directional valves with a spool this situation can result in undesirable incorrect switching. In addition, there is of course also the behaviour of technical fluids that behave in accordance with laws: The viscosity [...] . Every force acting on a stationary fluid generates a pressure that propagates in all directions with the same magnitude. This the basic law of hydrostatics . All force and pressure processes in fluids

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 [...] Relatively long switching times, Relatively low attraction force, As DC solenoids primarily operate with 24 V, a transformer and rectifier are required. It is possible to accelerate the increase in current

which (may) occur when positioning hydraulic drives. They consist of; the Δs N, errors associated with hysteresis and the reversal error for the continuously adjustable valve (between 0.1% and 2 to 3%)

signal (signal value) read off at the output of a measuring device and specified in units associated with the variable to be measured is known as the measured value . Depending on the position of the measured

Special pressure switch valve with the task of switching the constant pump, which charges a hydraulic accumulator , to pressure-free circulation as soon as it reaches its charging pressure and to switch

term pressure filter can also have a broader scope (as per EDIN 24 550). Then it covers every filter with the exception of the suction filter .

50 kW axial piston motor would be around 0.2 s (the run up time constant To for an electric motor with the same power would be over 3 s).

"apparent" leads to errors, as the word "apparent" is often left out, resulting in an association with the "real" dirt holding capacity, but the two are not connected.

flow resistance. Throttle is therefore the generic term for orifice and nozzle . Flow resistances with a largely linear dependence of the flow rate on the pressure difference ( capillary tube ) (Figure

cylinder , hydraulic motor ). If the setpoint changes, the positions of both valve elements will change with respect to each other until the difference to the actual value is zero again ( Figure N 1 ).
