Closed circuit ; Fluid power ; Hydraulic equipment ; Hydraulics ; Hydrostatic transmission ; Open circuit. Hydraulic circuits transmit and control power from a mechanical input to a mechanical output by means of liquids, mostly oils. Power is transmitted hydrostatically, where high pressures make static forces dominate over dynamic forces, and energy is transmitted mostly through static pressure at low flow velocities. Circuits are composed of a number of hydrostatic components which are connected to each other by means of piping, manifolds, or directly, to enable transmission and control of power or signals through liquids. Hydraulic circuits are used in industrial and mobile applications to transmit power from a prime mover to operate machine parts or vehicles. Stationary applications include tool machines like presses, injection molding, and wherever heavy parts need to be moved fast and precisely. Examples for outdoor applications are ship lock gates and

Below are some common illustrations of equipment located on fluids circuit diagrams, followed by descriptions of the most common elements. Later in this article series we will describe some simple hydraulic and pneumatic circuits composed of these circuit elements. Needle valves are used to throttle or shut-off flow of fluids. They usually will vary flow with pressure or viscosity change. Gauges are used to measure the oil pressure at a given point in the system.
The first edition of this book was intended to provide knowledge of hydraulic components, their operating characteristics and available circuit arrangements to assist in the design of hydraulic systems for a range of applications. For some circuits it is important to predict the dynamic performance of the overall system particularly where closed loop control is being employed. For this purpose and to provide a general understanding of how parameters vary transiently analytical methods are developed that provide techniques for studying the dynamics of systems.
А вы тем временем погибаете. - Он посмотрел на экран. - Осталось девять минут. Сьюзан, не слушая его, повернулась к Соши. - Сколько там этих сироток? - спросила. Соши развела руками.
Нуматака введет этот алгоритм в чипы VSLI со специальным покрытием и выбросит их на массовый рынок, где их будут покупать производители компьютеров, правительства, промышленные компания. А может быть, он даже запустит их на черный рынок… рынок международного терроризма. Нуматака улыбнулся.
