Losses in hydrostatic displacement machines are comprised of the leakage losses in the displacement elements and the control surfaces (summarised in the volumetric efficiency η Vol) and moment losses,

Transfer elements

Arrangement whereby a greater number of pipes for hydraulics, pneumatics and/or electrics can be connected or disconnected in one go ( Figure M 31 ). It must be set up in a way that allows a high numb

There are special boundary conditions for mobile machines (excavators, cranes, loaders, etc.). These conditions are due in part to the mobility, and in part to the tasks and environmental conditions.

Relationship between the weight of a system/input or output element and the power it transmits or provides. Given the very high force density , hydrostatic systems are much better than electric ones i

"Open loop"; because the term "control" applies to both ordinary controls and , the words "open loop" is added to designate an ordinary control (not involving feedback). Opposite: closed loop .

Disc-shaped piston with a vulcanised double pot seal or the like and combining the functions of a piston, piston guide and seal (Figure K 24) .
