Abstract

PURPOSE: For making a construction so that the temperature rise of oil may be suppressed, to increase the heat radiation of tanks by increasing the surface area of said tanks with said tanks divided in a plurality or a plurality of pipes provided through said tanks.
CONSTITUTION: An oil 2 filled tank 21 is constructed of four unit tanks 21a. Two of said unit tanks 21a are placed to face other two, thereby forming a regular square. Adjacent ones of said unit tanks 21a are interconnected by pipes 22. A required one of said unit tanks 21a is provided with a pump 3. Said pump 3 is connected to the cylinder of a not-illustrated jack by a main pipe 7 having a flow control valve 5 on the medium portion. By thus constructing said tank 21 of said four unit tanks 21a, the heat radiation rate thereof is increased two times so that the temperature rise of oil can be suppressed.
