値を示す。(a) In the case of normal operation In the case of normal operation, when the manual cock 17 is in the operating position and the temperature and flow rate of the hydraulic fluid A flowing in the main circuit 3 are maintained below the set value, The sub-valve 9 and the pressure reducing valve 18 are both maintained in the open state. As a result, the hydraulic fluid flows through the hydraulic fluid distribution line 8a of the pilot circuit 8, and the main valve 7
The pilot pressure introduced into the pilot chamber 7b exhibits a low value.

開成位置へ復帰する場合もある。Due to circumstances such as strong winds blowing for a long time, if the temperature of the hydraulic fluid A attempts to rise above the set value, the operating rod 11b of the temperature-sensitive actuator 11 will protrude and the spool 9a of the sub-valve 9 will In order to press to the left in the figure,
The sub-valve 9 is switched to the closed position f, and the hydraulic fluid distribution fin 8a of the pilot circuit 8 is cut off. the result,
The discharge pressure of the hydraulic pump 2 acts as the pilot pressure of the main valve 7, and the main valve 7 has a pressure balance acting on the lower part of the valve body 7a. The closed position changes by one. Therefore, the main circuit 8 is cut off, the hydraulic pump 2 stops rotating, and the heat generated by the orifice 41 is stopped. When the temperature of the working fluid A in the main circuit 8 falls, the wax in the temperature-sensitive actuator 11 contracts, and the spool 9a of the sub-valve 9 is returned to the right in the figure by the urging force of the return spring 12, causing the sub-valve 9 returns to the open position. As a result, the main valve 7 is opened to its original state, and the normal heat generation process is resumed. Note that since the switching operation of the sub-valve 9 by the temperature-sensitive actuator 11 is performed gradually within a certain set temperature range, the temperature of the hydraulic fluid A is normal before the main valve 7 is completely closed. In some cases, the main valve 7 returns to the open position.

る。If the flow velocity of the hydraulic fluid A is about to rise above the set value due to a situation such as a strong wind raging at one point, the pressure reducing valve 18 will move one step in the closing direction. Then, the flow rate of the hydraulic fluid distribution line 8a is decreased. As a result, the main valve 7 moves in the closing direction I according to the same principle as described in section mf. A feedback loop is formed by this operation, and the flow rate of the main circuit 3 is maintained at the set limit value regardless of the load on the hydraulic pump 2.

Press 5. As a result, the rotating arm 16 rotates to move the spool 9a of the sub-valve 9 to the left in the figure, the sub-valve 9 switches from the open state to the open state, and the pilot circuit 8 is activated. The liquid flow line 8a is cut off. Therefore, the main valve 7 is switched from the open state to the open state by the same principle IC as described in section (b) above, and when the wind turbine 1 and the hydraulic pump 2 are stopped, the main valve 7 is switched from the open state to the open state. Hydraulic fluid A stops circulation. In this state, the manual cock 17

を確保することもできる。The present invention is to open and close the hydraulic fluid distribution line of the pilot circuit, through which a small amount of hydraulic fluid flows, using a sub-valve and a temperature-sensitive actuator. Since the main valve is operated indirectly to limit abnormal temperature rises in the hydraulic fluid in the main circuit, wind turbines become larger and the flow rate in the main circuit becomes enormous. There is no need to increase the size of the temperature-sensitive actuator for temperature control even if only one thing is achieved. Therefore, the device can be made more compact without compromising reliability of control. Furthermore, since the temperature-sensitive actuator, which constitutes the mechanical operating part, can be made extremely small, a high level of safety can be ensured.
