adjustable valves requires special measures on the control edges . In servo valves straight control edges with high precision are used (zero cut, (Figure F 7) ) that provide a linear opening stroke characteristic [...] However, a progressive characteristic is better for fine control of flow, as is achieved approximately with a chamfered edge. Triangular notches are even better; these provide a significantly better resolution

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

The operational amplifier is a DC amplifier with a large negative gain factor, very high input resistance and very high output resistance. The operational amplifier always operates on the principle of [...] connecting various impedances results in a different kind of transfer function, including those associated with an amplifier, totaliser, differentiator, ramp generator, limiter and the like. Operational amplifiers

linking, saving and amplifying electrical signals , ease of compliance with priorities as well as the design of redundant circuits with hydraulic systems. The alternative is: mechanical-hydraulic or pneu [...] Collective term for all hydraulic feedback controls with electrical (electronic) signal processing. As the to the hydraulics - the servo valves and proportional valves - has already been in use for some [...] term "electro-hydraulic control technology" is to be preferred over the term "servo technology", as with the latter the reference to the hydraulic application is missing. Electro-hydraulic control technology

variables, often with a constant third being used as the parameter. Example: In Figure D79, the flow rate Q is applied to a control edge in relation to the pressure difference p, with the opening cross [...] adjustable valves with more than one input signal (flow rate, pressure), performance maps will be specified. The parameters kept constant in this regard need to be applied to the curve with their respective

(MH system, b ) there are no tilting forces on the pistons that together with the cylinder drum remain free of torque. Along with these two designs the swash plate pump is also an axial piston machine. [...] Pump (motor) with several pistons (as rule 7 to 11) that are arranged parallel to the drive shaft. The pistons are actuated by a swash plate or a drive flange ( inclined axis ). These two designs differ [...] y in the resolution of the piston forces and the consideration of the change in torque over time. With the swash plate (MZ system ( Figure A 30 a )) the resultant piston force generates a torque at the

Pressure difference as a function of the flow rate , e.g. for the reversed flow rate direction on valves with bypassing check valve:

the control piston (control spool) of a valve. The expression is also used for directional valves with valve control spools ().

Non-continuous controller with two switching positions. The output signal can only take on 2 different values (neglecting the switching processes). Multi-position controller

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