<p>PURPOSE:To suppress variation in the level in a tank body to the possible minimum extant. CONSTITUTION:An oil restraining plate 20, obtained by forming a plate body of a specified width in a frame shape, is fixed to the interior wall surface of four peripheries of a tank body 11a by means of welding or the like in plural number of stages in suck a manner that the plate surface may be parallel to the fluid level. When the return oil flows into the tank body 11a through a return oil induction inlet 15, its flow is braked due to its contact with the oil restraining plate 20 whereby tropping of air is restrained to the minimum and agitation of operating fluid is also restrained to the minimum. Air bubbles floating in the operating fluid come in contact with the oil restraining plate 20, caught and removed. Furthermore, even if the operating oil tank 11 is tilted, the operating oil sticks to the oil restraining plate 20 because the operating oil has a certain degree of viscosity and if even the operating fluid tank 11 is oscillated or fluctuated from the tilted state, the oil level may not make any big swing or wave.</p> |
