1,197,454. Self-contained generating and supply systems. F. R. SCHNEIDER. 16 Aug., 1967 [17 Aug., 1966; 24 July, 1967], No. 37683/67. Heading H2H. A vehicle powered by an internal combustion. engine which drives a dynamo to supply the electrical system of the vehicle is provided with a unit comprising a change-over switch whereby the engine drives the dynamo at different speeds to generate various voltages to supply high and low voltage apparatus. With the change-over switch in its normal position the engine runs at normal speed to generate a low voltage (say 12 volts) to supply low voltage apparatus connected to a low voltage socket in the unit. With the change-over switch in its other position and a high-voltage apparatus connected to a highvoltage socket in the unit current flow through the high-voltage apparatus will cause operation of a reed-type switch with the subsequent operation of a solenoid valve and vacuum servo associated with the engine manifold whereby the carburetter is set to increase the engine speed and hence the voltage generated by the dynamo is increased (say 110 volts). The dynamo is preferably an A.C. generator with a built-in rectifier and the system may include a field regulator for the generator. The unit may comprise a third socket whereby the generator output may be used for battery charging purposes. The unit may include high and low voltage indicating lamps, an ammeter and a voltmeter and protective fuses. The dynamo may also be arranged to charge the battery associated with the vehicle. |
