Abstract: A governor valve assembly is disclosed for automatic transmission units including first and second valve members which are provided in a rotating governor body so as to be telescopically fitted together. The first and second valve members are arranged on diametrically opposite sides of the rotating axis of the governor body, and cooperate with one another so that when the rotating speed of the governor body reaches a preselected level, a governor pressure is produced and delivered from the assembly.
