ABSTRACT:
An improved friction heat generator of the type having stationary and rotatable friction disc assemblies with a thin fluid film there between, driven by either a variable or constant power source. In either case, the disc interface pressure, which is perpendicular to the disc surfaces, is hydraulically regulated by an oil pump so that it is proportional to the rate of rotation of the generator's drive shaft. The heat generator incorporates an air compressor, to convert driving power energy into compressed air energy when the driving power is below the threshold level required to generate a useful quantity of heat output. The compressed air is stored in a storage cylinder. Hydraulic means are provided to deactivate air compression while the driving power energy is at or above the threshold level required to generate a useful quantity of heat output. Heating chambers are within each disc assembly. Heat transfer fluid is circulated so that it must pass through the heating chambers of each disc assembly. The rate of circulation of the heat transfer fluid is regulated so that it is proportional to the quantity of heat being generated in the heating chambers.
