Document Type and Number:
Japanese Patent JP6613101
Kind Code:
B2
Abstract:
In order to prevent discharge of bubbles near a bottom surface of a tank, a first discharge tube (31) having a substantially cylindrical shape with openings at both ends is inserted through an outflow hole (10c) of a filter case (19) and provided protruding toward the bottom surface of the tank. A second discharge tube (32) having a substantially cylindrical shape is provided so as to cover the first discharge tube (31). The second discharge tube (32) includes a first end (32a) that comes into contact with a bottom surface (10b) of the filter case (19), and is provided protruding from the bottom surface (10b) of the filter case (19) toward the bottom surface of the tank. A tip end (32b) of the second discharge tube (32) is covered by a bottom surface cover (32c), and a plurality of discharge holes (32d) are formed in a region near an upper end of a side surface. As a result, oil discharged from the outflow hole (10c) flows downward through the first discharge tube (31), then flows upward between the first discharge tube (31) and the second discharge tube (32), and is discharged from a region near an upper end of the second discharge tube (32).
