  • Patent number: 4204510
    Abstract: An rpm governor for diesel engines, with which an increased starting quantity of fuel, controlled by the rpm, is released automatically when the engine is started, but which is only released during a start when the engine is cold, and which is limited to the operational maximum when the engine is warm. The governor includes a starting device with a control lever which can be moved by the regulating member of the governor, which lever is connected to a stop which either limits the quantity to the operational maximum of releases the increased starting quantity, and to a thermostat, which causes the stop to be held in its position limiting the quantity to the operational maximum despite the control lever being activated by the regulating member.

  • Patent number: 4170976
    Abstract: A control device for diesel-injection internal combustion engines, whose hydraulically activated adjusting member moves the regulating rod of the fuel injection pump in the "stop" direction when the discharge of the hydraulic medium is blocked by a magnetic valve, and simultaneously serves as an arbitrarily engageable full-load or delivery rate reducing stop for the regulating rod. The control device includes a first electromagnet, which activates the valve member of the magnetic valve, and a second electromagnet, whose control member limits the adjusting movement of the adjusting member, which can be controlled by the valve member of the first electromagnet, to a position that serves as the full-load or lower rate stop for the regulating rod of the injection pump, when the second electromagnet is engaged. This limitation takes place mechanically or by opening a return line, which determines the position of an adjusting piston that is connected with the adjusting member.

  • Patent number: 4164925
    Abstract: A centrifugal rpm governor for fuel injected motor vehicles, in which the control stroke, which is detected by a lever controlled follower on an adapting surface, is enlarged for a more precise control of the adaptation. A translated shift lever is used as the control lever, which is coupled with the governor adjusting member and the lever carrying the follower. To improve the quality of the governor, the shift lever engages an adapting lever, which carries the follower and which is arranged nearly parallel to the intermediate lever. By means of an adjusting member, which is provided with an adapting control and retraction spring, and which is separated in the governor and adapting sleeve, the use of the governor as an idling as well as a maximum rpm governor is made possible.

  • Patent number: 4143634
    Abstract: An rpm governor for fuel injection engines whose function is to raise the idle rpm for a predetermined time period while the engine is cold in order to guarantee a clean idle running cycle of the engine. The rpm governor includes a compensating device having a thermostat which is designed to engage an idling spring and whose duration of engagement is determined by a heating device located on the thermostat. When the engine is cold, the tension in the spring is raised by the compensating device, thus effecting a higher rpm level, which rpm level is later reduced to normal idle when the governor has reached an operational temperature upon the passage of a predetermined period after cold starting.

  • Patent number: 4132206
    Abstract: A centrifugal force speed governor for fuel injected internal combustion engines having at least a negative adjustment capability. In such a centrifugal force speed governor the following structural components are included: speed responsive structure; at least one adaptation spring; an adjustment member; an intermediate lever; a yield support; a control element; a stop; an energy storing structure; and a setting lever having a pin mounted thereto. The adjustment member is coupled to the speed responsive structure, the adaptation spring, the control element and through the control element to the yield support, while the setting lever engages, with its pin, the intermediate lever, the control element and the energy storing structure. When the adjustment member is displaced by the speed responsive structure and under the regulation of the adaptation spring, a displacement of the intermediate lever via the control element and the setting lever pin occurs.

  • Patent number: 4085724
    Abstract: The invention relates to a fuel regulator for internal combustion engines provided with a fuel injection system and with an adjusting member that operates preferably in dependence on the rpm, which moves the control rod of the fuel metering system via an intermediate lever. The intermediate lever is mounted on the pin of a bell-crank and effects an independent movement of the fuel control rod. The controller further includes a correcting device through which the position of the pin and thus the position of the fuel control rod can be changed independently and as a function of at least one operational variable, preferably the atmospheric pressure.
