Abstract
An ultrasonic atomizing transducer assembly includes cylindrical front atomizing and rear dummy sections clamped to a sandwich of an annular electrode between two annular piezoelectric disks by a central tubular bolt. Liquid to be atomized enters the rear of the transducer assembly through a feed tube forming a rearward extension of the central bolt and flows through an axial passage to exit onto an atomizing surface on the tip of an amplifying probe extending from the front end of the front cylindrical section. An annular sealing member disposed between a sealing surface at the front end of the bolt and the passage prevents liquid flowing through the passage from contacting the inner surfaces of the piezoelectric disks. To protect the outer surfaces of the piezoelectric disks, an enclosed shell surrounds and supports the transducer via O-rings loaded purely in radial compression.
