Gap between two chambers with different pressures. To prevent leakage either the gap must be designed such that no pressure flow can be produced ( gap seal ) or special elements are used, the seals. I

Size (possibly limit value) of the axial and/or radial load of the shaft of hydraulic pumps or hydraulic motors .

Circuit arrangement to prevent undesired actuations or to protect against overloading. The safety elements required for this, such as valves with a redundant design, electrical monitoring of switching

Valve combining several functions (e.g. flow + pressure or direction + flow + pressure). Example: flow control valve or continuously adjustable valves where the size of the flow or pressure is recorde

In general : Summarises the type and scope of the effect of disturbance variables and describes their influence on the system. Interference response of a controlled subsystem : Transfer function of th

alongside transporting hydraulic fluid to moved consumers ( cylinders , motors ), often have the task of damping pulsations and pressure surges . As the hoses also have to work even under high pressur

The proportion of hydraulic fluid within the total volume of a hydraulic accumulator that can be removed without causing any damage.

Hydraulic pump in which the pressure fluid is displaced by one or more pistons . Pistons may be arranged in a row or aligned radially or axially in relation to the drive shaft.

Piston rod seal as combination of a grooved ring seal with rounded sealing edge with a scraper (Figure D 11) . Often an angled metal ring is vulcanised into the seal to improve the seating of the ring

Sensor which converts measured variables for analysable signals with the help of an external energy source. With passive sensors, electrical such as resistance, capacitance and inductance are modified
