  • Publication number: 20220316617
    Abstract: Provided is a piezoelectric actuator that can reduce a risk of air leakage due to weakening of pressing force of a valve element against a valve seat surface and airtightness. The piezoelectric actuator is used for a piezoelectric valve that opens and closes a valve utilizing displacement of a laminated piezoelectric element. The piezoelectric actuator includes: a valve element; a laminated piezoelectric element that generates a driving force, required for operation of the valve element, as a displacement; and a displacement enlargement mechanism that enlarges a displacement of a laminated piezoelectric element and causes the enlarged displacement to act on the valve element. In the piezoelectric actuator, a surface of the valve element to be in contact with a valve seat of the piezoelectric valve is made flat and smooth in a state in which a tensile load is applied to the laminated piezoelectric element.
