The Engineer's right in his description , but wrong with your device. Plain
and simple, if you have a Bell or Cone on top you have a Regulator or Limiting
Valve. Under the Bell or Cone is a Spring that fixes your flow-rate, opening
or closing automatically in response to water pressure fluctuations. This and
yours delivers a fairly constant outlet pressure.

While the word Reducer is correct for yours, because it's actually doing that
and the name is even interchangeable by some people. However, the proper usage
of the word Reducer usually applies to devices that don't have a spring and
are just designed with a static fixed flow-rate or low-flow. These rely on
supply pressures being mostly constant, therefore they do fluctuate whenever
the supply does.
