Vibration fatigue limit of a system
A system is able to handle oscillations –– i.e. oscillations may occur –– if a periodic exchange of energy takes place between two energy stores (spring-mass system, e.g. a hydrostatic transmission, i
PROM
Programmable Read Only Memory Semiconductor memory .
Nominal size
The details relating to the nominal size of devices used in fluid technology are key variables which do not refer to units or dimensions and do not have to be associated with any numerical variable fo

Electro-mechanical converter.
Residual contamination
Quantity of contamination in the hydraulic fluid after filtering . This is currently mainly measured and counted using automatic counting devices. The result is a profile of contamination in accordanc
Hydro-mechanical signal converter
Converts mechanical 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
Fluid power systems with main pipe
Within a larger system several loads (drive elements) are supplied by one drive power pack. The fluid power system with main pipe can combine such loads, which do not interact, because e.g. they come
Accumulator regulations
Accumulators, which are increasingly used in hydraulics in the form of hydraulic accumulators , are considered dangerous systems due to the high (gas pressures) that occur inside them and require spec
Methods of valve installation
There are four basic types of valve installation: Pipe installation in which the valves are "suspended" in the pipe. This type is rarely used in hydraulics these days. Manifold mounting in which the v
