Title:
VALVE DEVICE AND PUMP DEVICE
Document Type and Number:
Japanese Patent JP2017106493
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a valve device capable of properly controlling flow of transfer fluid in which a material object is mixed.SOLUTION: A valve device includes an inflow passage 2 to which transfer fluid flows in, an outflow passage 3 from which the transfer fluid flows out, and a valve element 4 disposed between the inflow passage 2 and the outflow passage 3. The valve element 4 has a valve chamber 17 communicating with the inflow passage 2 and the outflow passage 3. A deformation valve member 18 elastically deformable is disposed inside of the valve chamber 17 in a state of being airtightly fixed at both end portions. The valve chamber 17 has an air supply/discharge portion 26 for supplying and discharging the air to an airtight part, to the deformation valve member 18. The deformation valve member 18 is operated to be elastically deformed and restored by supplying and discharging of the air by the air supply/discharge portion 26, to switch the valve chamber 17 to a passing state in which a material object can pass with the transfer fluid, and a restriction state in which the passing of the material object is restricted.SELECTED DRAWING: Figure 1
