Abstract
In an oil suction system for drawing up oil stored in an oil reservoir through a strainer, the oil reservoir is constructed such that, when the liquid surface of the oil is inclined due to movement of the stored oil, the level of the liquid surface close to the suction port varies in accordance with a plurality of directions of inclination of the liquid surface, and the level of the liquid surface close to the suction port is lower in a particular direction as one of the directions of inclination of the liquid surface than those in the other directions of inclination, and an inflow resistance portion is provided at a lowered liquid-level side of the suction port on which the liquid level is lowered when the oil surface is inclined in the particular direction, for increasing the resistance to flow of the oil from the lowered liquid-level side toward the suction port, to be larger than the resistance to flow of the oil from a raised liquid-level side of the suction port on which the liquid level is raised due to inclination in the particular direction, toward the suction port.
