Fluctuations of the flow rate of hydrostatic displacement machines resulting from the final number of displacement units and their sinusoidal working patterns ( Table U 3 ). It is expressed in the for

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

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

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

Electromagnet operated with DC. The DC solenoid only reaches its nominal current some time after switching on. For this reason the force initially increases more slowly, and it therefore switches more

Some of the oil film stuck to the piston shaft at the outlet of a cylinder is scraped off when the piston is inserted (results in leakage even in the case of an intact seal), while the other part is f

Pressure transducer based on the piezoresistive effect whereby pressure causes an elastic semiconductor structure to change, which in turn changes the values for resistances connected as a Wheatstone

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 so

Increase in the input signal that is necessary to cause a change in the power output by the (continuously adjustable) valve at a specific signal level, expressed in % of the input signal. The resoluti

Design for controls predominantly found in mobile hydraulics where more than two functions need to be controlled. Banked valves assemblies are mainly controlled manually and are manufactured as a cast
