ABSTRACT:
An oil heater particularly adapted to burning waste oil, having oil flow control apparatus providing substantially constant flow of oil to the vaporizer pan without regard to the viscosity of the oil being burned. The flow control apparatus utilizes a piston pump having relatively large input and output orifices, and is driven by a thermostatically controlled constant speed, reversible direction electric motor. Means are provided to transmit the power from the motor to the piston pump such that rotation of the motor in one direction provides a long pump stroke and high volume rate, whereas rotation of the motor in the opposite direction provides a short piston stroke and low volume rate of pumping to provide minimal oil flow to the vaporizer pan to allow combustion to be maintained in the heater.
