restrictors
Devices that constrain
Restrictors are devices or mechanisms that limit flow, movement, or capacity.
An engine restrictor reduces airflow to limit horsepower in racing.
A water flow restrictor caps how much water passes through a showerhead.
The term applies broadly to anything designed to impose limits: Safety restrictors prevent the window from opening more than a few inches.
