ABSTRACT:
A device for regulating a diesel motor driven feed pump which includes an injection pump associated with the diesel motor to control its operating speed, comprises a load, a variable pressure resistance connected by a feed line in series in series to the feed pump and a sump for the feed pump connected to the pressure resistance. In addition a control circuit is connected to the feed line and it includes a pressure scale portion and a limiting device portion each of which includes a respective pressure scale cylinder and limiting device cylinder portion for their respective coaxially arranged pressure scale piston and limiting piston slidable therein. A differential manometer is connected between the pressure scale portion and the limiting portion and it is admitted with the flow medium of respective differential pressures of the associated cylinders of these portions. A regulating drive is connected to the flow medium and it is admitted by the respective differential pressure between the two cylinders and it is connected to the injection pump to vary the operation of the pump.
