Abstract
Abstract A lubricating system for automotive components includes an oil reservoir to supply an initial charge of lubricating oil upon cold starting of the engine, with provision to maintain the reservoir in a full attitude after the engine lubricating oil has warmed and is freely circulating, thereby preserving a charge of oil available for the next cold starting of the engine.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
136 words
Apparatus for the lubrication of a turbo charger unit of the type having an impeller rotatably supported on bushings, said turbo charger unit mounted to an internal combustion engine, said engine of the type being lubricated by motor oil and having a pump for the circulation thereof throughout said engine, said apparatus comprising: an outer, liquid-tight vessel; an inner vessel smaller than said outer vessel and positioned within said outer vessel; means to provide a portion of the flow of said lubricating oil to said inner vessel; means to direct said lubricating oil from said inner vessel to said outer vessel during operation of said engine; means to selectively drain oil retained in said inner vessel to said outer vessel; and means to conduct a flow of oil from said outer vesselto said turbo charger unit.
Claim 2
Dependent Claim
136 words
Apparatus for the lubrication of a turbo charger unit of the type having an impeller rotatably supported on bushings, said turbo charger unit mounted to an internal combustion engine, said engine of the type being lubricated by motor oil and having a pump for the circulation thereof throughout said engine, said apparatus comprising: an outer, liquid-tight vessel; an inner vessel smaller than said outer vessel and positioned within said outer vessel; means to provide a portion of the flow of said lubricating oil to said inner vessel; means to direct said lubricating oil from said inner vessel to said outer vessel during operation of said engine; means to selectively drain oil retained in said inner vessel to said outer vessel; and means to conduct a flow of oil from said outer vesselto said turbo charger unit.
Claim 3
Dependent Claim
46 words
The apparatus as recited in claim 1 wherein said outer vessel has a bottom, said oil conducting means including an outlet formed in said bottom, said oil conducting means further including conduit means to carry said lubricating oil from said outlet to said turbo charger unit.
Claim 4
Dependent Claim
22 words
The apparatus as recited in claim 2 wherein said outer vessel bottom is curved to direct said lubricating oil to said outlet.
Claim 5
Dependent Claim
39 words
The apparatus as recited in claim 1 wherein said directing means includes a series of ports formed through said inner vessel communicating to said outer vessel, whereby lubricating oil reaching said ports will flow therethrough to said outer vessel.
Claim 6
Dependent Claim
27 words
The apparatus as recited in claim 1 wherein said drain means includes an outlet, and solenoid actuated valve means positioned to selectively open or close said outlet.
Claim 7
Dependent Claim
22 words
The apparatus as recited in claim 5 wherein said solenoid-actuated valve means operates responsive to a selected operating characteristic of said engine.
Claim 8
Dependent Claim
18 words
The apparatus as recited in claim 6 wherein said operating characteristic is the operating temperature of said engine.
Claim 9
Dependent Claim
17 words
The apparatus as recited in claim 6 wherein said characteristic is the temperature of said lubricating oil.
Claim 10
Dependent Claim
18 words
The apparatus as recited in claim 6 wherein said characteristic is the operating pressure of said lubricating oil.
Claim 11
Dependent Claim
19 words
The apparatus as recited in claim 1 wherein said outer vessel has a selectively removable lid fitted liquid-tightly thereto.
Claim 12
Dependent Claim
103 words
Method for providing lubrication to a turbo charger unit mounted to an engine, said engine of the type having an oil pump to circulate oil therethrough, said method comprising the steps of: a. pumping said oil to a reservoir during the operation of said engine; b. overflowing said reservoir during the operation of said engine; c. directing said overflowed oil to said turbo charger unit during operation of said engine; d. retaining a quantity of said oil in said reservoir when said engine is turned off; and e. draining said retained oil to said turbo charger unit upon subsequent restarting of said engine.
Claim 13
Dependent Claim
103 words
Method for providing lubrication to a turbo charger unit mounted to an engine, said engine of the type having an oil pump to circulate oil therethrough, said method comprising the steps of: a. pumping said oil to a reservoir during the operation of said engine; b. overflowing said reservoir during the operation of said engine; c. directing said overflowed oil to said turbo charger unit during operation of said engine; d. retaining a quantity of said oil in said reservoir when said engine is turned off; and e. draining said retained oil to said turbo charger unit upon subsequent restarting of said engine.
Claim 14
Dependent Claim
23 words
Method of claim 11 including the step of: f. continuing the draining of said reservoir until said engine reaches a pre-selected operating temperature.
Claim 15
Dependent Claim
27 words
The method of claim 11 including the step of: f. continuing the draining of said reservoir until the operating temperature of said oil reaches a pre-selected temperature.
Claim 16
Dependent Claim
27 words
The method of claim 11 further including the step of f. continuing the draining of said reservoir until the pressure of said oil reaches a pre-selected value.
