Abstract

PURPOSE: To make the piping of the emergency stopping device and the device itself compact by using a bearing lublicating oil on a rotative shaft of the hydraulic machine as the oil source of an oil hydraulic pump.
CONSTITUTION: When an oil hydraulic pump 2 is driven in a defective state of a pressurized oil source, that is, under an emergency stop condition, the lublicating oil stored in a bearing lublicating oil tank 4 of a rotative shaft 17 of the hydraulic machine is pumped up through a pump-up duct 3 to forcibly open a check valve 12 and be supplied to an oil hydraulic pilot duct 13 for switching a pressure distributor 7. As a result, a discharge duct 10 and a closing side duct 9b of a water inlet valve operation servo-motor 6 are communicated with each other, while at the same time an opening side duct 8 and a discharge duct 11 are communicated with each other. The pressurized oil discharged from an oil hydraulic pump 2 is supplied to a closing side cylinder of a servo-motor 6, while an opening side cylinder causes discharge of a fluid tank 4. Further, with switching of a pressure distributor ducts 8a and 9a are blocked within the pressure distributor 7 to separate the servo- motor 6 from a governer 5 and a pressurized fluid sorce 16 connected thereto.
