Title:
SWITCHING VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/016091
Kind Code:
A1
Abstract:
In a switch valve device, two ceramic discs (51, 52) of a first valve mechanism (50) are arranged on one side of a valve device body in the axial direction such that switching can be made freely between a first water flow position for communicating a first water flow inlet and a first water flow outlet, and a position for interrupting communication. On the other hand, two ceramic discs (61, 62) of a second valve mechanism (60) are arranged on the other side of the valve device body in the axial direction such that switching can be made freely between a second water flow position for communicating a second water flow inlet and a third water flow outlet, and a position for interruption communication. The first valve mechanism (50) and the second valve mechanism (60) are rotary operated in synchronism by means of a handle (70) such that the second valve mechanism (60) is switched to the interruption position when the first valve mechanism (50) is at the first water flow position, and the first valve mechanism (50) is switched to the interruption position when the second valve mechanism (60) is at the second water flow position.
