The purpose of this system may be to control where fluid flows (as in a network of tubes of coolant in a thermodynamic system) or to control fluid pressure (as in hydraulic amplifiers). For example, hydraulic machinery uses hydraulic circuits (in which hydraulic fluid is pushed, under pressure, through hydraulic pumps, pipes, tubes, hoses ...
The Galion Iron Works Company of Galion, Ohio, was founded by David Charles Boyd and his three brothers in 1907.In its early years, the Galion produced a wide range of road-building and other construction equipment, such as drag scrapers, plows, wagons, stone unloaders, rock crushers, and a variety of other "experimental machines".

Through corporate diversity into hydraulic construction equipment, the growing popularity and productivity of this type of hydraulic machinery yielded strong business growth for the Warner & Swasey company of Cleveland, Ohio during the years of 1946 through 1977. Badger Machine was sold to Alvis International Group in 1978.
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. [1] Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft ...
A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
