Ring-shaped (loop) hydraulic fluid line to supply multiple consumers. Compared with a stub line, the loop line enables:
- a balanced supply of pressure, i.e. there are smaller pressure fluctuations and
- smaller pipe cross sections with the same flow rate or pressure drop.
Compressed air networks are often designed as a loop line. In hydraulic systems, loop lines are used, for example on ships and in large-scale water hydraulic systems.
