PATENT AS AFRICAN AND MALAGASY 9TH INDUSTRIAL PROPERTY P. 887 Yaounde (Cameroon) NO. 01514 o.cm îpîp.i. 29 January 1965 to 17 hours to requested the O A m P. I (G.P. no. 51,339) by the financial anonymous said: Automotive sKa, residing in France. Delivered 21 July 1969, published at The invention relates to a device for - drives telling improved engine accessory organs internal combustion engine, in particular for vehicle automotive. Internal combustion engines equipping the véhi - an old automobile objects is that only few changes during their development, and particularly in to the driving action of the auxiliary units for operation of the engine. The ventilated - the person operating the radiator for the coolant of the engine, the water pump, the fuel pump and the lubricating pump are driven mechanically by the main engine of the vehicle, using transmission belt or gear. This training mode extremely safe gave heretofore satisfaction with motors whose regular operation has remained relatively low. However, during recent years, the ity - tionnements contributed to large piston engines series, were increasing significantly the rotational speed of these motors which exceeds maintaining frequent 7,000 revolutions per minute. It the result is that the auxiliary members which are driven by the engine crankshaft reach speeds rotation detrimental for them. On the other hand which cannot be contemplated that reduce the speed of these organs using a special reduction, because it is necessary to ensure these auxiliary members a rota - sufficient except at idle and low speed regime, as the claims the use of a vehicle automo - the bile, in order to enable operation of the engine in good conditions. Accordingly, it is not not obtainable in this way use rational of these auxiliary members which have optimum performance for a given speed since large variations in engine speed. Therefore ascertain, for example, that the ventilated - the person operating the pumps and exiting from their performance ranges acceptable carrier at high speeds, this being translated to the pumps by air bubbles and cavitations which seriously to the circu - opera liquids and, in some cases, could adversely affect cooling or lubricating the engine. On the other hand, operating speeds for very electrodeposited - vées engine, power consumption wider eco - both of the drive of the auxiliary units represents a large fraction of the shaft power to up to about the fifth or quarter thereof. Further, it is clear that these speeds are too high auxiliary members generate vibrations and unmatched with the smooth-running currently sought by all manufacturers. These vibrations may also cause premature wear of these organs and loosening or breaking their fasteners. According to the present invention, a device is used for driving auxiliary members independent of the rotation of the internal combustion engine, by providing an electric motor whose speed is constant. This engine powered by the vehicle's electrical circuit, provides the drive for all auxiliary members which can therefore operate a optimum performance for all Why speeds of vehicle engine speed and ensuring correct operation thereof. Outside auxiliary members mentioned above, can also be used electric motor for driving the fan of the air conditioning device and thus can suppress the small motor ordinarily provided for this purpose. However, the electric motor is operated continuously, it has been necessary to provide a clutch device controlled by a thermostat between the engine and the radiator fan to drive it, only when it is required by the temperature of the cooling liquid circulating in the radiator. The fan of the air conditioner also includes a manually controlled clutch, electromagnetic or thermostatic, and can be engaged to the request of the vehicle passengers, or depending on the temperature prevailing in the latter. According to the invention, the auxiliary aggregates are driven by at Other advantageous features of the invention shall become apparent from the following description of one 1,096,721. Driving motor vehicle auxiliaries. SIMCA AUTOMOBILES. Jan. 29, 1965 [Jan. 30, 1964], No. 4137/65. Heading B7H. [Also in Division F1] Means for driving the auxiliaries of a motor vehicle engine comprise an electric motor 2 which is energized through a circuit fed by an enginedriven dynamo or alternator so as to operate at substantially constant speed and drives a radiator cooling fan 6 through a clutch 8 actuated by a thermostat responsive to the coolant temperature. The clutch 8, a water pump 4, fuel pump 10 and oil pump 11 are driven from the motor shaft 9 through respective couplings 28, 27, 30, or may be driven by chain, gear or belt drive. An air-conditioning unit 13 includes a fan driven through a coupling 31 and a clutch 14 which is controlled through linkage 25 from the dashboard 26 or by electromagnetic or thermostatic means. The auxiliary aggregates are driven 1° by at least an electric motor powered by the vehicle's electrical circuit and operating continuously at a constant rate, independently of the internal combustion engine. 2 The auxiliary aggregates are driven in series by the electric motor. The auxiliary aggregates are 3° driven by the electric motor via a gearbox. 4 The radiator fan is driven through a clutch member controlled by a thermostat responsive to temperature of the cooling liquid. The fan of the air conditioner is 5° driven through a clutch member to manual control. The fan of the air conditioner is 6° driven through a clutch member to automatic control.
