Abstract:
PROBLEM TO BE SOLVED: To provide a valve structure capable of highly accurately controlling a flow rate in starting flowing fluid.SOLUTION: A valve structure includes: a valve seat 3 formed with two outflow ports 3a for outflowing fluid; and a valve body 4 provided so as to be rotatable to the valve seat 3, and configured to adjust opening of the outflow port 3a. The valve body 4 has a flow control groove 4d along a circumferential direction, whose area overlapping with the outflow port 3a is changed by rotation. A center of the outflow port 3a is displaced from a rotation locus of a tip part 4b of the flow control groove 4d starting overlapping with the outflow port 3a with rotation of the valve body 4.SELECTED DRAWING: Figure 7
