To remove particles of dirt that the pressure fluid is carrying with the aid of filtration of a wide range of types.

Ratio between the direction of the controlled hydraulic fluid flow and the direction of the electrical input flow for continuously adjustable valves.

Hydraulic speed control during which the hydraulic fluid flowing out of the actuator is throttled, e.g. by a flow valve in the return pipe.

Fluid valve with binary behaviour, i.e. it moves from one switching position to another (e.g. Open – Closed) without adopting an intermediate position.

Line which returns leaked fluid to the container. Its dimensions should ensure this is possible at all times with hardly any pressure — even at low temperatures.

rate that a pump delivers. The term delivery flow should as far as possible no longer be used in fluid technology, instead flow rate should be used.

In hydraulic fluid removal of the air carried and separated out. This must take place at the highest point with the aid of bleed screws or bleed valves.

Resistance which a fluid flowing inside pipes or similar bodies must overcome. It is higher for laminar flow than for turbulent flow: where A S = flow cross section.

Compressed air filters that can retain particles of dirt down to 0.01 μm. This includes fluid particles of this size (e.g. aerosols), and also bacteria and viruses.

mostly a rectangular cross-section that is fastened to the shaft and to which a flow of hydraulic fluid is applied.
