Abstract

A fluid line includes a resonator having an inner part and a blow-molded outer part defining an inner surface. The inner and outer parts are fixedly connected. The inner part is an injection-molded part having first and second radial collars spaced axially apart from each other. The inner part defines a radial circumference with a plurality of orifices formed therein. The inner and outer parts are axially one within the other so that there is no throughflow of secondary air between the first and second radial collars and the inner surface of the outer part. The inner and outer parts have a common end whereat they are airtightly connected to each other. The inner part, the radial collars and the inner surface of the outer part conjointly define two resonant chambers operatively connected to fluid in the fluid line via the orifices.
