Abstract
A beverage maker, such as a pump espresso machine, comprises a noise attenuator reducing pump noise. The noise attenuator has a housing with an inlet chamber receiving inlet flow from an inlet port, the inlet chamber having compliant walls permitting volumetric expansion. An outlet chamber in the noise attenuator housing has an outlet port and spheroidal walls. A flow-restrictor is disposed between the inlet and outlet chambers. An elastomeric insert in the housing forms the inlet chamber and at least part of the outlet chamber.
