Abstract
A constriction device for a steam trap of a radiator, which may replace prior art thermostatic elements and valves in the steam trap body. The device includes a nozzle body that replaces the valve, and a venturi-like constantly open passage extends through the body. The passage has a turbulence producing inlet and a turbulence reducing outlet and a connecting throat. A filter screen is carried by the nozzle body to prevent particles from being carried into the passage.
