Abstract:
PROBLEM TO BE SOLVED: To provide a constant flow valve which can stabilize a flow rate.SOLUTION: A constant flow valve 1 changes a flow passage area in accordance with a pressure in a water supply passage 82 being a primary side flow passage, so as to adjust flow rates in water supply passages 83 and 86 being secondary flow passages to a constant flow rate. The piston 2 is pushed into a cylinder 3 by a pressure in the water supply passage 82. Throttle parts 4a and 4b are narrowed in their flow passage areas due to the piston 2 being pushed. A pressure adjustment chamber 31 is surrounded by the cylinder 3 and a bottom portion 21 of the piston 2, and the pressure in the pressure adjustment chamber 31 is raised due to the piston 2 being pushed.SELECTED DRAWING: Figure 3
