Ultrasonic water jet having electromagnetic interference shielding

摘要

An ultrasonic water jet having first and second housing members. The first housing member includes an interior exponentially shaped duct and a plurality of water inlets equiangularly displaced and circumferentially disposed about the central axis of the exponentially shaped duct for cleansing a face of the quarter wave matching plate which is bonded to a ceramic disk transducer which forms part of a hermetically sealed assembly. This transducer assembly is both water tight and electromagnetically shielded.
