Electrohydraulic

Part of speech: adjective

Definitions

1. This term denotes systems that integrate electrical components with hydraulic functions to enable fluid movement through electronic control mechanisms
2. It refers to the technology that merges electrical engineering with hydraulic principles to control and manipulate fluid power
3. This expression describes a combination of electrical systems and hydraulic dynamics that facilitates the control of fluid through electronically managed processes

Etymology: Hydraulics, the use of pressurised liquid to transmit force, goes back to the Greek "hydraulis," a water organ in which air pressure driven by falling water pushed air through pipes. "Electro-" comes from "elektron," the Greek word for amber, whose rubbing produced static charge and gave English the whole electrical vocabulary. Joined together, the two halves describe machinery in which an electric signal, rather than a human hand, sets fluid pressure to work. The compound is a plain, modern formation: "electro-" is attached to "hydraulic," and the result names systems such as valves, brakes or clutches that are operated by electrical control while the actual force is still delivered by oil or another liquid. Because the combining form "electro-" is productive, it has been fixed to many older English words in the same way, which makes this one easy to read at a glance.
