The apparatus can also remove the oil-separation phenomenon even if the apparatus is used for a long time by effecting a pumping operation for suction and discharge of the lubricating oil by the pressure of a flanger ascending and descending by a mechanical driving force, and thus not applying a high pressure to a lubricating oil pouch.

Abstract: A depression container comprises a vessel including a compartment and a cover for enclosing and thus sealing the compartment.
