Abstract
Abstract A lubricating arrangement for an I.C. engine in which at least one lubricating pump for engine lubrication is activated by a battery-fed electric motor, independent of the I.C. engine, which supplies a preset oil quantity which is unrelated to the rpms of the I.C. engine. As this lubricating pump is driven by a battery-fed electric motor which runs up within a fraction of a second, the I.C. engine is instantly under pressure with a full quantity of lubricating oil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
Motor vehicle with an internal combustion engine, characterized in that for lubricating the internal combustion engine, at least one lubricating pump is powered by a battery-fed electric motor, independent of the internal combustion engine, which supplies a preset oil quantity which is unrelated to the revolutions per minute of the internal combustion engine, said electric motor powering the lubricating pump being coupled with a device for activating or starting the internal combustion engine in such a way that upon turning on a selector switch, an ignition, or a starter, respectively, the electric motor powering the lubricating pump is simultaneously switched on.
Claim 2
Dependent Claim
101 words
Motor vehicle with an internal combustion engine, characterized in that for lubricating the internal combustion engine, at least one lubricating pump is powered by a battery-fed electric motor, independent of the internal combustion engine, which supplies a preset oil quantity which is unrelated to the revolutions per minute of the internal combustion engine, said electric motor powering the lubricating pump being coupled with a device for activating or starting the internal combustion engine in such a way that upon turning on a selector switch, an ignition, or a starter, respectively, the electric motor powering the lubricating pump is simultaneously switched on.
Claim 3
Dependent Claim
72 words
Motor vehicle according to claim 1 characterized by an interrelationship of the electric motor powering the lubricating pump with the internal combustion engine in such a way that upon the internal combustion engine surpassing a minimum revolutions per minute, the electric motor powering the lubricating pump is turned off, and the supply of lubricating oil to the internal combustion engine is provided by a lubricating pump coupled to the internal combustion engine.
Claim 4
Dependent Claim
92 words
Motor vehicle according to claim 1 characterized in that additionally to a lubricating pump supplying an increasing oil quantity as the rpm of the internal combustion engine is increased, there is a lubricating pump powered by an electric motor, and in that both lubricating pumps feed the lubricating oil supply lines to the lubricating points, and further, that in at least one, but preferably both hydraulic lines branching off from the mentioned lubricating pumps, there is a built-in check valve, preventing a flow-back of the lubricating oil to the associated lubricating pump.
Claim 5
Dependent Claim
29 words
Motor vehicle according to claim 1, characterized in that upon surpassing a predetermined rpm of the internal combustion engine, the rpm of the lubricating pump is being increased proportionately.
Claim 6
Dependent Claim
18 words
Motor vehicle according to claim 1, characterized in that the electric motor is designated as a shunt motor.
Claim 7
Dependent Claim
22 words
Motor vehicle according to claim 1, characterized in that the electric motor has a field generated by at least one permanent magnet.
Claim 8
Dependent Claim
36 words
Motor vehicle according to claim 1, characterized in that the internal combustion engine has an ignition arrangement with a preignition switch and in that fuel, is injected immediately after a first compression in a pulsed manner.
