More Information
Summary:PURPOSE: A piezoelectric valve is provided to increase generation force and the bending displacement of a piezoelectric actuator by extending one surface in the opposite side to a surface where the displacement occurs to support the piezoelectric actuator. CONSTITUTION: A piezoelectric valve comprises a housing(10), a piezoelectric actuator(20), and a pressing part(30). The housing comprises a hole and a flow path. Air flows in or out through the hole and is moved through the flow path. One end of the piezoelectric actuator is fixed in the housing by a fixing member and the other end thereof is supported by the housing. The pressing part presses the other end of the piezoelectric actuator at a constant pressure.
