Modulating oil fuel delivery system

Abstract

A variable flow rate oil delivery system for delivering oil to an oil combustion system according to the demand of heat needed by the heating appliance to which the combustion system is installed or according to a set function of time and rate. This oil delivery system incorporates a programmable logic controller that powers a variable speed motor which drives an oil pump that electronically, versus manually, controls the oil fuel flow rate to an oil combustion system. This oil delivery system enables an oil combustion system to start at a low firing rate providing a soft start. This oil delivery system will increase the life span of a heating appliance and improve oil fuel combustion efficiency.

1 . An oil delivery system for controlling oil flow to an oil combustion system based on a function of time and rate, a sensed temperature or both time and rate and temperature, comprising of: 
 a source of oil, and    a pump means of transporting oil operatively connected in constant communication to said oil, and    a variable speed motor operatively connected to said pump, and    an electronic controller means of powering said motor, operatively connected to said motor, for accelerating and decelerating said motor by varying the electrical output to said motor based upon a function of a set time and rate, a sensed input signal or combination of both time and rate and sensed input signal,    whereby said oil is communicated to a combustion system by said pump driven by said motor powered by said electronic controller,    whereby the flow rate of said oil is controlled to said oil combustion system by the variable electrical output of said electronic controller, based upon time and rate, a sensed input or both time and rate and a sensed input of said electronic controller to said motor consequently changing the output shaft speed of said motor connected to the input means of said pump thus altering the output of said oil from said pump to said oil combustion system.    
   
   
       2 . The oil delivery system of  claim 1 , further including a temperature sensor means of communicating an electrical signal based upon a function of temperature operatively connected to said electronic controller.  
   
   
       3 . The oil delivery system of  claim 1 , further including a gear reducing coupling means of connecting said variable speed motor to said pump using a belt and pulleys or a gear reduction head or any other gear reduction means operatively connected to said motor and said pump.  
   
   
       4 . The oil delivery system of  claim 1 , further including an electrical circuit board means of converting an electrical output signal of said electronic controller to an electrical output compatible with said motor operatively connected to said electronic controller and said variable speed motor.
