The specialist fluid technology committee at the VDMA has also produced [...] technology lies with the specialist fluid technology department at the Normenausschuss Maschinenbau (Standards Committee Mechanical Engineering – NAM). They work on all DIN, ISO and DIN ISO standards. In addition

calculated from the flow rate Q, the effective area of the cylinder A (extend speed - piston area , retract speed - annulus area ) and the number of cylinders ic. Calculate the cylinder velocity directly

Method for making the functional - and often complex - relationships involved in the operation of hydraulic devices visible by means of schematics (circuit diagrams) in which the various processes are

displacement unit perform several strokes (between four and eight or so) per revolution. These — with one exception — are radial piston units fitted with a stroke ring designed accordingly ( Figure M 8 ).

continuously adjustable valves: Barometric feedback – the simplest form of feedback. Mechanical feedback – primarily used in servo valves. Electric feedback – primarily used in proportional valves. The type [...] type of feedback system has a very strong impact on the dynamic behaviour of the internal ( Figure R 37 ).

with a delay ( Figure R 10 ), resulting in a general voltage increase. The charging speed – and therefore the gradient of the ramp – may be influenced by a changing resistance (R).

Hose that is designed such that - unlike a normal hose - it expands a relatively large amount under pressure (Figure D 8) . In this way it is particularly suitable for removing pressure peaks and pressure

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 example, using a

filters – regardless of the size of the pump flow rate – must be selected according to the largest flow rate present. This occurs when refluxing a cylinder . with A K = piston surface area, c R = return

Determining the measured value of a physical variable — the measured variable — by means of an indirect or direct comparison with a known reference variable. Measuring requires a master reference element
