The manufacturer's instructions, in particular for the ratios of the pressures p0, p1 and p2 to each other, must be observed. For the pressures above 200 bar, the real gas behavior deviates s [...] influences the usable volume . For slow (iothermal) pressure change, the value κ=1, for fast (adiabatic) pressure change, the value κ=1.4. Calculate the storage volume directly and easily in our hydraulic calculator

switchover is very smooth, as - unlike the valve control, which controls the full delivery flow - the flow rate is also zero at the moment in which the direction of the movement is changed. The same applies to [...] rotating direction ( Figure R 27 ). Reversing pumps are used in closed circuits, where they allow the rotating direction of the motor to be changed without valve control. At the same time, the switchover

Valve assembly system in hydraulics whereby a mounting area for valves — to which the pipe is screwed from behind — is attached to the drive unit, while the valves are mounted from the front so they are [...] is how the pressure and delivery flow pulsation in the pressure fluid cause higher noise emissions at the wall, not to mention the large amount of space taken up, the extensive pipework and the many areas

Fluid valve with binary behaviour, i.e. it moves from one switching position to another (e.g. Open – Closed) without adopting an intermediate position.

droplets. Micro-emulsions are associated with a far higher degree of dispersion — even reaching the colloid dispersion range — than commercially available macro-emulsions. Micro-emulsions may only be used

the control of hydraulic systems is concerned, a distinction must be made — since the term " control " is rather a general one — between control in the signal range and control in the power section. The

The pump is then switched to circulation,
