Abstract

ENGINE PRE-OILER
Abstract A pressurized vessel disclosed as an accumulator is in valve controlled communication with an oil gallery or passageway for pressuring same prior to machinery motion.
A solenoid actuated valve is energized to communicate the accumulator with the oil gallery. A flow control valve, between the accumulator and the oil gallery, automatically opens to release accumulator pressure and conversly permits recharging of the accumulator with pressurized oil during machinery operation.

Description

- ` :

~1~6~ZOZ

Specification The present invention relates generally to a pre-oiling system for machinery bearings and parts *or lubri-cating same prior to m~tion o~ the machinery.
Existing internal combustion engines, ~or example, rely on an oil pump driven in an accessory manner by the engine.
A9 normal oil pressure does not occur until moments after engine starting is initiated, lubrication during cranking and start up is inadequate. Accordingly, a rela~ively high amount of wear occurs during cranking and the first moments of engine operation by raason o~ less ~han normal lubrica tion for a period of seconds or until the oil gallery and oil passageways are suitably pressurized. The advent of multi-viscosity oils has alleviated the problem to some degree in that such oil flows more rapidly than single vis- ~-cosity oil however fast idle speeds, during intial start up of the engine, are common to modern automobile engines and ~n result in, at least momentarily, inadequate engine lubrication~
To the extent the prior art is known, certain prior patents have been concerned with this problem but have en~
deavored to solve the problem by the aspiration of oil or oil vapor into the fuel intake system for lubrication of upper piston, cylinders and valve components with no pro-vision made for lubricating other moving engine components.
Similarly, other types o~ machinery are subject to inade-quate lubrication prior to noxmal operation of the associ-ated lubrication ~ystem.
The present pre-oiling system embodles a pressuriæed oil vessel in controlled communication wlth an oil gallery with recharging of the vessel occurring sub~e~uently during .', ~ .

machine operation.
The oil vessel is shown as an accumulator delivering lub-ricant past a selectively operated valve, actuated during an engine starting sequence to pressurize an oil gallery and passageways prior to machinery motion. Additional valve means unseats to discharge the oil, The last mentioned valve means also subsequently permits a metered, reverse flow for gradual refilling of the accumulator during lubrication system opera-tion. The pre-oiling system may be provided as an accessory to existing engines or other machinery with an oil supply line being in communication with a filter by-pass housing.
According to the present pre-oiler system invention there is provided an oil vessel containing lubricant under pressure, said vessel lncluding a ba~e~ means selectively communicating the oil vessel interior with a lubrication passageway of the machinery, said means remotely actuated upon closure of an electrical circuit preparatory to starting of the machinery, and a valve assembly regulating lubricant flow between said vessel and said selectively communicating means and including a spring biased movable valve body having a first position whereat a restricked return flow of lubricant may enter said vessel during normal operation of the machinery lubrication system to gradually charge said vessel while adequate machin-ery lubrication system pressure is maintained, said valve body having a ~econd position permitting an oppositely directed out-ward flow of lubricant from said vessel for machinery lubrica-tion at a greater rate than the first position flow rate of said valve body, said movable valve body having rnultiple porks there-in some of which are closecl in said first position while other . . .

of said ports at all times other of said ports remain open.

provision of a pre-oiling system which may utilize highly reliable components of proven high reliability; and the provision of a pre-oiler including an accumulator to assure positive discharge of the oil therein.
In the accompanying drawing:
Figure 1 is a view of the pre-oiler in place on an engine block;
Figure 2 is an enlarged fragmentary view with the accumulator with fragments broken away to show valve 10 structure; and -Figure 3 is a diagrammatic of the present pre-oiler system in conjunction with engine ignition circuitry.
With continuing reference to the accompanying drawing wherein applied reference numerals indicate parts similarly identified in the following specification, the reference numeral 1 indicates an engine block fitted with an oil filter
2 supported within a by-pass housing 3 all n the more or le~s conventlonal manner~ Said housing defines an internal passageway 3A for the return of filtered oil to an engine oil gallery from whence passageways lead to various engine components, While the following described pre-oiler system is shown in association with one type of oil by-pass housing, it is to be understood that the present pre-oiler system may be adapted to suit various engines with or without similar by-pass housings, For example, the connection point between the pre-oiler and block may be at the oil pressure sensing unit location, The present pre-oiler system includes an oil vessel in the form of an accumulator having a housing 4 within which is housed a pressurized bladder 5 of a non-constant volume ~06~ii;2~Z

with remaining accumulator area being occupied by a quantity of pressurized lubricant. As best viewed in Figure 2, a retainer ring 7 secures the accumulator housing to an accum-ulator base 6.by means of fasteners 8. A seal such as an O-ring at lO extends about a grooved upright wall 9 of accumulator base 6 for sealing contact with an internal surface of housing 4.
Valve m~ans includes a flow control valve assembly, indicated generally at 11, and desir~bly located within accu~ulator hase 6 for reasons o~ compactness, Said valve assembly includes a movable valve body 12 disposed within a bore 13. A hPlical spring 14 urges valve body 12 to the seated Figure 2 position, termed a first position, during engine operation as later more fully described. Valve ports -~
at 12A are associated with the outflow of lubricant from the accumulator when said valve body is in an unseated or second po~ition while a port at 12B permits an opposite return, metered flow into the accumulator, A valve asse~bly is indicated at 16 which is in com- .
munication with accumulator base 6 via a nipple 15, Said valve assembly regulates the communication of accumulator 4 with t~e engine oil gallery (or other lubricant passageway), the valve being open during engine operation. ~ second nipple at 17 interconnects solenoid valve 16 with bore 3A in ~ ~.
the by-pass housing of the engine block.
Basic components o~ an ignition circuit are shown in Figure 3 including a power source 20 grounded at 21, a multi-position ignition switch 22 having represen-tative contacts 23 and 24 which energize in sequence a primary ignition lead 25 to an ignition coi]. and a second lead at 26 to a starter ~66Z~'~

motor. An oil pressure warning light 27 is in a conventional circuit with said source and grounded through a pressure responsive switch 28 with contacts 29.
In operation, manipulation 4~ ignition switch 22 from its off position to the "on" position shown in Figure 3 results in solenoid valve 16 being actuated to the open position shown. With solenoid valve 16 open, accumulator oil pressure unseats valve body 12 moving same to said second po~ition whereby oil flows past ~low control valve 11 ~via ports 12A therein) ~o the engine oil gallery pressurizing same. Pressure responsive switch 28 opens upon such pres-surization to interrupt the warning light circuit extinguish-ing warning light 27 which indicates to the operator the pre-oiler system has functioned to pressurize the engine oil gallery (or other oil passageway) prior to motion of the parts requiring lubrication. ~-Upon engine starting with consequent operation of the oil pump, the oil gallery is pressurized in the normal manner, at which time, a metared reverse lubricant flow will take place pa~t open control valve 16, through port 12B of seated valve body 12y into accumulator 4 resulting in same being repressurized for ~ubsequent starts. The orifice 12B in valve member 12 restricts the return flow of lubricant to the extent that engine oil pressure i9 not reduced below a safe operating pressure~
While I have shown but one embodiment of the invention, it will be apparent to thoss skilled in the art that the invention may be embodied still otherwise or use with a wide array of machinery requiring lubrication without depart- ~ ;
ing from the spirit and scope of the invention.
