ABSTRACT:
An operating mechanism for a fluid blast circuit interrupter which is actuated by a single drive shaft and includes a toggle linkage for opening and closing the breaker contacts, and a cam and rachet assembly for opening and closing a gas supply valve. Upon initiation of an opening or closing operation, the cam is coupled to the drive shaft and rotated to open a normally closed, spring loaded, gas valve before the interrupter contacts are opened or closed, and to charge a cam return spring. After the interrupter contacts are fully opened or closed, the cam is disengaged from the drive shaft and returned to its neutral position by its return spring to allow the gas valve to reclose.
