Biggest difference for the same when travelling across the full signal range (i.e. forwards and backwards). Hysteresis values are expressed as a percentage of the max. signal value (Figure H 31) . Wit

Collective term for pumps and motors which operate in accordance with the laws of hydrostatics (see also hydrostatic displacement machines).

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, hy

Switching system which makes it possible to operate a differential cylinder in a network with impressed pressure ( constant pressure network ) without experiencing pressure losses due to throttles, an

Hydrostatic transmission for a stepless vehicle drive which generally operates in a closed circuit with primary control (pump control) or primary and secondary control (pump and motor control). If a s

Arrangement whereby a mechanical pressure is compensated for by an opposing hydraulic pressure created by a separate power pack (Figure H 27) . The hydrostatic bearing is generally used when the inten

Arrangement whereby a mechanical pressure is largely compensated for by an opposing hydraulic pressure. The hydraulic pressure is generally removed from the system in such cases. Example: hydrostatica

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

Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, " hydropneumatic accumulator ") and, m

Device for converting mechanical energy (torque M, rotation speed n) into hydraulic energy (flow rate Q, pressure p). Displacement pumps are used in hydrostatic applications for this purpose. A flow r
