Definitions

• the present patent request refers to a system especially designed and developed to afford practical features which result in great advantages both with regard to utilisation and also to manufacture. Furthermore, this request also has the objective of presenting a compressor actuating system for vehicle air-conditioning units not only at a low cost for industrial feasibility, but also offering robust features as well as safety and practical use characteristics, thus providing the consumers with an additional option in the market.
• this innovative device allows the motorist to obtain an excellent efficiency level. Moreover, this actuating device for compressors of air-conditioning units of vehicles possesses a good durability. It was conceived to be used chiefly in automotive vehicles.
• the configuration of the device in its new constructional form, comprises a system that is provided with a hydraulic pump, ducts, hoses, condenser, compressor, buttons, thermostat and a refrigerant tank.
• Drawing 1 - shows a view of the complete system of the hydraulic steering integrated with the air-conditioning unit.
• a hydraulic motor (1) which is actuated by the pressure discharged from the ducts (2) connected to the hydraulic pump of the steering system (3); a conventional compressor (4) for vehicle air-conditioning systems, which is actuated by the hydraulic motor (1); a conventional condenser (5) for vehicle air-conditioning systems; a thermostat (6) to adjusts the desired temperature inside the vehicle.
• a further advantage is that this new method utilises a small hydraulic motor, which in turn is actuated by the excess oil pressure generated by the pump of the hydraulic steering system, which is systematically purged tlirough relief valves and this, in fact, is a waste of power.
• the load on the engine will be smaller and consequently its power will increase. This will result in greater economies and improved performance.
