Abstract
A centrifugal governor is proposed which has particular applicability to the rpm-dependent variation of ignition or injection timing in internal combustion engines. The centrifugal governor is comprised primarily of a driving shaft and a driven shaft and of a governor disc removably connected with the driven shaft. One eccentric pair is situated on the governor disc for each flyweight; each eccentric pair is coupled with the driven shaft, which serves as the camshaft of an injection pump and may be rotated by the flyweights articulated on the eccentrics in order to vary the mutual rotary position of both shafts.
Claims10
A centrifugal governor comprising first and second coaxial rotary members between which a driving connection is established such that, in use of the governor, the relative rotational position between the two rotary members varies in accordance with their speed, said first rotary member being in the form of an annular member defining within its periphery a space into which said second rotary member projects, said second rotary member including a bearing flange, the governor further comprising:
- (a) a disc releasably attached to said first rotary member, said disc having plane parallel faces;
- (b) two eccentric pairs, each comprising an adjusting eccentric and a compensating eccentric, the adjusting eccentric being mounted for rotation in said disc and the compensating eccentric being mounted for rotation in the adjusting eccentric, the compensating eccentric being articulatedly connected to said flange by a pin mounted at an eccentric position on the compensating eccentric;
- and
- (c) two flyweights, each articulatedly connected to a respective adjusting eccentric by, on the side thereof facing away from said flange, a pin mounted at an eccentric position on the adjusting eccentric.
