Control memory
Functional unit within a control , which stores programs (program memory) or other data (data memory) in a digital representation (EDIN 19 226 T 5).
Accumulator drive
Variation of central hydraulic oil supply (system with impressed pressure), in which a hydraulic accumulator performs the task of providing energy at power peaks. This can be used to select the flow r
Voltage tolerance for solenoid valves
Permitted voltage deviation, at which the function must still be guaranteed given the maximum valve performance and at which the electrical actuation (under given test conditions) is still resilient u
Stress relaxation
States the reduction of the tension on an elastomer (seal) at a constant deformation and constant temperature and is therefore an important measure of the residual elasticity of a seal under pressure.
Gap bridging
Ability of elastomer seals to bridge a gap with their spine, without being squeezed in ( gap extrusion ). The gap bridging depends on the type and hardness of the material.
Gap extrusion
Property of an elastomer seal to become squeezed behind the seal under the influence of pressure in the sliding gap, causing damage to the seal ( Figure S 65 ). Remedy: Another material back ring made
Gap seals
Non-contact seals , which are characterised by a final distance between sealing surfaces, in which the working medium (against which it is to be sealed) is located. The geometry of the sealing gap (si
Special cylinder
Hydraulic cylinders which have been designed for defined applications, where neither standard cylinders nor series-production cylinders can be used. This includes, for example, press cylinders or cyli
Secondary measures (in the case of sound)
Sum of all measures, which the system designer must take for a given pump (motor) to produce a quiet system (see noise creation in hydraulic systems). Specifically, this means: measures, which can red
