CETOP
The European Committee for Oil Hydraulics and Pneumatics was founded in 1962. Over 700 businesses from 13 European countries are represented in CETOP by the national fluid technology associations. The
Control volume for valves
Geometric volume required for the actuation element of a device to function.
Pressure pulsation-induced oscillations
Oscillations that occur due to the pressure alteration in the pump from the suction phase to the pressure phase. Their fundamental frequency depends on the number of displacement units in the pump, wh
Memory capacity
Information on the maximum quantity of information held by the memory. For digital memories, the memory capacity is expressed in storage cells (bits) or addressable memory locations ( words , bytes).
Desired pressure
Pressure that is required at a specific point at a specific time(DIN 24 312).
Signal duration
Period of time, after which an reacts to a signal change at the corresponding input according to its function (DIN 19 237).
Hose assemblies
The part of a hose line , which enables it to be connected to devices. In addition, the (fixed) fitting must be connected to the (elastic) hose such that this inclusion still has a quadruple safety le
Sound pressure p
The compression pressure of the air, which overlays the atmospheric pressure when the sound waves spreads. It is measured as an effective pressure in N/m2, but is stated in Decibels (dB) as a noise le
