Governor system for engine starter mechanism

A governor system, for engine starter mechanisms including:

• a gear shaft connected to and driven by a motor for rotation;
• a single-direction rotatable clutch operatively engaged with the gear shaft via a helical spline such that the clutch rotates together with the gear shaft when the gear shaft is driven to rotate and the clutch moves forward axially along the gear shaft due to angular momentum to transmit the rotation of the gear shaft via a pinion gear disposed at a front end of the clutch to the engine, thereby starting the engine, and when the gear shaft is inactive, the clutch rotates only in an idling manner without transmitting the rotation,
• the governor system for preventing a premature retracting movement of the clutch, comprising:
• an integral governor weight fixed axially relative to the gear shaft and movable in a radial direction relative to the gear shaft due to a centrifugal force caused by the rotation of the gear shaft;
• and a resilient position-restoring device urging said governor weight to an initial retracted position when the centrifugal force diminishes;
• said governor weight having an annular shaped body in which a base portion of the clutch is received when the governor weight is in the initial retracted position, and the base portion of the clutch being movable into and out of the annular shaped body in the axial direction parallel to the gear shaft;
• and
• said governor weight having a center of gravity that is eccentric or located off the central axis of the governor weight in one radial direction so that the centrifugal force of rotation causes the governor weight to shift in said one radial direction, and thus a portion of the governor weight that is disposed at a side opposite to said one radial direction moves toward the gear shaft thereby preventing the premature axial retracting movement of the clutch.
