Devices and functions involved in with the task of performing the spatial coordination and synchronisation of the individual sub-functions in a process. The sequence of all sub-functions is to be stor

Filtering of the oil sucked up by the hydraulic pump . Theoretically ideal, as then the pump is also used optimally. In reality, however, as the dirt absorbing capacity drops, there is a risk of cavit

Fluid where the shear stress is proportional to the velocity gradient dv/ds: The proportionality factor η is referred to as the dynamic viscosity . Mineral oil is a Newtonian fluid, whereas lubricatin

Also referred to as multi-loop controllers, these are controllers where, in addition to the actual controlled variable such as the position, one or more other variables such as the velocity and/or acc

The part of a filter that undertakes the actual filtering action. Filter elements are generally designed so they can be replaced easily and are disposed of after use (exception: metal filters). The ti

Follow up control in which the reference variable is specified according to a time schedule (also called the schedule controller) (DIN 19 226 Part 5).

A hydrostatic transmission with secondary adjustment works with an impressed flow ( constant current network ) and has a constant pump and a variable motor, which performs the torque setting itself. T

Slim, cylindrical measuring device for simultaneous recording of static pressure perpendicular to the direction of the flow and total pressure along the direction of the flow. The pitot-static tube is

Amplification in the and therefore the product of the amplification factors (proportional coefficients) associated with the individual elements (, controlled subsystem , measuring device) in the open

The total efficiency of a hydraulic device or system is always given by the product of the volumetric and the hydromechanical efficiency (Figure G 7) :
