Abstract: THE FUEL RACK OF A FUEL INJECTION PUMP IS REGULATED AS A FUNCTION OF THE ENGINE R.P.M., THE POSITION OF THE ARBITARILY OPERATED BUTTERFLY VALVE AND OTHER OPERATIONAL VARIABLES. FOR THIS PURPOSE AN ELECTRIC SIGNAL REPRESENTING A DESIRED VALUE IS DERIVED FROM THE ANGULAR AND AXIAL POSITIONS OF A THREE-DIMENSIONAL CAM (WHICH ASSUMES ITS POSITION IN RESPONSE TO AN ELECTRIC SIGNAL CHARACTERIZING THE ACTUAL ENGINE R.P.M. AND IN RESPONSE TO A MECHANICAL SIGNAL CHARACTERIZING THE ACTUAL POSITION OF THE BUTTERFLY VALVE) AND IS COMPARED WITH AN ELECTRIC SIGNAL REPRESENTING AN ACTUAL VALUE DERIVED FROM THE ACTUAL POSITION OF THE FUEL RACK. THE ELECTRIC SIGNAL RESULTING FROM SAID COMPARISON IS APPLIED TO A CONTROL MEMBER WHICH IS DISPLACED ACCORDINGLY AND WHICH, BY VIRTUE OF ITS CONNECTION WITH THE FUEL RACK, CAUSES A CORRESPONDING MOVEMENT OF THE LATTER. ELECTRIC CORRECTING SIGNALS REPRESENTING PHYSICAL
MAGNITUDES, SUCH AS ENGINE TEMPERATURE AND ATMOSPHERIC PRESSURE, VARY THE DESIRED AND/OR ACTUAL VALUE SIGNALS PRIOR TO THEIR COMPARISON.-

Abstract: A suspension system for supporting the body of a motor car includes cylinder and piston means connecting the body with the wheel shafts and forming first and second chambers connected with first and second sources of pressure fluid. A regulating valve varies and adjusts the flow cross section of the first and second conduits and thereby the flow of the pressure fluid into the first and second chambers until no resonance oscillations of the body take place.

Abstract: An electromagnet has a pot-shaped enclosure having a cylindrical portion and consisting of magnetizable material, and an elongated guide means which consists of non-magnetizable material and extends substantially centrally of the pot-shaped enclosure. A winding is mounted in the enclosure. An armature is slidably mounted for movement lengthwise on the guide means in response to changes in condition of energization of the winding. The enclosure has a pole piece which defines an internal surface and the armature has an external surface defining, with said internal surface, a clearance whose width remains substantially unchanged while the armature moves with reference to the guide means. The enclosure and armature have conical pole faces which define a conical gap which varies in response to movement of the armature with reference to the guide means.

Abstract: In an internal combustion engine having a throttle in the suction duct a disc is mounted in the duct airstream on the end of a pivotable arm for controlling the fuel valve in proportion to the rate of air intake. A section of the duct between the throttle and the disc is formed by an elastic hose. The disc is mounted in an enlarged section housing the air filter and is of appreciably larger diameter than the throttle.

Abstract: In a fuel injection apparatus the air-fuel ratio is controlled by an air sensor as a function of the air quantities passing through the suction tube. Said ratio is varied by altering a liquid pressure which serves as a return force for the air sensor. The liquid pressure is varied by a valve loaded in the closing direction by a spring, the bias of which is affected, among others, during the warm-up run of the engine, by the pressure that prevails in the suction tube immediately downstream of an arbitrarily operable butterfly valve.

Abstract: In a fuel injection apparatus there is provided an air sensor which, as a function of the intake air quantities flowing through the suction tube causes movement of a fuel metering or control plunger. The return force exerted on the air sensor and opposing the force of the air flow is supplied by fuel pressure that is variable by a valve which is set by the interaction of the following forces: the difference between the air pressure upstream and downstream of the air sensor, the fuel tank counterpressure and a spring, the force of which is changeable as a function of engine variables.

Abstract: In a fuel injection apparatus - in which the air-fuel ratio is maintained constant by an air sensor displaceable in the suction tube by the intake air drawn into the internal combustion engine with which the fuel injection apparatus is associated - in order to prevent undesired shifts in the metered fuel quantities in the low rpm range, the pressurized liquid used as a return force for the air sensor passes through a throttle assembly which throttles the liquid flow to an extent dependent upon the direction of flow therethrough.

Abstract: THE POSITION OF A POSITIONING MEMBER WHICH CONTROLS THE AMOUNT OF FUEL TO BE INJECTED INTO AN INTERNAL COMBUSTION ENGINE IS DETERMINED BY DRIVING A SIGNAL REPRESENTATIVE OF ENGINE SPEED, MODIFYING THE SIGNAL TO OBTAIN AN OUTPUT REFLECTING ENGINE CHARACTERISTICS, AND THEN CONTROLLING WITH THE MODIFIED SIGNAL THE POSITION OF A CAM, PREFERABLY A THREE-DIMENSIONAL CAM, THE POSITION OF THE CAM BEING ADDITIONALLY CONTROLLED BY THE POSITION OF THE ACCELERATOR FOR THE ENGINE. A SIGNAL IS DERIVED FROM A CAM FOLLOWER, AND THIS SIGNAL IS ADDITIONALLY AFFECTED BY A CORRECTION UNIT CORRECTING FOR CHANGES IN AMBIENT AIR PRESSURE, TEMPERATURE OF THE ENGINE, OR AMBIENT CONDITIONS, OR THE LIKE, SO THAT THE FINAL OUTPUT CONTROLLING THE SETTING OF THE POSITIONED MEMBER WHICH DETERMINES THE AMOUNT OF FUEL INJECTED WILL BE REPRESENTATIVE OF ENGINE CHARACTERISTICS, THE ACCELERATOR POSITION, AND AMBIENT CONDITIONS AS SENSED BY THE CORRECTION UNIT.
