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.

Abstract: A coaxial tube elbow has an external electric conductor tube (10) housing an internal electric conductor (20) inside and bend sections (12, 21D) formed by bending the external electric conductor tube and the internal electric conductor at a predetermined angle. The vertical section of the external electric conductor tube (10) is an arc shape at the bend section (12). The vertical section of the bend section (21D) of the internal electric conductor (20) is preferably of a partially notched arc shape. In the manufacturing of the external electric conductor tube (10), low melting point metal is filled into the external electric conductor tube of a straight shape and then the tube is bent in a metal mold. After the bending, low melting point metal is melt and removed by heating, whereby a bent external electric conductor tube (10) can be obtained. Thus the coaxial tube elbow with fewer parts allowing assembly without the use of brazing can be obtained.
