Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/125774
Kind Code:
A1
Abstract:
Provided is a valve device (1) with which the temperature and flow rate of hot or cold water discharged from a water mixing faucet can be adjusted and with which it is also possible to reduce the cost and size of a water faucet device. The valve device (1) is provided with an external cylinder (2) and an internal cylinder (10) that is disposed inside the external cylinder (2). The external cylinder (2) has a first fluid-side inlet (3), a second fluid-side inlet (4), and a mixed fluid-side outlet (5). The internal cylinder (10) has a first fluid-side opening (12) corresponding to the first fluid-side inlet (3) and a second fluid-side opening (13) corresponding to the second fluid-side inlet (4). A first fluid-side flow path (14) and a second fluid-side flow path (15) are formed by rotation of the internal cylinder (10). The valve device (1) is formed so that, within a range of rotation of the internal cylinder (10) where the cross-sectional area of the first fluid-side flow path (14) and the cross-sectional area of the second fluid-side flow path (15) change, the sum of the cross-sectional area of the first fluid-side flow path (14) and the cross-sectional area of the second fluid-side flow path (15) is constant, or the ratio between the cross-sectional area of the first fluid-side flow path (14) and the cross-sectional area of the second fluid-side flow path (15) is constant.
