CONTROLLING DEV-ICE FOR INTERNAL coMBUs'I'IoN ENGINES Filed .my so. 1957 Patented June 17, 1941 CONTROLLING DEVICE 'FOR INTERNAL CGIVEBUSTION ENGINES Ewald Becker, Berlin-Steglitz, Germany, assignor to Askania-Werke A. G. vormals Centralwerkstatt-Dessau und Carl Bamberg-Friedman, a
corporation of Germany Application July 30, 1937, Serial No. 156,571 In Germany August 1, 1936 9 Claims.
This invention relates to improvements in controlling devices, more particularly for fuel pumps of internal combustion engines.
Especially in aircraft engines the fuel supply depends on several factors of motor operation, on the air density within the induction pipe and on the exhaust counterpressure which naturally varies in dependence on the altitude at which the aircraft i's flying.
The object of the invention is to provide a simple and reliable controlling device by means of which the fuel quantity delivered by the pump is controlled automatically in dependence on the diiierent factors as functions of engine operation.
A further object of the invention is to facilitate the adjustment of the controlling device and to promote reliable operation.
The invention and its aims and objects will be readily understood from the following description of an embodiment in which reference is made to the drawing in which Fig. 1 is a diagrammatic plan view of the controlling device;
Fig. 2 is a sectional view of the device.
In the embodiment shown, the controlling device comprises a casing I in which is arranged a fluid pressure relay 2, e. g. a sliding valve, as well as the servo-motor 3. A chamber 5 for a capsule or bellows system 6 communicates with the induction pipe of the combustion engine (not shown) through an opening 7. 'I'he capsule system 6 comprises a number of single capsules or diaphragms 6, 6', 6". Each contains a certain volume of gas of a predetermined density. If the density of air in the chamber 5, i. e. in the induction pipe of the motor decreases, then the capsules 6, B', 6", expand, thereby displacing the slide valve 2. by means of a pin 8, extending through a wall 4 and a lever 9 linked at 9 to the valve 2. By a downward movement of the pin 8 the lever 9 is moved clockwise, resulting in a downward displacement of the valve 2. thereby allowing in a Well known manner the passage of a pressure iiuid, e. g. oil, to the left side of the servo-motor so that its piston I2 will be moved to the right. To the piston rod I3 is connected an adjusting member 32 in a manner hereinafter more fully explained, this adjusting member being adapted in a well known manner to vary the effective strokey of the fuel pump I'I, thereby varying the quantity of fuel fed to the motor.
When addusting the effective stroke of the fuel pump by means of the member 32, a restoring action is exerted at the same time on the valve 2. The piston rod I3 .is provided with a toothed rack I4 engaging a. pinion I5 fastened to a cam-disc I6, rotatably mounted in .the casing I. One end of the lever 9 rests on said disc as shown in Fig. 2 so that upon each rotation of the disc corresponding to the movement of the piston rod, this end of the lever 9 will be displaced upwardly or downwardly. In the case above mentioned in which the piston rod moves to the right, the disc will be rotated clockwise so that corresponding to the curve of the disc, the lever 9 will be swung counter-clockwise around a pivot-point represented by the pin 8. In this case the valve2 is Vpushed upwardly into its middle or neutral position by means of a spring II. Obviously. the valve will be restored by a downward movement in case of a left-hand movement of the servomotor piston I2.
From the foregoing explanation it follows that the stroke of the piston depends not only on the capsule stroke, but `also on the restoring iniiuence, i. e. on the form given to the cam-disc I6. Therefore, by the choice of the-curve it is possible to achieve a stroke of the piston I2 and the adjusting member 32 which corresponds to the fuel quantity needed by the motor for any existing air density.
The dependency of the quantity of fuel on the air density is differentfor each type of motor, each motor type having a certain characteristic with reference to the most favourable fuel consumption.
The entire controlling device may be easily adapted to the special motor characteristic by changing the form of the cam I6. For this reason it may be advisable to arrange the cam I6 in a mannery so'that it may be exchanged. Furthermore, itis possible to arrange several cams side by side so that any cam may be set into operation by an axial displacement of the entire l cam body.
In view of the fact that the form of the lcam is essential for an exact control of the fuel supply in accordance with the motor characteristic, it is desirable to have a long cam surface whichas experience has taughtmay be manufactured with greater exactness than a short one.v For this reason according to the invention the customary restoring cam directly fastened to the piston rod is replaced by a rotary cam disc having a long cam path which in spite of its length may be arranged within the smallest space.
With reference to the restoring operation as explalned above the advantage is to be noted that the distance between the point of engagement of the cam It and the lever l and its pivot aids il is materially greater than the distance between the point of engagement of the capsule system 6 and lever 9 from its pivot axis Therefore, the' point of engagement of the cam iii and lever d has a greater stroke than the point oi engagement of the capsule system i3 and lever ii, thereby increasing the exactness of the controlling operation.
f it is desired to control the fuel supply not only in accordance with the air density in the induction pipe, but also in accordance with the exhaust counter pressure, the temperature of the exhaust gases, the percentage of carbon-oxide of said gases any other factors or functions of engine operation, according to the invention, these additional controlling movements may be transmitted to the capsule system 6 in such a manner that this system is displaced as a Whole inc'iependentlyof the existing air density. For this purpose the capsule system 5 is not iixedly attached to seid casing l, but is supported by means of adjusting members adapted to be adjusted by the corresponding additional controlling factor and to displace the capsule system as a whole, thereby transmitting the additional controlling movement to the lever 9 and to the adjusting member 32 of the fuel pump in the manner above explained.
