Abstract
In all-speed governors controlled by centrifugal force and controlling the full-load fuel delivery quantity of the respective fuel injection pump as a function of boost pressure, the starting fuel delivery is to be reduced at higher operating temperatures of the internal combustion engine to prevent smoke bursts during warm starting. For this purpose, the speed governor has an added support provided in addition to a base support and supported of the later swivelably between two adjusting stops. In addition to a full-load stop arranged on the base support, the added support has an added stop which can be displaced by an adapter unit transversely to the swiveling direction as a function of the boost pressure.
Claims16
A speed governor for internal combustion engines, comprising a fuel-quantity control member;
- a governor sleeve;
- a centrifugal advance device operated for regulating speed and producing a speed-dependent adjustment of said governor sleeve;
- a coupling provided between said governor sleeve and said fuel-quantity control member and enabling an optional change in a fuel injection quantity, said coupling including a control lever provided with a feeler;
- a base support provided with a full-load stop which can be sensed by said feeler of said control lever;
- and added support provided with an added stop and rotatably supported at said base support;
- a governor housing on which said base support is fixed;
- means for fixing said base support on said housing;
- two adjusting stops;
- an actuating member which swivels said added support between said adjusting stops and has a position depending on operating parameters of the internal combustion engine;
- an adapter unit longitudinally displacing said added support transversely to the swiveling direction.
