Abstract
Abstract 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 ceramic disk transducer clamped between the first housing member and an O-ring seated in the second housing member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
An ultrasonic water jet comprising in combination: a first non electrically conductive housing section having an interior exponentially shaped duct; a second electrically conductive housing section having a circular slot; a non electrically conductive O-ring disposed in said circular slot; a plurality of equiangularly displaced slots in said first non electrically conductive housing section circumferentially disposed about the central axis of said exponentially shaped duct; and, a disk shaped piezo electric transducer disposed along said central axis between said slots and said non electrically conductive O-ring.
Claim 2
Dependent Claim
86 words
An ultrasonic water jet comprising in combination: a first non electrically conductive housing section having an interior exponentially shaped duct; a second electrically conductive housing section having a circular slot; a non electrically conductive O-ring disposed in said circular slot; a plurality of equiangularly displaced slots in said first non electrically conductive housing section circumferentially disposed about the central axis of said exponentially shaped duct; and, a disk shaped piezo electric transducer disposed along said central axis between said slots and said non electrically conductive O-ring.
Claim 3
Dependent Claim
35 words
An ultrasonic water jet according to claim 1 wherein said first non electrically conductive housing section includes nozzle portion having an end portion including a planar surface disposed at right angles to said central axis.
Claim 4
Dependent Claim
26 words
An ultrasonic water jet according to claim 2 wherein said end portion has an inner water outlet having a diameter of between 5/8 and 1/2 inch.
Claim 5
Dependent Claim
46 words
An ultrasonic water jet according to claim 2 wherein said first non electrically conductive housing section has a ball shaped end portion formed at the end thereof opposite said nozzle portion thereby enabling ball and socket mounting of said water jet to facilitate scanning of parts.
Claim 6
Dependent Claim
23 words
An ultrasonic water jet according to claim 1 wherein said non electrically conductive housing section comprises molded plastic having a polished internal surface.
Claim 7
Dependent Claim
102 words
In combination in an ultrasonic water jet: a first non electrically conductive housing section having an interior exponentially shaped duct; a second electrically conductive housing section; a disk shaped piezo electric transducer concentrically disposed about the central axis of said exponentially shaped duct; a plurality of water inlets disposed about the central axis of said exponentially shaped duct, said water inlets arranged to direct a corresponding plurality of streams of water against a major surface area of said disk shaped piezo electric transducer thereby reducing water swirling and bubble formation at said major surface area of said disk shaped piezo electric transducer.
Claim 8
Dependent Claim
102 words
In combination in an ultrasonic water jet: a first non electrically conductive housing section having an interior exponentially shaped duct; a second electrically conductive housing section; a disk shaped piezo electric transducer concentrically disposed about the central axis of said exponentially shaped duct; a plurality of water inlets disposed about the central axis of said exponentially shaped duct, said water inlets arranged to direct a corresponding plurality of streams of water against a major surface area of said disk shaped piezo electric transducer thereby reducing water swirling and bubble formation at said major surface area of said disk shaped piezo electric transducer.
