Phillips Machine in the Science Museum, London. The Phillips Machine, also known as the MONIAC (Monetary National Income Analogue Computer), Phillips Hydraulic Computer and the Financephalograph, is an analogue computer which uses fluidic logic to model the workings of an economy.
Executed example of a Heron's fountain in operation. Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [1] Heron studied the pressure of air and steam, described the first steam engine, and built toys that would spurt water, one of them known as Heron's ...
Devices placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move: three linear movements x, y, z (lateral, longitudinal, and vertical), and the three rotations (pitch, roll, and yaw). Stewart platforms are known by various other names.

ASME brochure. 149: 1990 Hydromatic Propeller Early example of propeller innovations, including variable-pitch control and feathering capability. 1938 Windsor Locks
Hydraulic fuses are in-line safety devices designed to automatically seal off a hydraulic line if pressure becomes too low, or safely vent fluid if pressure becomes too high. Auxiliary valves in complex hydraulic systems may have auxiliary valve blocks to handle various duties unseen to the operator, such as accumulator charging, cooling fan ...
The physical basis of fluidics is pneumatics and hydraulics, based on the theoretical foundation of fluid dynamics. The term fluidics is normally used when devices have no moving parts, so ordinary hydraulic components such as hydraulic cylinders and spool valves are not considered or referred to as fluidic devices.
The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
The conversion device was called pangmok, and was placed above the inflow vessel that measured the time, the first device of its kind in the world. [49] Thus, the Borugak water clock is the first hydro-mechanically engineered dual-time clock in the history of horology.
