Internal support
The displacement units in a hydrostatic displacement machine (pistons or rigid vanes) are supported by a cam (eccentric) in an eccentric position on the shaft. The size of the stroke determines the le
Static parameters of continuously adjustable valves
The static behaviour of a continuously adjustable valve describes the connection between the input variable and the output variable of the valve for the stationary state after settling. This includes
Neutral position of the pump
Variable pump in position " Delivery flow zero". Often, the pressure hold position of the pump, i.e. the position in which the pump covers the leakage losses incurred, is – incorrectly – labelled the
Load collective
Typical demand made of the drive during a working cycle . .
5-way valve
Directional valve with a second tank connection. This design was very popular for a long time, as on the one hand it was possible to place different loads on the two connections and on the other hand
Tolerance of unit step response
Difference between the largest and smallest permissible deviations of the from the limit (DIN 19 226 Part 2).
Accumulator pressure on temperature change
The accumulator precharge pressure (p0-> p0h) changes with the ratio of the increased or decreased temperature T0h to the original temperature T0. Calculate the accumulator pressure on temperature cha
Pulse width modulation
Collective term for all processes used to convert an analogue signal into digital signals , which use pulses as information carriers. This is done by changing (modulating) one or more of the signal. A
