Vehicular remote power supply system

Claim 1

In a vehicular remote power supply adapted for use with a vehicle electrical system including a direct current voltage source; a dynamo having armature and field terminals; and regulator means having a field terminal, a battery terminal connected with said voltage source, and an armature terminal connected with the dynamo armature terminal, said dynamo being driven by the throttle-controlled internal combustion engine of the vehicle; the improvement which comprises solenoid means (26) including a plunger (32) connected with said throttle and having a normal deenergized position in which said engine is operated at an idling speed, pull-in coil means (28) for displacing said plunger toward an energized position in which said throttle operates said engine at a high running speed, and hold-in coil means (30) for maintaining said plunger in the energized position; means for energizing said solenoid means, including a normally closed plunger-operated pull-in switch (36) for connecting one end of said pull-in coil with said voltage source, and a normally open ground switch (38) connecting the other end of said pull-in coil with ground, said pull-in switch being opened when the plunger is in the fully energized position, said holdin coil being connected in parallel across the series branch including said pull-in switch and said pull-in coil, said holdin coil being operable to maintain the plunger in the energized position when said pull-in switch is opened by said plunger; a first two-position field switch (12) normally having a first position connecting said alternator field terminal with said regulator field terminal, said field switch being operable to a second position to connect said alternator field terminal with said voltage source; a normally closed plunger-operated armature switch (39) normally connecting said alternator armature terminal with said voltage source, said plunger-operated switch also being opened when said plunger is in the energized position; normally deenergized main relay means for closing said ground switch and for operating said first field switch from the first position to the second position; and means for energizing said main relay means, whereby said solenoid means are activated to effect high-engine driving speed and said alternator is operated to supply high direct current voltage at the alternator armature terminal.
