Elements used to accommodate programs . There is a wide range of options available. These include printed circuit boards with fixed programs, sequencers or program switching mechanisms with reprogramm

For the control movements of a valve pressure fluid is drawn from another (mostly control) circuit (external pilot control). The external pilot control has, compared to the internal pilot control, the

High volume low-pressure pump (mostly gear pump) for obtaining a high rapid traverse speed. It is shut down as soon as the pressure set on its idle circulation valve is reached.

The usable volume ΔV of a hydraulic accumulator results from the nominal volume V0 of the accumulator, the precharge pressure p0 and the upper accumulator pressure p2 and lower accumulator pressure p1

Throttle with a constant cross section. Opposite: variable throttle .

Power drawn at the shaft of a hydraulic pump at a specific point in time or under specific load conditions. It differs from the hydraulic power by the sum of the pump losses ( volumetric efficiency, h

Dynamic switching capacity : States the pressure p and flow rate Q at which a directional valve can still be switched ( Figure S 16 ). This is particularly important in the case of directly controlled

Characteristic whereby the relationship between two variables is not sufficiently linear, i.e. it does not satisfy the superposition and amplification principle. The term covers non-linear characteris

The terms covers not only the hydrostatic drive associated with a load, but also more generally the chain of effects involving hydraulic pump control hydraulic motor ( cylinder ), including the associ

These include imperfections in the object measured, the measuring instrument and the measuring procedure . In addition, there can be external effects such as temperature, humidity, position, accelerat
