ABSTRACT:
A pneumatic diaphragm control member is proposed for a fuel injection device for internal combustion engines, especially for a boost-pressure dependent full-load stop, wherein the initial and end positions of a push rod provided with a control diaphragm and movable against a resetting spring can be varied, and wherein the effective pressure range is variable by means of separate adjusting means which do not affect one another. The push rod of the diaphragm control member contacts, in the unpressurized starting position, a stop screw mounted in the lid cover, and, in the pressurized end position, is in contact, by means of a counter stop attached to an extension of the push rod and adjustable in the direction of motion of the push rod, with a second end stop arranged in the pressure chamber. Thus, the bias of the resetting spring can be changed by changing the position of a bearing bushing for the push rod, which bushing serves as an abutment.
