regulator

1. One that regulates, as:
   1. The mechanism in a watch by which its speed is governed.
   2. A highly accurate clock used as a standard for timing other clocks.
   3. A device used to maintain uniform speed in a machine; a governor.
   4. A device used to control the flow of gases, liquids, or electric current.
2. One, such as the member of a governmental regulatory agency, that ensures compliance with laws, regulations, and established rules: banking regulators; price regulators.
3. A substance that affects the amount of product or the progress of a biochemical reaction or process: a regulator of embryogenesis.
4. See regulator gene.

A control device designed to maintain the value of some quantity substantially constant. The value to be maintained can usually be established at any value within the range of the regulator by making an appropriate setting. A regulated system is a feedback control system employing a regulator to maintain some quantity of the system at a constant value. See also Control systems.

The mechanical part of a gas delivery system that controls gas pressure that allows a manageable flow of drug vapor to escape.

n. see North Carolina Regulators.

See the Introduction, Abbreviations and Pronunciation for further details.

In a gas supply system, a device for controlling and maintaining a uniform gas supply pressure.

Regulators were vigilantes. The term was used by the 5,000 to 6,000 Regulators in the Carolinas between 1767 and 1771, adopted from an earlier, short-lived London police auxiliary. Most American regulators sought to protect their communities from outlaws and tyrannical public officials. Some groups employed summary execution; more employed flogging and exile. Regulators were active in almost every state, peaking recurrently from the 1790s to the late 1850s. After 1865, a few Regulator groups flourished, mainly in Missouri, Kentucky, Indiana, and Florida. Some interfered with freedmen, but most concentrated on crime deterrence and punishment. Similar organizations included Slickers, law and order leagues, citizens' committees, vigilance committees, and committees of safety.
