(Figure A 24) . Example: Sealing test specimens in pipe test presses or shaft sealing in conjunction with sliding ring seals .

used infrequently these days. Instead the easier to use but also more expensive variable pump is used with a delivery flow that must be equal to ΣQ n.

Valve with the task of switching circulating the pump flow rate back to the container without pressure if it is not needed. In order to keep power losses low in doing so, this takes place on the shortest

Gearboxes with an external power split comprise a mechanical summation gearbox (planetary gearbox) in the direct flow of power and an adjustable gearbox (hydrostatic transmission) in the parallel circuit

controlling device with memory is present if the device remains in the most recently assumed position as long as the control device does not issue an output signal. Final controlling devices with adhesion behaviour [...] Combination of the actuator and the it mechanically actuates ( Figure S 82 ) (DIN 19 226). Starting with an from the control device, the final controlling device intervenes in a mass flow and/or an energy

particles in the pressure fluid. These impurities may be caused by various things: debris associated with metallic and non-metallic particles produced by wear such as chips from bearing or pump materials [...] example, smaller particle sizes tend to be more common. This distribution is divided, in accordance with various processes (ISO 4066, NAS 1638, SAE-ASTM-AIM), into contamination classes or cleanliness grades [...] metal surfaces or seals and cause scoring to occur there. Much depends on how their size compares with the respective gap width: Particles which are much smaller than the gap to which they have gravitated

in which the swash plate and the control disc are firmly connected to the drive shaft and rotate with it, while the cylinder block, which is firmly connected to the housing, does not rotate ( Figure T

the side opposite the pressure to be measured is hermetically sealed as a reference chamber (e.g. with a glass plate or glass bushing). The reference pressure defined in this manner in the chamber can

are allowed to be operated. The calculated pressure corresponds to the rated value in accordance with DIN 40 200 (DIN 24 312).

from an electro-mechanical into hydraulic signals. This is mainly achieved by throttling an oil flow with controllable mechanical resistors or transforming the kinetic energy of an oil flow into hydrostatic
