Abstract
A governor mechanism is mounted for rotation with a drive shaft about an axis, has one or more reaction nozzles for imparting rotational movement to the drive shaft, and one or more valve portions supported for radially directed sliding movement between first and second radially spaced positions for purposes of controlling flow of pressurized fluid to the nozzles and thus the rotational speed of the drive shaft. The valve portions are formed integrally with a ring-shaped mounting portion fabricated from resiliently deformable material. In alternative constructions, similar governor mechanisms are co-axially mounted with vane motors by a common drive shaft and the mechanisms employed to control flow of pressurized fluid to the vane motor.
