It just happens that they build the restrictor into the thermostat.
The point was and still is, Thermostats are used to regulate flow.

Here from the Wiki:

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by switching heating or cooling devices on or off or regulating the flow of a heat transfer fluid as needed to maintain the correct temperature.


Can we get back on topic now please?
