Stuffing box
Seal for shafts and spindles (including against high pressures), that uses a tubular-shaped textile sealing material, which is under axial pressure, which, like the radial sealing tension created by t
Pressure compensator
Expression frequently used for a pressure controller for variable pumps.
Sinus response
Change of the output variable over time in the case of a sinus function as an input variable in a steady state ( Figure S 62 ) (DIN 19 226 T 2).
Fluid power standards
Responsibility for working on and drafting standards for fluid technology lies with the specialist fluid technology department at the Normenausschuss Maschinenbau (Standards Committee Mechanical Engin
Modular control
Control system with a modular structure in terms of hardware and software, making it more easily adaptable to variable conditions. Opposite: control with a rigid structure.
Multiple pump
Pump block consisting of several individual pumps with a shared drive shaft. This is achieved by either arranging things axially in a row (where the shaft for the first pump has to transfer all the po
Sound in air
Sounds in air or gases are due to small changes in pressure in terms of time and space ( pressure waves ) caused by disruptions in pressure and are superimposed on the static pressure. They are propag
Flush valve
Hydraulically actuated directional valve that ensures in a closed circuit that the oil brought into the circuit by the Flushing pump is once again flushed out on the respective low-pressure side.
Pressure/flow rate diagram
On continuously adjustable pressure valves : dependency of the pressure on the flow rate with the input signal as a parameter (E DIN 24 311) (Figure D 81) .
