Metallic seals
Used as flat and round seals . In order to provide a tight seal, they must undergo plastic deformation, which enables them to fill up any surface roughness . This is why they can only provide a tight
Hydrostatics
Branch of hydraulics . Concerned with the generation and transmission of energy and signals via the static pressure associated with a fluid. This is why, compared with hydrokinetics , the pressure ran
Pressure feedback
Feedback of the pressure for the purpose of stabilising a . In general this feedback operates as a secondary loop.
Releasable check valve
Check valve that can also be opened against the locking direction if required. This action occurs via a control piston (K 2) that is dimensioned so that it can open the valve cone against the system p
Automatic sealing
To make elastic seals actually seal they are deformed on installation such that radial forces, the so-called preload , are produced that make it impossible for the hydraulic fluid to flow around the s
Disturbance range
Range within which the disturbance variable can lie, without jeopardising the functionality of the control or (DIN 19 226).
Flow coefficient αD
The flow coefficient α is a proportionality factor for the calculation of the flow rate through flow resistances, for example the following applies for orifice-shaped resistances with A = geometricall
Bottom end of a cylinder
The closed end of a cylinder . It can house the rear end position damping and/ or the mounting of the cylinder.
Pilot-controlled valves
Valves with a large nominal width (generally greater than the nominal size 16 or sometimes at nominal size 10 or nominal size 6) and therefore with large actuation forces are pilot-controlled by a sma
