Abstract
This invention relates to a piezoelectric transducer for generating ultrasonic oscillations, in which a bolt joining two metal elements clamping the transducer elements is constructed as a flushing passage, and to which a curved tubular shaft is connected via an end fitting comprising a passage. The shaft has its internal diameter enlarged as far as beyond the area of its curvature, and the bolt is traversed on the one hand by a plastics material tube connectible to the end fitting and may be connected at the proximal side of the transducer to a flushing pipe.
