Abstract

PURPOSE: To produce frictional force for blocking operation as necessary by providing an initial setting element of a connection pin for a control link.
CONSTITUTION: An initial setting element 4a is assembled into a control link 4b and is provided with a connection pin 9a. In normal operation, the connection pin 9a, placed at the initial setting element 4a, transmits the force to drive a guide vane, which is produced by a serbomotor. After a week point is broken down, hydraulic force applied on the guide vane makes the connection pin disconnect from the initial setting element 4a to move on the connection link 4b. With a plate spring 3 applied with load, the hydraulic pressure of the guide vane causes the frictional force enough to block the rotation of the guide vane. A certain frictional force is determined by adjusting the connection pin moving on the control link 4b
