ABSTRACT:
The output rotation of an automatic transmission is transferred to a flyweight to rotate it. A spool is depressed in an axial direction under the centrifugal force of the flyweight, generating a governor hydraulic pressure corresponding to the rotational speed of the flyweight. Some of the governor pressure is fed back to the spool. The force in the direction opposite to the pressing force generated by the flyweight is applied to the spool, thereby balancing the spool. A spring enclosing chamber communicating with the outside is formed serially in the axial direction of the spool and separately from the feedback hydraulic pressure. A force in the direction opposite to the pressing force of the flyweight is exerted on the spool by the spring disposed in the spring enclosing chamber, thereby establishing a breakpoint at which generation of the governor hydraulic pressure occurs.
