Abstract: A governor valve assembly for use with an automatic transmission is rotatably mounted on the output shaft of the transmission and is secured against axial displacement along the shaft. The valve assembly includes at least one chamber having an inlet port for introducing a pressurized fluid medium into the valve assembly and an outlet port for supplying the pressurized fluid medium at governor pressure to the automatic transmission. A combination of a valve member and an assembly of weights and springs is arranged within the chamber so that, as the output shaft rotates at increasing speeds, variable centrifugal forces are developed by the assembly of weights and springs and the position of the valve member is regulated to determine the governor pressure supplied to the output port. The valve member can be formed as one of the weights or as a separate valve spool. The assembly of weights and springs consists of at least three different weights and at least two different springs with each spring extending between a different pair of weights. Accordingly, by means of the arrangement of the weights, it is possible to change the governor pressure in three steps.
