👉 The driving fluid, often referred to as the working fluid, is the primary medium through which energy and materials are transported within a fluid power system. Typically, it's a liquid (such as oil or water) or a gas (like air) that is pressurized and directed through components like pumps, valves, and actuators to perform mechanical work. This fluid enables the conversion of energy from a power source, such as an electric motor or internal combustion engine, into mechanical force, which can then be used to power machinery, vehicles, or other mechanical devices. The properties of the driving fluid, including viscosity, density, and thermal conductivity, are crucial for the efficiency and performance of the system.
