Abstract

Provided is a fluidic device including a first fluid unit having a plurality of first passages for passing fluids along a first direction, a second fluid unit having a plurality of second passages for passing the fluids along a second direction intersecting the first direction, and a plurality of on/off valves placed at a plurality of points, one at each point, where the first passages and the second passages intersect with each other. The first fluid unit and the second fluid unit are arranged such that outlets formed at a plurality of locations of the first passages are coupled to inlets formed at a plurality of locations of the second passages at each of the points.

First claim

1 . A fluidic device comprising:
a first fluid unit having a plurality of first passages for passing fluids from a plurality of supply sources each along a first direction; a second fluid unit having a plurality of second passages for passing the fluids along a second direction intersecting the first direction and supplying the fluids to a plurality of destinations; and a plurality of on/off valves placed at a plurality of intersecting points, one at each intersecting point, where the first passages and the second passages intersect with each other, the on/off valves switching flow states of the fluids from the first passages to the second passages, wherein the first fluid unit and the second fluid unit are removably coupled to each other such that outlets formed at a plurality of locations of the first passages are coupled to inlets formed at a plurality of locations of the second passages at each of the intersecting points.

2 . The fluidic device according to claim 1 , wherein
the first fluid unit includes a plurality of first passage members each having one of the first passages, and the second fluid unit includes a plurality of second passage members each having one of the second passages.

3 . The fluidic device according to claim 2 , further comprising an assembly including an annular shaped annular portion and a plurality of nut portions spaced along a circumferential direction of the annular portion,
wherein the plurality of nut portions are inserted into insertion holes opening on an upper surface or a lower surface of the corresponding second passage member, a plurality of first fastening bolts are fastened to one end sides of the nut portions, the first fastening bolts being inserted through through holes formed at each of the corresponding first passage member and the corresponding second passage member, and a plurality of second fastening bolts are fastened to the other end sides of the nut portions, the second fastening bolts being inserted through through holes formed at each of the corresponding on/off valve and the corresponding second passage member.

4 . The fluidic device according to claim 2 , further comprising a plurality of pressure sensors mounted on destination side end portions of the plurality of second passage members, one on each destination side end portion, the pressure sensors each detecting a pressure of a fluid supplied from the corresponding second passage to the corresponding destination.

5 . The fluidic device according to claim 3 , further comprising a plurality of pressure sensors mounted on destination side end portions of the plurality of second passage members, one on each destination side end portion, the pressure sensors each detecting a pressure of a fluid supplied from the corresponding second passage to the corresponding destination.
