  1. Throttle

    A throttle is the mechanism by which the flow of a fluid is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases, but usually decreased. The term throttle has come to refer, informally and incorrectly, to any mechanism by which the power or speed of an engine is regulated. What is often termed a throttle is more correctly called a thrust lever. For a steam engine, the steam valve that sets the engine speed/power is often known as a regulator.
