Abstract (en)
Mounting arrangement of an ultrasound transducer onto the wall plate of an ultrasound washing tank, wherein the transducer consists of a pair of piezoelectric ceramic disks (2,3), subjected to an electric field variable with an ultrasonic frequency, and of a pair of metallic resonance bodies (4,5) positioned to the sides of said piezoelectric disks (2;3). A first resonance body (5) and two piezoelectric disks (2,3) are mounted externally to the wall plate (1) of the washing tank, while a second resonance body (4) is mounted on the inner side of said wall plate (1), and a bolt (9) axially crosses said bodies (4,5) and disks (2,3) as well as a hole in said wall plate of the washing tank, so as to fix these elements together and onto the wall plate of the tank. A sealing and vibration damping ring gasket (10) is interposed between the inner surface of the wall plate (1) of the washing tank and the surface of the inner resonance body adhering thereto. The size and shape of the resonance bodies are determined so that a central, nodal, vibration plane substantially coincides with the wall plate of the washing tank. <IMAGE>
