Beta value (β value)
Measure for the effectiveness of a filter. The value is a ratio that is defined by the number of particles before and after passing through the filter with a specific pressure drop (Figure B 13) : The
Reservoir expansion capacity
Gas (air) volume above the maximum fluid level in a vessel that is intended to absorb the expansion in the volume as the temperature of the fluid changes (CETOP RP 100).
Automatic control
Control of a vehicle with hydrostatic drive by operating the pump as a function of the accelerator pedal for the combustion engine and therefore its rotation speed. Pulling away is therefore gentle an
Starting position; basic position
Position of the moving parts in a device at which the intended switching program starts under the action of the actuating forces. It is achieved via the starting prerequisites (CETOP RP 100).
Serial
One after another, bit by bit. For example, a transfer is serial if the information is passed on one after another on the same line. Opposite: Parallel
Oscillations
Exchanges between different energy forms, which take place more or less without hindrance. In hydrostatics, these are the kinetic energy of moved masses and the potential energy of the pressured liqui
Frictional pressure
The differential pressure required to move a piston without an external load – i.e. to overcome the friction Differential pressure under defined conditions in the cylinder chamber.
Computer controls
Collective term for machine controls, which work with computers, such as CNC , DNC, PLC, etc..
Quantisation
Conversion of an analogue variable into a discrete representation. In general, therefore, this means quantising an amplitude, with the amplitude area divided into smaller subsections. The process is k
Primary pressure
Pressure in the main circuit of a system (DIN 24 312).
