Title:
STRUCTURE FOR FEEDING FLUID AT A MINUTE FLOW RATE AND METHOD FOR CIRCULATING FLUID BASED ON THE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2004/022990
Kind Code:
A1
Abstract:
A structure for feeding fluid at a minute flow rate and a method for circulating fluid based on the structure. In the structure, a main body (1) is formed from a structural member where a first subordinate hole (2) as a main flow portion (4) is bored in the axial direction of the structural member. Cut-outs (24) as second subordinate holes (3) are formed with spacing along the main flow portion so as to radially penetrate the main body portion (1) to the main flow portion (4). At each of the cut-outs (24), a ring portion (23a) of a second fluid guide (22) is radially inserted in the first subordinate hole (2) from the penetration portion. A secondary rod member (15) as a first fluid guide (14) is inserted in the ring portion (23a) in the axial direction of the first subordinate hole (2), and a main rod member (17) is inserted in the ring portion (23a) as a flow passage-dividing member (19) is being inserted. Thus the inside of the first subordinate hole (2) is radially divided into two in the axial direction, so that the main flow portion (4) and a circulation flow passage main flow portion (31) are formed. The structure can be used as a lubrication system for a shaft/bearing device. In this case, a lubricant is fed from the main flow portion (4) to portions and faces that require it and collected at the circulation flow passage main flow portion (31) for circulation. The structure can also be used as a heat exchanger with a sealed heat-exchanging portion, in which exchanger various kinds of fluid are circulated in the same way as above.
