Patent ID: 8839818

Claim:
A valve device configured to adjust flow volumes of a plurality of fluids for adjusting temperature of an electronic device under test, the valve device comprising: a plurality of flow paths through which the fluids are able to flow, the plurality of flow paths comprising: a first flow path; a second flow path adjacent to the first flow path; a third flow path adjacent to the second flow path; a fourth flow path; a fifth flow path adjacent to the fourth flow path; and a sixth flow path adjacent to the fifth flow path; and a merging section into which the plurality of flow paths merge, wherein: the merging section has a rotary body provided rotatably inside the merging section, a first channel is formed in a circumferential surface of the rotary body, a second channel is formed in the rotary body, the rotary body makes the first channel face at least two flow paths among the plurality of flow paths so as to connect the at least two flow paths, the first channel has a first opening width that is tapered at the ends of the first channel, the first opening width is along a rotational axis of the rotary body, and the rotary body can rotate among: a first rotary position where the first channel faces the first flow path and the second flow path, and where the second channel faces the fourth flow path and the fifth flow path, a second rotary position where the first channel faces the first flow path, the second flow path, and the third flow path, and where the second channel faces the fourth flow path, the fifth flow path, and the sixth flow path, and a third rotary position where the first channel faces the second flow path and the third flow path, and where the second channel faces the fifth flow path and the sixth flow path.
