide contained in the air conditioning system at a first pressure and a first flow rate and is structured so as to discharge the carbon dioxide received into the environment, a measuring apparatus, which is configured so as to measure the amount of carbon dioxide that passes through the discharging circuit, and a pressure and flow rate reducing device, which is structured so as to reduce the first pressure and the first flow rate of the carbon dioxide to the be measured to a second predetermined pressure and to a second predetermined flow rate, respectively.

Abstract: An air conditioning recharging machine includes a pair of flexible hoses connected to the air-conditioning system and a recharging assembly to supply a refrigerant fluid to the air-conditioning system through the flexible hoses. The machine has a discharging assembly to discharge the refrigerant fluid from the air-conditioning system and a valve distributor body, which is provided with a series of inlets/outlets hydraulically connected to the flexible hoses, to the recharging assembly and to the discharging assembly. The valve distributor body is in the form of a monobloc made of rigid material which is provided with straight inner through-ducts, each of which extends in the monobloc so as to have the two axial ends which are arranged on two respective faces of said monobloc opposite one to the other, and are each closed by a respective solenoid valve coupled to the face itself.
