Abstract
A governor device comprises a first lever connecting a governor lever to a rotary speed setting lever interlockingly, a second lever pivotally supported by the first lever, and a third lever pivotally supported by the second lever, regulated its rotation amount by the second lever and interlocked with a governor weight. A fuel injection compensation spring is provided between the first lever and the second lever so as to bias them for decreasing the rotary speed for a fixed amount at the time of low speed rotation. A compensation starting rotary speed setting device, which is a set load changing means for the fuel injection compensation spring, is provided on the first lever near the fuel injection compensation spring.
Claims20
A governor device comprising:
- a first lever interlockingly connected to a rotary speed setting lever;
- a second lever pivotally supported by the first lever;
- a third lever pivotally supported by the second lever, its rotation amount regulated by the second lever and interlocked with a governor weight;
- an elastic member provided between the first lever and the second lever so as to bias the levers for decreasing a rotary speed of an engine for a fixed amount at a time of low speed rotation;
- and
- a set load changing means for the elastic member attached to the first lever near the elastic member.
A governor device comprising:
- a first lever interlockingly connected to a rotary speed setting lever;
- a second lever separate from and pivotally supported by the first lever;
- a third lever pivotally supported by the second lever, its rotation amount regulated by the second lever and interlocked with a governor weight;
- an elastic member provided between the first lever and the second lever so as to bias the levers for decreasing a rotary speed of an engine for a fixed amount at a time of low speed rotation;
- and
- a set load changing means for the elastic member attached to the first lever near the elastic member.
