Transmission pressure
Pressure, which arises under the influence of a transmission ratio before the smaller area A 2. It is Ratio of piston areas α α greater than the pressure p 1 acting on the larger area A 1 by the ratio
Transport movement of a cylinder
The transport movement of a cylinder is characterised by the force/time curve and the position/time curve. Normally, the largest force to be applied by the cylinder occurs when the load is being accel
Velocity feedback loop
On closed loop position control systems an additional superimposed velocity feedback control circuit that is used particularly on drives with electrical servomotors. The velocity feedback loop does no
Supporting ring
Element which prevents the axial displacement of a seal in its installation nut. Supporting rings are made primarily of elastic materials and can be loose in the seal or can be vulcanised into the sea
Electro-hydraulics
Area of hydraulics in which the devices are controlled electrically (as a rule by means of solenoids, in some circumstances also by control motors). This statement includes in the signal area also ele
Control switch
Hand-operated switch, which activates, converts or deactivates a signal or an action path (DIN 19 226).
External support
The displacement units in a hydrostatic displacement machine (vane, piston) are supported on an outer raceway that at the same time defines the stroke of the displacement unit due to the eccentric mou
Static seal
Seal intended to seal a non-moving surface. Although the expression is often used, it is incorrect, as the seal is not "static", but only seals a non-moving surface.
Fatigue strength
Fluid devices and systems are always given a load from zero to the maximum, i.e. they are subject to a pulsating load. Therefore, either the fatigue strength under fluctuating stress or the fatigue li
Cutting ring fitting
. Cutting ring systems in accordance with DIN 2353, various forms of cutting rings are standardised in DIN 3861.
