In addition, the pressure sensing module 600 is coupled to at least one of the front and rear and both sides of the driving body 210 so as not to interfere with the hydraulic actuator 100, the driving valve 140, and the flow sensing module 500. .

In the first example of the present invention, the drive valve 140 may be configured as a servo valve. Then, as illustrated in FIG. 3, the monitoring driving block 200 may include a driving dummy part 243 corresponding to the driving dummy port of the servovalve. The opening of the first-first driving passage 211a, the opening of the second driving passage 212, the opening of the third driving passage 213, and the driving dummy portion 243 are respectively coupled to the side of the hydraulic actuator 100.

Similarly, the opening of the first-second driving passage 211b, the opening of the second driving passage 212, the opening of the third driving passage 213, and the driving dummy portion 243 are quadrangles, respectively. It is to be formed corresponding to the vertex of.

The monitoring drive block 200 according to the first example of the present invention is branched from the first-second driving path 212b as shown in FIG. 3, and driving pilot flow path 253 for delivering hydraulic oil to the driving valve 140. It may further include. The hydraulic fluid delivered through the drive pilot channel 253 provides the pilot pressure to the servovalve.

Then, since the pressure sensing module 600 may be coupled to the first driving auxiliary passage 251 or the second driving auxiliary passage 252, even if the hydraulic actuator 100 is in operation, the pressure of the hydraulic oil supplied to the hydraulic actuator is increased.

The flow rate of the working oil can be monitored in real time. In addition, since the pressure sensing module 600 is coupled to the first-first driving pressure passage 231a and the first-second driving pressure passage 231b, the hydraulic actuator 100 is supplied to the hydraulic actuator 100 even when the hydraulic actuator 100 is in operation. The pressure of the working oil can be monitored in real time.

For example, when the first-second driving passage 211b and the second driving passage 212 are connected according to the operation of the driving valve 140, the working oil sequentially turns the second driving passage 212 and the operating line 103. Since it is transmitted to the cylinder hydraulic chamber 111 formed on one side of the piston 120, it is possible to slide the piston 120 in the forward direction.

Here, since the pressure sensing module 600 is coupled to the second driving pressure passage 232, the pressure of the hydraulic oil supplied to the hydraulic actuator 100 may be monitored in real time even when the hydraulic actuator 100 is in operation.

As another example, when the first-second driving passage 211b and the third driving passage 213 are connected according to the operation of the driving valve 140, the working oil sequentially turns the third driving passage 213 and the return line 104. Since it is transmitted to the cylinder hydraulic chamber 111 formed on the other side of the piston 120, it is possible to slide the piston 120 in the reverse direction. In this case, the hydraulic fluid may be delivered to the cylinder hydraulic chamber 111 formed on the other side of the piston 120 through the third driving passage 213, the return line 104, and the oil discharge chamber 170.

As another example, the first-second driving passage 211b may be closed according to the operation of the driving valve 140, and the second driving passage 212 and the third driving passage 213 may be connected. Then, the hydraulic oil of the cylinder hydraulic chamber 111 formed on one side of the piston 120 passes through the operation line 103, the second driving passage 212, the third driving passage 213, and the return line 104. Since it is transmitted to the cylinder hydraulic chamber 111 formed on the other side of the piston 120, it is possible to slide the piston 120 in the reverse direction.

Since the pressure sensing module 600 may be coupled to the third driving pressure passage 233, the pressure of the hydraulic oil supplied to the hydraulic actuator 100 may be monitored in real time even when the hydraulic actuator is in operation.
