<p>PURPOSE:To facilitate the depth adjustment of oil in an oil quantity adjusting device of an oil tank, in which the oil is circulated so as to be purified by an oil purifier located below the tank, by constituting a system such that the oil within the oil tank flows into the purifier via an oil quantity adjusting pipe, a vessel within the oil tank, and an outlet pipe. CONSTITUTION:In an oil tank 1, a vessel 31 of an oil quantity adjusting device 30 is supported against a side wall 6 of the oil tank 1 by a support 33 in such a manner that an opening part 32 of the vessel 31 is open to the upper space of a normal oil surface 8 of the oil tank 1 and that the vessel 31 is lower than the oil surface. Meanwhile, a suction pipe 34 is provided in such a manner that it penetrates the bottom plate 35 of the vessel 31 and is open or facing a bottom plate 15 of the oil tank 1. In addition, an oil quantity adjusting pipe 36 is threadedly engaged with the upper part of the suction pipe 34 in such a way that the height of the pipe 36 can freely be adjusted. On the other hand, an outlet pipe 40 penetrates the bottom plate 35 of the vessel 31 to extend itself downward and penetrates the side wall 6 of the oil tank 1, and then it is connected to an oil purifier 20. With this contrivance, the pressure within the vessel 31 is balanced with that pressure within the oil tank 1, so that the level of the oil surface 41 within the vessel 31 becomes the same as that of the normal oil surface 8 within the oil tank 1.</p> |
