Specification of Letters Patent.
Patented Apr. 30, 1912.
Application filed January '7, 1911. Serial -No. 801,423.
To all whom it may concern:
Be it known that we, ERNST Monwns, a subject of the King of Prussia, and resident of Marienfelde, near Berlin, Germany, managing director, and ALFRED VIsCIIER, a subject of the King of Wurttemberg, and resident of 42 LudWigst-rasse, Cannstatt, Ger man Empire, engineer, have invented new and useful Improvements .in Internal-Combustion Engines, of which the followingv is a specification.
This invention relates to internal combustion engines, in which a so-called accelerator-lever or pedal is provided by which the carbureter is controlled, so that more or less fuel or air may be admitted to the working cylinders and the working power of the engine accordingly varied. It is then desirable to supply more or less lubricating oil to the working parts of the engine according to the power developed by the'engine, and thisin vention has for its object to provide an improved arrangement for automatically regulating the supply of lubricating oil.
It is already known to control the supply of lubricant according to the speed of the engine by connecting the lubricating oil regulator with the spark timing device. Such arrangements fulfil their purpose to a certain extent, inasmuch as the friction of the parts to be lubricated increases with increased speed but such arrangements do not take into account the fact that the friction set up is not only dependent on the speed of theengine but is also affected by the varying pressure in the engine due to the varying load on the engine, that is to say, the friction is dependent on the turning moment of the engine. The load and turning moment of the engine are however-almost directly proportional to the charge supplied to the engine which is determined by regulating the throttle-valve of the carburetcr.
The object of the present invention is therefore to enable the supply of lubricant to be so regulated that, on' an increased supply of combustible to the engine cylinder, the supply of lubricant may be correspondingly increased, and vice-versa, as a greater quantity of lubricating oil is required on increasing the engine power owing to the greater friction resulting therefrom.
According to this invention the accelerator-pedal is connected with an. arrangement for regulating the supply of oil as well as to the carburetor, so that the supply of oil to the parts to be lubricated is automatically varied simultaneously with the control of the carbureter and consequent variation in,
, illustrated by way of example.
Figure 1 is a side-view showing one method of carrying out the invention, in which the oil regulating valve is interposed between a branch oil circuit and a main oil circuitleading to the parts to be lubricated. Fig. 2 is a similar view to Fig. 1 but in which the oil regulating valve is arranged in'the branch oil circuit and in proximity to a sight-glass in the circuit.
Referringto Fig. l of the drawings, the
accelerator-lever or pedal a is in the form.
of a foot-lever and operates a three-armed lever 0 through the rod Z), the lever 0 being connected by means of its arm d with the regulating device of the carburetor f and by means of its arm 9 with a three-Way cock is, which is arranged in a pipe 1' leading from the oil-pump h to the parts to belubricated. A pipe Z passes from the three-way cook 71: and is connected through a sight-glass m with a return pipe n leading to the oil-container 0 from which oil is drawn by means of the oil-pump h. \Vhen the three-way cock is in such a position as to cutoff or throttle the supply of oil to the parts to be lubricated, then the excess of-oil, which cannot pass through the pipe 2', passes through the pipe Z, sight-glass m and pipe n and is returned to the oil-container 0. Any suitable means may of course be employed for regulating the oil-supp y in lieu of the threeway cock 7c.
According to the arrangement shown at Fig. 2, the lever which is operated by the accelerator pedal a by means of the rod 1) comprises only two arms 0 and d; the arm 0 being connected to the rod 6 and the arm (l to the regulating device of the carbureter The pipe 2', l ading to the parts to be lubricated, is in this case connected to the pipe I which conununicates with the return pipe 12- leading to the oil-container 0 through an intermediate throttling device grand sight-glass m. The accelerator pedal a is connected by means of an arm at an will! angle thereto and by a draw-bar Q with a lever r, by which the throttling device 39 is controlled When the throttling device is so controlled by means of the accelerator pedal (4 that full communication is estal lished between the pipes Z and n, the greater part of the oil-supply from the oil-pump it will then return through these pipes to the oil-container 0. If however the throttling device is controlled in such a manner that it more or less cuts ofl communication between the pipes Z and a only a smaller part of the oil will return to the oil -container 0 through these pipes, while the greater part of the oil from the pump 72 will be supplied to the parts to be lubricated by the pipe In this latter construction the arrangement of the throttling device in the return pipe has the advantage that-the choking of the' pipesleading to the parts to be lubricated and which by the insertion therein of a throttling device is liable to take place, is obviated; By the arrangement of the throt-, tling device in the return pipe sutticient oil is therefore constantly supplied to the parts to be lubricated, according to requirements, no matter whether the throttling device is working properly or only allows a smaller quantity of oil to pass owing to it being possibly choked. 7
