Abstract:
An electric boost pump oiler system is set forth to assist the engine driven oil pump of a motorcycle engine, to prevent the decrease of oil pressure at a preset value of 10 psi automatically during above normal oil operation temperatures at engine idle speeds. Additionally before engine start, the boost pump oiler will automatically deliver oil through the engine for 10 seconds to prevent internal mechanism dry starts and prime the hydraulic lifters. Additionally in the event of an engine driven oil pump failure, the boost pump oiler will automatically deliver oil pressure through the engine&#39;s internal mechanisms to prevent engine seizure. Additionally to remove oil from the oil tank, a drain hose will quick connect to the output port of the boost pump oiler delivering oil to a collection container. Additionally the oiler mounts in a saddle bag for concealment with quick connect/disconnect hoses and quick connect/disconnect electrical fittings for saddle bag removal.

Description:
FIELD OF INVENTION 
       [0001]    The present invention relates generally to a motorcycle and a oil boost pump apparatus that is electrically power driven by a motorcycle&#39;s electrical system for delivering additional oil pressure and volume to the motorcycle&#39;s engine. 
       BACK GROUND OF INVENTION 
       [0002]    A boost pump apparatus mounted in a motorcycle saddle bag that is fluid communicated through hoses from a motorcycle oil tank output to a low pressure boost pump input delivered by a gear head oil pump output communicated to the input pressure galley of a motorcycle engine. In the art of discovery of a V-Twin air cooled motorcycle engine that is design with the use of hydraulic valve lifters, must have adequate oil pressure and volume to produce the manufactures designed of hydraulic lifter performance such as “Andrew&#39;s Cam manufacture” specifications of 10 psi and above. 
         [0003]    Oil pump design such as a Harley-Davidson motorcycle V-Twin air cooled engine driven gerotor stock oil pump is factory set to operate fluid pressure at, a range of 5 psi at its lowest to 38 psi at its highest under normal operating temperatures considered by the factory&#39;s engine service manual. 
         [0004]    As the oil temperature begins to rise above normal operating temperatures due to inadequate air flow across the engine cylinders, above normal temperatures, oil viscosity begins to decrease the performance of the engine driven gerotor oil pump&#39;s psi and volume. At engine idle speeds, oil pressure and volume falls below 10 psi producing poor hydraulic lifter performance for correct valve train push rod clearance operation. These results of incorrect valve lash clearance will cause internal mechanism damage to, the valve train push rod operation. 
       SUMMARY OF INVENTION 
       [0005]    The object of the present invention, is to assist the motorcycle&#39;s engine driven oil pump to maintain a constant oil pressure and volume at 10 psi for normal hydraulic lifter performance, design by the hydraulic lifter manufacture&#39;s specification. 
         [0006]    In a further object of the present invention, is to perform an oil priming fluid flow pre engine start cycle that primes the hydraulic lifters and protects the internal mechanisms from metal to metal friction that could cause damage to the engine during starting. 
         [0007]    In even a further object of the present invention, is to provide adequate fluid pressure and volume to the engine&#39;s mechanisms in an event of a motorcycle engine driven oil pump failure that could lead to a catastrophe internal mechanism failure. 
         [0008]    In yet even a further object of the present invention, is to perform a quick drain oil tank fluid cycle for removal of the motorcycle&#39;s engine oil from the oil tank so as to replace it with a new oil product. 
       DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0009]    Accordingly, there is set forth an auxiliary electric low pressure oil booster pump comprising of an oil pump system that is mounted on a motorcycle in a enclosed box to install inside the saddle bag for storage and operation with a connect/disconnect fluid coupled communication and a electrical quick connect/disconnect coupled communication so as remove the saddle bag for access required to service the motorcycle. 
         [0010]    Within the cast aluminum square box with an access lid, includes an electrical 12 volt dc small motor, close coupled to a gear head pump in communication from the engine&#39;s oil tank output to a communication input of a magnetic filter screen output to a check valve input to the oil pump input to the said pump output to communicate input to a check valve output to the input of the engine&#39;s oil pressure galley. 
         [0011]    Electrically communicated output from the motorcycle&#39;s electrical ignition switch system, a quick connect/disconnect coupled communication to an electronic control relay unit input, communicates output to the said oil pump motor input to operate automatic functions for a time delay “on” 10 second boost pump fluid priming output cycle to the quick connect/disconnect coupled communication input of the engine&#39;s oil pressure galley before engine start; then disconnects electrical output communication from the said relay to the input of the said pump motor to cease oil pressure boost pump fluid output to the input of the engine&#39;s oil pressure galley. 
         [0012]    After engine start, the output of the motorcycle&#39;s electrical charging system reaches 13.5 volts; a communication input to trigger the said relay output for providing electrical voltage to communicate input to a preset 10 psi normally closed oil pressure switch output, providing electrical voltage communication to the input of the said pump motor as required. 
         [0013]    The value oil pressure fluid below 10 psi input of said oil pressure switch will be communicated electrically to the input of the said pump motor to operate the said oil boost pump continuously to boost additional oil pressure and volume fluid to the input of the engine&#39;s oil pressure galley that will provide adequate oil to the hydraulic lifters and internal mechanisms. 
         [0014]    When the value oil pressure fluid above 10 psi output of the engine driven oil pump, communicates fluid input of the said psi oil switch, the said switch will communicate electrically from the said electronic control relay to the said oil switch input to the said oil switch output to the said pump motor input to cease operation of the said oil boost pump fluid output to the oil pressure fluid input of the engine&#39;s oil pressure galley. 
         [0015]    After engine shutdown; the motorcycle&#39;s electrical charging system voltage value of 14.5 decreases to 12.0 voltages. As the voltage decreases through 13.5 volts, an electrical communication to the trigger of the said relay input communicates the said relay to disconnect input voltage communication from the output communication of the motorcycle&#39;s 12 volt electrical system, so as if left energized below 13.5 volts, will prevent operation of said pump motor and said oil boost pump from continuously providing fluid boost pump pressure communication to the input of the engine&#39;s oil pressure galley during engine shutdown. 
         [0016]    Access outside the said box is a 10 amp fuse holder with cap to replace the fuse that protects the electrical current to the said relay and said boost pump motor in the event of a current load above 10 amps. 
         [0017]    Also a cover protected electrical on-off toggle switch to energize communication input from the motorcycle&#39;s electrical ignition switch output, communicates the said pump motor input, to drive the said oil boost pump input, to communicate engine oil tank output fluid flow to the said oil boost pump input to said pump output to communicate fluid flow to remove engine oil through a quick connect/disconnect coupled output hose in place of the engine&#39;s oil pressure galley input hose to collect the oil outside of the engine&#39;s oil tank for disposal.
