<P>PROBLEM TO BE SOLVED: To provide a residual oil recovery device which can suppress reduction of circulated lubricating oil and eliminating time for returning a residual lubricating oil sucked from the inner part of a rotary machine to the circulation passage of a lubricating oil. <P>SOLUTION: In an oil circulation recovery device 10, the lubricating oil is supplied to the bearing of a rotor 5 while being circulated when the rotor 5 of the rotary machine 3 is rotated and the residual lubricating oil remaining in the rotary machine 3 can be recovered when supply of the lubricating oil to the bearing is stopped. The oil circulation recovery device includes an oil circulation device 19 supplying the lubricating oil to the bearing of the rotor 5 while circulating the lubricant oil when the rotor 5 of the rotary machine 3 is rotated and a sucking device 21 sucking the residual lubricating oil in the inner part of the rotary machine 3 when supply of the lubricating oil to the bearing 7 is stopped. The sucking device 21 is assembled in the circulation passage to constitute a part of the circulation passage in which the lubricating oil is circulated by the oil circulation device 19 and sends out the sucked residual lubricating oil on a downstream side in the circulation direction of the circulation passage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
