IC engine fuel injection pump speed governor - has selector lever working against cam on adjustable stop

摘要

The fuel injection pump governor has an intermediate lever (18) attached to the rack (16), to a sliding intermediate bearing (23,RS) determining the amt. of rack movement, and to an adjustable position pivot bearing (19). A guide lever (12) is coupled at a point (45) adjustable along it to a setting lever (25) determining the load; to an intermediate bearing adjusted with that of the intermediate lever; and to a governor sheet (6) sliding with increasing engine speed against spring action (28). A selector lever (48) pivots on the auxiliary one in the direction of movement of the setting lever. A cam is on an adjustable stop (38), the selector lever acting against it and attached to a rocker lever (53), while a tension spring (43) between auxiliary and setting levers pulls the selector lever against the stop. The latter allows the setting lever to pivot against a full-load stop (39). The rocker lever is mounted on the governor sleeve and works with an indicator stop (55) adjustable above idling speed. ADVANTAGE - Parameter dependent adjustment.
