ABSTRACT:
An over ride oil pump for use with reciprocating or rotary engines which provides auxiliary oil pumping under three circumstances by use of an electrically operated oil pump, digital circuitry and sensors. As a car is started the standard mechanical oil pump cannot provide adequate lubrication since the mechanical pump can only pump at a rate proportional to engine speed. The over ride pump begins immediately, upon initiation of engine start up. Under conditions of high RPM operation extra lubrication is required. The over ride oil pump senses increased vacuum levels and provides additional oil delivery. Oil pressure drops rapidly if there is a failure in the mechanical pump drive mechanism or the pump itself. The over ride oil pump senses this deficiency and provided the necessary oil delivery.
