Hydraulic Regulator
a regulator in which the pressure of a liquid fed from a constant supply acts on a regulating mechanism. Hydraulic regulators are usually designed to function according to the integral, proportional, or integral-proportional laws of regulation. Membranes, bellows, and other devices that transform the value being measured into a proportional force (less frequently, into a proportional movement) serve as the receiving (sensing) elements of hydraulic regulators. Hydraulic actuating mechanisms based on double-action hydraulic cylinders are most often used in hydraulic regulators, but relatively simple hydraulic regulators may utilize single-action membrane actuating mechanisms. A hydraulic regulator’s advantages include dependability, simplicity of design and maintenance, and small size and weight. Its main shortcoming is the need for constant monitoring of leaks of the operating liquid. Want to thank TFD for its existence?
