Abstract:
[Problem] To provide a valve device and a manufacturing method therefor, with which the shape of a plurality of refrigerant passages formed in one valve body can be simplified. [Solution] A high-pressure-side valve body 100 of a high-pressure-side valve device 10 has a high-pressure-side main refrigerant passage 110, a first high-pressure-side branching refrigerant passage 310, and a second high-pressure-side branching refrigerant passage 410. The high-pressure-side main refrigerant passage 110 has a columnar shape extending in a straight line from a main surface 101 toward a rear surface 102 of the high-pressure-side valve body 100. Part of a columnar first high-pressure-side main valve chamber 311 of the first high-pressure-side branching refrigerant passage 310 overlaps the high-pressure-side main refrigerant passage 110. Part of a columnar second high-pressure-side main valve chamber 411 of the second high-pressure-side branching refrigerant passage 410 overlaps the high-pressure-side main refrigerant passage 110.
