Constant flow system
pumps (in a closed circuit, with a variable pump ) and can only operate one load at a time ( Figure K 30 ). If there is more than one load in a system, these must be connected in such a way that they can [...] after the other (e.g. series circuit ), or flow valves or flow dividers will have to be used.

Piston rings for sealing
, it has the advantage of showing very little wear and also being able to slide over bores (Figure K 18) . On the negative side, the piston ring's lack of suppleness as a contact seal means it has practically [...] however, if the impact occurs at an angle or in stages and by installing more than one ring.

Cascaded (multi loop) control system
position, one or more other variables such as the velocity and/or acceleration are also fed back (Figure K 2) . The decisive factor is the type of feedback involved. With the cascaded (multi loop) control system [...] cascaded (multi loop) control systems have not fared very well compared with state controllers .

Compact seal
The installation spaces for the piston and rod are set out in the DIN 7425 standard (Figure K 22) . Figure K 22: Two-part compact seals fit inside uniform installation spaces in accordance with DIN/ISO
Heat balance in hydraulic systems
oil container is primarily involved in this. Depending on the ventilation of the surface A, k = 5.8–11.6 W/m2K can be used if the temperature difference is at least 25°C. This creates a heat balance. If
Constant pressure system
pressure systems generally experience greater losses than systems where the pressure changes (Figure K 29) , although they offer the advantage that loads connected in parallel can also be operated with one [...] control technology, they are also essential for the high level of dynamic performance required.

Single or separate drive for machines
its movements overlap with others, has a dedicated pump with a size based on the highest load speed v k required (Figure E 13) . This means that high speeds require correspondingly high power: Here the duration [...] output (speed) is often not relevant for the size of the motor. On the usage of constant pumps with Q k it is a disadvantage that the installed power P max is only required at one operating point (at p max
Delay element
parallel-connected transfer elements with additional time delays. They are marked Tk, where the index k states the order of the delay (according to Din 19 226 Part 2).
