Pre-start engine lubrication system

Claim 2

A pre-start engine lubrication system for engines having inlet and outlet ports to receive and discharge engine lubricating oil, said engine having internal lubrication galleys, said inlet port being in communication with said lubrication galleys, said lubrication system comprising an oil reservoir external to said engine for storing oil said reservoir having an inlet port and an outlet port, pump means in said oil reservoir for delivering pressurized oil to said reservoir outlet, and an adapter-connector adapted for engagement with said engine and including apertures mating with said engine inlet and engine outlet ports, one of said apertures being in communication with said engine inlet port and another of said apertures being in communication with said engine outlet port, means including said adapter-connector for conducting engine oil from said engine outlet port to said reservoir inlet port, and means including said adapter-connector for conducting said pressurized oil from said reservoir outlet port through said adapter-connector and through said engine inlet port to said engine lubrication galleys prior to starting said engine, thereby to provide pre-start lubrication to the interior of said engine.

Claim 3

A system according to claim 1 in which said means including said adapter-connector for conducting pressurized oil includes channeling means for channeling said pressurized oil solely through said inlet port and said engine lubrication galleys.

Claim 4

A system according to claim 1 in which said system further includes an oil filter and in which said adapter-connector includes means for mounting said filter on said adapter-connector in operational engagement therewith.

Claim 5

A system according to claim 2 in which said system further includes an oil filter and in which said adapter-connector includes means for mounting said filter on said adapter-connector in operational engagement therewith.

Claim 6

A system according to claim 2 in which said channeling means includes a check valve.

Claim 7

A system according to claim 3 in which said channeling means includes a check valve.

Claim 8

A system according to claim 4 in which said channeling means includes a check valve.

Claim 9

A system according to claim 7 in which said check valve is responsive to the pressure of said pressurized oil to assume a closed state and responsive to engine oil pressure to assume an open state.

Claim 10

A system according to claim 4 further including enabling means for preventing engine start until the pressure of said pressurized oil delivered to said engine exceeds a predetermined threshold and for enabling the starting of said engine when said pressure exceeds said threshold.

Claim 11

A system according to claim 4 further including means to terminate flow of engine oil through said means for conducting engine oil to said reservoir when the oil reaches a predetermined level in said reservoir.

Claim 12

A system according to claim 10 wherein said means for terminating comprises a float valve.

Claim 13

A system according to claim 11 wherein said means for delivering pressurized oil to said reservoir outlet port comprises a motorized gear pump within said reservoir.

Claim 14

A pre-start engine lubrication system for engines having an outlet port to discharge engine lubricating oil to an oil filter and an inlet port to receive oil from said filter, said engine having internal lubrication galleys, and said inlet port being in communication with said lubrication galleys, said lubrication system comprising an oil reservoir external of said engine for storing a quantity of engine oil, said reservoir having a separate inlet and outlet ports, means including an electrically operated motorized pump within said oil reservoir for delivering oil stored in said reservoir to said reservoir outlet port under pressure, an adapter-connector adapted for engagement with said engine and for conducting engine oil through an oil filter, said adapter including apertures mating with said engine inlet and engine outlet ports, one of said apertures being in communication with said engine inlet port and the other of said apertures being in communication with said engine outlet port, said adapter further including an exit port and an entry port and a normally closed check valve channeling means for channeling oil from said entry port to said engine inlet port, said check valve means assuming an open state in response to oil pressure from said oil filter being greater than oil pressure at said entry port, and means including said adapter-connector for conducting oil under pressure from said reservoir outlet to said entry port through said adapter-connector and through said inlet port to said engine lubrication galleys prior to starting of said engine, thereby to provide pre-start lubrication to the interior of said engine.

Claim 15

A pre-start engine lubrication system for engines having an outlet port to discharge engine lubricating oil to an oil filter and an inlet port to receive oil from said filter, said engine having internal lubrication galleys, and said inlet port being in communication with said lubrication galleys, said lubrication system comprising an oil reservoir external of said engine for storing a quantity of engine oil, said reservoir having a separate inlet and outlet ports, means including an electrically operated motorized pump within said oil reservoir for delivering oil stored in said reservoir to said reservoir outlet port under pressure, an adapter-connector adapted for engagement with said engine and for conducting engine oil through an oil filter, said adapter including apertures mating with said engine inlet and engine outlet ports, one of said apertures being in communication with said engine inlet port and the other of said apertures being in communication with said engine outlet port, said adapter further including an exit port and an entry port and a normally closed check valve channeling means for channeling oil from said entry port to said engine inlet port, said check valve means assuming an open state in response to oil pressure from said oil filter being greater than oil pressure at said entry port, and means including said adapter-connector for conducting oil under pressure from said reservoir outlet to said entry port through said adapter-connector and through said inlet port to said engine lubrication galleys prior to starting of said engine, thereby to provide pre-start lubrication to the interior of said engine.

Claim 16

A system according to claim 13 further including means interconnecting said exit port of said adapter with the inlet port of said oil reservoir and effective upon starting of said engine to replenish the oil in said reservoir.

Claim 17

A system according to claim 14 further including means to terminate said replenishing of oil when the oil reaches a predetermined level in said reservoir.

Claim 18

A system according to claim 15 wherein said means to terminate comprises a float valve.
