Control springs
Springs, in which the proportional relationship between the deformation path and the force produced is used for a force comparison in hydraulic controls. A balance is sought between a compressive forc
Neutral position of the pump
Variable pump in position " Delivery flow zero". Often, the pressure hold position of the pump, i.e. the position in which the pump covers the leakage losses incurred, is – incorrectly – labelled the
Pump drive
Drive system, in which the flow rate for all movements is provided directly from pumps (without a storage facility). If different speeds are required, constant pumps are used in throttle control and v
Pump drive capacity
Power at the pump drive shaft at a given point in time or under given load conditions.
Pulse width modulation
Collective term for all processes used to convert an analogue signal into digital signals , which use pulses as information carriers. This is done by changing (modulating) one or more of the signal. A
Pulse duration modulation (pulse width modulation)
Illustration of an analogue signal profile using the relative duration of a rectangular pulse within a specified cycle (period), which must become shorter as the process becomes more dynamic ( Figure
Pulse code modulation
Process for converting analogue signals to digital signals . Sampling will convert a signal that is continuous over time into a series of impulses. The transfer does not take the form of impulses of d
