In a hydraulically actuated device configured to
The respective drive circuits of the two sets of solenoid valves are connected by a unidirectional conduction circuit, and when the solenoid valve drive circuit on the lubricating oil inflow side fails to the side that opens the solenoid valve, the solenoid valve drive circuit on the lubricant oil outflow side is connected. The hydraulic system is characterized in that the solenoid valve drive circuit on the lubricant oil outflow side operates as it is, and when the solenoid valve drive circuit on the lubricant oil outflow side fails to open the solenoid valve, the operation of the solenoid valve drive circuit on the lubricant oil inflow side stops. Actuation device safety device.
