Servo technology
In general : Summary of all processes that convert a weak input signal into a greatly amplified, proportional (power amplification). In fluid technology : Servo technology stands for an area that uses
Proportional valves
Continuously adjustable pressure , flow and directional valves which convert an adjustable input signal into a proportional hydraulic or pneumatic output signal and are generally actuated by a proport
Leakage compensation
Systems featuring leakage compensation ensure the pressure within individual devices does not drop — despite a leakage — by constantly compensating for any oil leaking out. This is achieved, for examp
Jet pipe amplifier
Hydro-mechanical converter (amplifier) system for servo valves , which is based on the conversion of kinetic energy to static energy. A jet pipe, which can be actuated by an electro-mechanical convert
Pipe capacity
Hydraulic capacity is a measure of the volume accommodated based on the pressure increase required. It is a function of the compressibility of the fluid. The compressibility of the oil in a pipe is in
Internal feedback control
that within a device or a closed system contain, e.g. a continuously adjustable valve or a linear amplifier , mostly a closed circuit position control system that improves the accuracy and reproducibi
Elastic materials
Most important material group for seals . Due to their elastic properties they can change shape on installation, adapt to deviations in the geometric shape of the surface to be sealed and make possibl
Amplitude response
The amplitude response is the magnitude |F (jω)|. The two lines represent in mathematics the magnitude of the frequency response as a function of the circular frequency. Graphically the magnitude of t
Auxiliary variables
All variables required in valves to convert the input signal into an . They are mainly used for the purpose of power gain (amplification) (DIN 24 311).
