    • 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.
    • 用于以微小流量供给流体的结构和基于该结构的流体循环方法。 在该结构中,主体(1)由作为主流路部(4)的第一下属孔(2)沿结构构件的轴向方向钻孔的结构体形成。 作为第二从属孔(3)的切口(24)沿着主流动部分间隔开形成,从而径向穿过主体部分(1)到主流动部分(4)。 在每个切口(24)处,第二流体引导件(22)的环形部分(23a)从穿透部分径向插入第一从属孔(2)中。 作为第一流体引导件(14)的副杆构件(15)沿着第一从属孔(2)的轴向插入到环形部分(23a)中,并且主杆构件(17)插入环中 作为流路分隔部件(19)的部分(23a)被插入。 因此,第一从属孔(2)的内部在轴向上径向分成两部分,从而形成主流体部分(4)和循环流动通道主流动部分(31)。 该结构可用作轴/轴承装置的润滑系统。 在这种情况下,润滑剂从主流动部分(4)被供给到需要它的部分和面,并被收集在循环流动通道主流动部分(31)上以便循环。 该结构也可以用作具有密封热交换部分的热交换器,其中交换器以与上述相同的方式循环各种流体。
