Abstract
A device for regulating the delivery of a fuel injection pump of an internal combustion engine comprises a centrifugal governor coupled to a regulating member of the pump by a transmission lever so that the delivery of the pump is regulated in dependence upon engine speed. The transmission lever is pivotally connected at its ends to a control member of the governor and to the regulating member respectively, the lever being freely rotatably mounted intermediate its ends on a spindle eccentrically mounted on a pivot rotatably supported by a casing of the device. Actuating means responsive to a controlling fluid pressure is provided for rotating the pivot in order to adjust the regulating member in dependence upon the controlling fluid pressure. The actuating means comprises a differential piston received in a cylinder to define first and second permanently interconnected chambers, the first chamber of smaller cross-section being supplied with working fluid and the second chamber of greater cross-section communicating with a low pressure region via a variable throttle section defined between the differential piston and a pilot valve whose position is adjusted by a deformable unit sensitive to the controlling fluid pressure.
