摘要

The espresso or coffee pad machine has a brewing chamber fitted with an outlet nozzle (40) made up of an upstream section (90) and a downstream section (92). The cross-section of the downstream section is not less than that of the upstream section. An independent claim is included for nozzle plates for use as the outlet from the machine.
