Title:
PIEZOELECTRIC ELEMENT-DRIVEN VALVE AND FLOW VOLUME CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159959
Kind Code:
A1
Abstract:
Provided is a piezoelectric element-driven valve 100 configured to be able to control a fluid having a temperature exceeding a use range temperature of a piezoelectric actuator. The piezoelectric element-driven valve 100 comprises: a piezoelectric element 10b for causing a valve body 2 to be separated from or seated on a valve seat 5; a heat-insulating spacer 40 disposed between the valve body 2 and the piezoelectric element 10b; and a distortion sensor 20 fixed to the piezoelectric element 10b. The heat-insulating spacer 40 has a plurality of holes 40H penetrating therethrough in a direction intersecting a stacking direction D1 of the heat-insulating spacer 40 and the piezoelectric element 10b.
