Accordingly, the hydraulic fluid is not circulated and discharged only once when passing through the cooling tube 110, but is circulated after being circulated three times and returned. Accordingly, it is possible to increase the cooling efficiency by increasing the time during which the hydraulic fluid stays in the cooling tube 110.

Specifically, the hydraulic fluid is supplied to the cooling tube 110 through the first space A1, and the hydraulic fluid circulated in the cooling tube 110 passes through the second space A2. To the cooling tube (110). Then, the second circulated hydraulic oil is supplied to the third space A3, and then is supplied to the cooling tube 110 again.

Thus, the hydraulic oil, which is thirdly supplied to the cooling tube 110 in the three spaces, is circulated and discharged through the outlet 120b in four spaces.

Here, the first space A1 is communicated with a part of the second space A2 by the cooling tube 110, and the remainder of the second space A2 is communicated with the cooling tube 110 by the cooling tube 110, And communicates with a part of the third space A3.

And the remainder of the third space A3 is communicated with the fourth space A4 by the cooling tube 110. [

The hydraulic fluid supplied to the first space A1 passes through the third space A3 and the fourth space A4 to circulate the cooling tube 110 to the outside after the third circulation .

As described above, the connection part 120 according to the present invention divides the flow space into four spaces, thereby increasing the time during which the hydraulic oil stays in the cooling tube 110, thereby increasing the cooling efficiency of the hydraulic oil.

As described above, the preferred embodiments of the present invention have been described, and the present invention can be embodied in other forms without departing from the spirit or scope of the present invention. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and thus the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
