Abstract
PURPOSE: To stop oil leakage when it occurs and to continue operation by providing an oil hydraulic pilot changeover value operated by a controller.
CONSTITUTION: When oil leakage is detected by the fact that the discharge pressure of any auxiliary oil hydraulic pump 25 comes under the limit value or that the oil level of tanks 20, 21 comes under the limit value, by a controller is shut a connection valve 33, two rudder shaft turning devices 12, 13 are cut out and both rudder shaft turning devices 12, 13 are driven independently for a given time. When the discharge pressure of one of the Pumps 25 does not exceed the limit value or when one oil level of the oil tanks 20, 21 comes under the limit value, oil leakage is decided to have occurred on the same side at one of the devices 12, 13, the bypass valve 30 on that side opens, the pumps 19, 25 stop and operation is continued only by the corresponding one of the rudder shaft turning devices 12, 13.
