<P>PROBLEM TO BE SOLVED: To provide a lubricating device capable of suppressing variation of height of an oil surface in an oil storage part and reducing oil usage. <P>SOLUTION: As consistency of oil 17 decreases and a return amount of the oil 17 returned from a lubricated part 20 to an oil pan 10 by a returning pipe 12 increases according to rise in temperature of the oil 17, a storage amount of the oil 17 increases in the oil pan 10, and the height of the storage part oil surface which is the oil surface in the oil pan 10 rises. Here, as a piston 14 is slid to an oil non-introducing room 13a side by an actuator 15 according to rise in temperature of storage-part oil which is the oil 17 stored in the oil pan 10, a volume of an oil introducing room 13b increases, and the storage-part oil is introduced to the oil introducing room 13b. As an increased amount of the volume of the oil introducing room 13b is equivalent to a decreased amount of a volume of the oil non-introducing room 13a, an increased amount of the return amount is absorbed to the oil non-introducing room 13a positioned below the storage part oil surface. <P>COPYRIGHT: (C)2010,JPO&INPIT |
