After a predetermined time elapses until the hydraulic system 40 is filled with the working oil, only the lubrication gun 1 is switched to the low vacuum source and connected, and in this state, the lubrication gun 1 is moved from the opening of the master cup C through the opening. Then, each vacuum gun 2 is removed from each air bleeder valve V. That is, after the predetermined time has elapsed, the control device of the control panel 36 selectively switches only the switching valve 9A of the first switching valve group shown in FIG. 1 to the solenoid operating position by the timer function. At that time, the control device issues an alarm such as a buzzer in order to notify the worker of the switching control. Then, by this switching control, the lubrication gun 1 is moved from the lubrication hose 24 to the pipeline P1.
3 and the low vacuum tanks 4 and 4 are connected to the low vacuum tanks 4 and 4 via the low vacuum line P3, and the vacuum guns 2 are kept connected to the low vacuum tanks 4 and 4. Therefore, the operator removes the lubrication gun 1 from the opening of the master cup C and removes each vacuum gun 2 from each air bleeder valve V in a procedure opposite to the procedure described above. In this case, the working oil in the lubrication gun 1 and the working oil in the vacuum gun are sucked into the low vacuum tanks 4 and 4 to prevent overflow from the lubrication gun 1 and the vacuum gun 2.

When the first switching valve group switches and connects the lubrication gun to the oil supply pump, and the second switching valve group switches and connects the vacuum gun to the low vacuum tank, the opening of the master cup is connected to the oil supply pump, and the air is supplied to the air supply pump. Since the bleeder valve is connected to the low vacuum tank, the hydraulic oil in the vehicle is quickly filled with the working oil via the oil supply pump. The first switching valve group switches and connects only the lubrication gun to the low vacuum tank, and the second switching valve group removes the lubrication gun from the opening of the master cup while the vacuum gun remains connected to the low vacuum tank.
When the vacuum gun is removed from the air bleeder valve, the working oil in the lubrication gun and the working oil in the vacuum gun are sucked into the low vacuum tank.

Therefore, according to the hydraulic oil filling apparatus for a vehicle of the present invention, the inside of the hydraulic system of the vehicle can be quickly and reliably brought into a vacuum state, and the hydraulic oil can be quickly and reliably supplied to the hydraulic system. Can be filled. In addition, it is possible to prevent the overflow of the working oil in the lubrication gun and the vacuum gun.
