Title:
DEVICE AND METHOD FOR RECOVERING OPERATION FLUID FROM PIPE IN WHICH THE FLUID IS SEALED
Document Type and Number:
WIPO Patent Application WO/2004/061380
Kind Code:
A1
Abstract:
An operation fluid recovery device has a casing (2) with an insertion opening (3) into which an end portion of a heat pipe (P) can be inserted; a seal member (4) made of an elastic body, provided in the casing (2) and having an insertion hole (4a) through which the end portion of the heat pipe (P) is inserted; a pressing member (5) provided in the casing (2), at the back side of the seal member (4), so as to be movable in a forward/backward direction and pressing the seal member (4) for compression when the pressing member is moved forward; a hydraulic cylinder (6) for moving forward the pressing member (5); and a needle (7) provided in the casing (2), for forming a through-hole in the end portion of the heat pipe (P) inserted in the casing (2). In the pressing member (5) is formed a depression (21) in its front-end surface, and the depression works as an operation fluid recovery space. The operation fluid recovery device is adaptable to operation fluid-sealing pipes with different outer diameters. Further, in the recovery of operation fluid, discharge of the operation fluid to the air can be reduced to a minimum level.
