FIELD: machine building.
SUBSTANCE: device increasing force of drive with locking device is described. The described system of jet control contains a first jet control device for connection by means of the fluid of the control fluid source and control drive via the first bypass channel. The control fluid source ensures the control fluid to move the actuator of the control drive in the first direction or in the second direction opposite to the first direction, when the control drive is in operable state. The second jet control device is connected by the fluid with the first jet control device and is arranged fort connection by means of the fluid of the locking drive and control drive via the second bypass channel, when the control drive is in off state. The locking drive is functionally connected with the control drive.
EFFECT: higher reliability of the device.
