Portable DC power generator with constant voltage
First Claim
1. A portable apparatus for delivering constant DC power in vehicles, on boats, and in the field, comprising:
- a base plate having a first plurality of cushioning means having elastomeric mounting means for placement upon a substantially flat horizontal surface;
a permanent magnet DC generator, having armature means and commutation means, disposed upon said base plate at one end thereof;
a fluid-powered internal combustion engine disposed at the other opposite end of said base plate and interconnected with said permanent magnet DC generator via a crankshaft disposed parallel to said base plate, so that DC power is generated by said permanent magnet generator when said fluid-powered internal combustion engine is running;
flexible coupling means for coupling said permanent magnet generator with said crankshaft means;
said fluid-powered internal combustion engine having;
a fuel tank means with a first tank for providing fuel for running said internal combustion engine, a carburetor for mixing said fuel with ambient air, a starter for starting operation of said internal combustion engine, a combustion chamber for combusting said mixed fuel, an exhaust means for venting gases into the ambient, a muffler for minimizing noise generated during operation thereof, and a second plurality of cushioning means having elastomeric mounting means for placement upon said substantially flat surface;
semiconductor circuit governor means having a plurality of Zener diodes and capacitor means electrically interconnected with said DC generator for limiting the RPM output of said internal combustion engine to control, in turn, the voltage output from said permanent magnet generator;
a heat exchanger fixedly attached to said permanent magnet generator and having a fin assembly with a plurality of fins for dissipating heat created incident to said internal combustion engine running and generating power from said permanent magnet generator; and
port means for electrically connecting external appliance means for using said generated DC power.

Abstract
An apparatus for generating a constant source of electrical power in remote locations in the field for use while camping or hunting, in vehicles, on water craft, or for providing power during emergencies due to power failures, accidents, storms, or natural catastrophies. A safely and efficiently operating power generator that makes a minimal intrusion upon the environment is provided comprising a low horsepower gasoline-powered engine which drives a permanent magnet 12-volt AC/DC generator having a built-in electronic governor circuit for sustaining a constant DC output. Constructed with a flexible coupling between the gasoline-powered engine and the generator, and a suitably sized resonator and inherent governor circuit, the invention affords a constant output and quiet operation for use in vehicles, on water craft, and in the field to provide electricity for illumination or for operating common 12-volt appliances.
