Fluidic circuit with attached cover and method

A method of making a fluidic device comprising molding

• (a) a fluidic device silhouette in a surface of a first member,
• (b) a closure seal plate as a second member,
• (c) and a housing having a space for receiving a juxtaposed said first and second members, and
• forcing said Juxtaposed first and second members into said space for receiving while preventing any sliding between said first and second members as said first and second members are forced into said space for receiving:
• and
• wherein said first and second members are formed in one molding with a hinge therebetween and including the step of folding said first and second members on said hinge into said juxtaposed relation.

A method of making a fluidic oscillator comprising molding

• (a) a fluidic oscillator silhouette in a surface of a first member,
• (b) a closure seal plate as a second member,
• (c) and a housing having a space for receiving a juxtaposed first and second members, and
• forcing said juxtaposed first and second members into said space for receiving while preventing any sliding between said first and second members as said first and second members are forced into said space for receiving.

A fluidic device comprising:

• a first molded portion including a first part having a fluidic device circuit silhouette formed in one surface, said silhouette having an interaction chamber with upstream and downstream ends, a power nozzle at said upstream end adapted to receive a liquid under pressure and an outlet to ambient at said downstream end,
• a second molded portion comprising a closure seal plate;
• and
• a third molded portion having a recess adapted to forcibly receive said first and second molded parts with said closure seal plate engaging said fluidic device circuit silhouette.

A fluidic oscillator comprising:

• a first molded portion comprising:
• (a) a first part having an oscillator circuit silhouette formed in one surface, said oscillator circuit silhouette having an oscillation chamber with upstream and downstream ends, a power nozzle at said upstream end adapted to receive a liquid under pressure and an outlet to ambient at said downstream end, and oscillation inducing means in said oscillation chamber;
• (b) a closure seal plate part;
• (c) hinge means hingedly connecting said first part and said closure seal plate part such that said closure seal plate can engage said oscillation silhouette;
• and
• a second molded portion having a recess adapted to forcibly receive said first portion with said closure seal plate engaging said oscillation silhouette.