As adjusting members for the additional controlling movements, there are provided in the embodiment shown two screw rings I3 and IS, the outer ring i8 being screw threaded into the casing I, while the inner ring I8 is screw threaded into 'the outer ring. Into the inner ring I9 by means of a thread of a diiTer-ent or opposite pitch than the rlrst screw thread is screw threaded a vsupporting member supporting the capsule system by means of a thread of a dierent or opposite pitch to the 'second screw thread. Each of the screw rings may be independently rotated by means of arms itl' and i9', respectively. Furthermore, the supporting member 2o may likewise be rotated by means of an arm 2li'. Any rotation of the ring i3 or i9 or of the supporting member 2Q results in a vertical displacement of the entire capsule system d.
As indicated schematically in Fig. l, the arms it', Iii and 2li are connected in any convenient manner with the corresponding control devices El, 25T, 231i, respectively which are responsive to various functions of engine operation. The control device Zi, e. g. may be responsive to the temperature of the erhaust gases (in the exhaust conduit of the motor) The inner end of the supporting member 2li forms with the upper capsule 5 a chamber 24 which communicates with the atmosphere so that atmospheric pressure exists in this chamber and any change in said pressure influences the capsule system E. By reason of this additional chamber in front of the capsule system 6 being in communication with the atmosphere there is obtained a correction for the variation in exhaust back pressure with any change in altitude.
It is to be noted that the controlling device according to the invention permits controlling the fuel supply in accordance with a plurality of individual factors or functions of engine operation without the necessity of providing for each factor a special controlling device.
As explained above the chamber communi cates with the induction pipeV of the motor through an opening l. The capsule system li in said chamber is provided to control the servomotor in accordance with the air density in the induction pipe. As is well known, the air density is a function oi the temperature; therefore, it is important that the air in the chamber E sur rounding the capsule system 6 is caused to have the same temperature as the air in the induction pipe by permitting a small amount of air to enter the chamber 5 by any suitable means. For this purpose, means are further provided to protect the air in the chamber 5 against any heating from'outside as e. g. from the heat radiated by the motor cylinders.
In the embodiment shown the casing wall of the chamber 5 is provided with a heat-insulating layer or lining 25, e. g. a rubber layer having, if desired a good reflecting coating of, i'or example, aluminum bronze. Besides this another heatv1 insulating layer 26 is provided to prevent a transmission of heat from the wall of the c' ring i to the adjusting members I8, I 9, 2U of thu capsule system B. Likewise the Wall 4 may be of heat insulating material such as, moulding material having a fabric insertion so as m act at the same time as a shock absorber or vibration dampen.
In many cases it may be desired to vary the length of the connecting rod between the piston I2 of the servo-motor and the adjusting member 32 of the fuel pump I1. Therefore, according to the invention, a turn buckle 21 is inserted in said controlling rod, said turn buckle having in a wellknown manner a left-hand screw and a righthand screw so that upon rotation of the buckle in one direction the connecting rod is shortened and upon rotation in opposite direction the connecting rod will be lengthened. The buckle El may be rotated automatically during the controlling operation of the controlling device to vary the effective length of the connecting rod by any controlling device responsive to some additional function of engine operation which is to be taken into consideration,
In case of such an automatic control of the effective length of said controlling rod the turn buckle 21 is provided with teeth 22 in the manner of a gear, said teeth extending axially over the entire length of the buckle. (See Fig. 2.) 2! is a worm or spur gear rotatably mounted in the casing I and meshing with the teeth 28, so that, upon rotation of the Worm, the buckle 21 will also be rotated. To the axis of the worm 29 is fastened an arm 30 which may be connected in any suitable manner with an additional controlling device, schematically shown at 3l. If the piston rod I3 is displaced by the piston I2 in the manner described, the teeth 28 of the buckle 2l' slide in the worm 29 without any rotation of the buckle 21. On the other hand in spite of a longitudinal displacement, the buckle 21 may at any time be rotated by rotation of the worm 2S. The device 3| may be adjusted in accordance with the (B. t. u.) heat content o! the fuel per quantity unit, in accordance with the speed of the engine or of any other factor.
If for any reason the controlling device fails to operate, it is desirable that the pilot may be able to manually actuate the adjusting member 552 of the fuel pump I1. As long as the member 32 is rigidly connected with the piston I2 of the servo-motor, the manual operation demands great exertion of strength. For this reason it is advisable to provide means by which the connec tion between the adjusting member 32 and the piston I2 may at any time be broken.
In the embodiment shown this means comprises a yieldable fork 33 frictionally ensuing a ball Il iixed to one end of the rod connected to the piston rod Il by' means of the above mentioned The present invention is not restricted to the particular embodiment shown and described.
