reduce the speed of a piston before the end of its stroke. The damping can be mechanical or using a fluid; a choice can be made between fixed or adjustable ( Damping of cylinder motion ).

hardness. However, it is also affected by the temperature and the degree of exposure to the hydraulic fluid (swelling or shrinkage).

Device for removing undissolved air (gas) that may be carried in the hydraulic fluid in a hydraulic system . The valve must be fitted at the highest point in the system and can trigger automatically or

The self-tuning of controllers is intended to accelerate difficult and arduous initial settings of fluid technological regulations and thereby reduce a significant disadvantage compared with electrical

Flow rate , which builds up beneath a seal or guide ring as the fluid sticks on the moved metal surface by adhesion. The drag flow is responsible for the drag flow pressure , but also for leaks in intact

Line to feed the hydraulic fluid back to the container after the energy has been transferred. As with the Return line filter it must be designed according to the largest flow rate and not according to

The column of fluid in pipes is elastic and affected by both weight and friction. These characteristics are described in terms of the pipe capacity , the pipe inductance and the flow resistance (effective [...] (effective resistance). The column of fluid represents a homogeneous oscillating system as opposed to a discrete mechanical one. In a system of this kind, variable pressure and flow rate are dependent on both

Cylinder designed to be used with hydraulic fluids at generally higher pressures (of around 100 bar and above). Given the relatively low compressibility of the fluid and the low weight of a piston, hydraulic [...] Hydraulic cylinder with piston : The mechanical force is generated by the action of the hydraulic fluid on a piston. With this approach, a single cylinder is able to apply forces ranging from just a few

Hydraulic feedback : which uses a fluid signal, normally the pressure. Electric feedback : from electric signals, which are generally taken from a mechanical (fluid) variable using appropriate measuring [...] characteristic used to distinguish between feedbacks is the physical variable that is to be fed back. In fluid technology, this is primarily the location (path), force (pressure), velocity, acceleration, amongst

For the control movements of a valve pressure fluid is drawn from another (mostly control) circuit (external pilot control). The external pilot control has, compared to the internal pilot control, the
