Return line
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
Return line filter
Filter to be installed into the return line of a system. The housing is designed for pressures of around 20 to 30 bar. Return line filters – regardless of the size of the pump flow rate – must be sele
Return line pressure
Pressure created by flow resistances which must be overcome when feeding back the pressure fluid (to the tank).
Retention rate
Filter cumulative efficiency
Feedback
In general : Determination of a physical variable of a process and further use at another point. This is generally a feedback control, but may also be data collection, for example. In control technolo
Feedback system for continuously adjustable valves
Continuously adjustable valves generally have internal feedback of force and position feedback, which monitor the position in a corresponding to ensure the most precise possible correlation between th
Recirculation
Some of the oil film stuck to the piston shaft at the outlet of a cylinder is scraped off when the piston is inserted (results in leakage even in the case of an intact seal), while the other part is f
Drag flow
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 int
Drag flow pressure
Pressure, which builds up under certain constraints in front of a piston rod seal and which can reach several times the nominal pressure of the system. The drag flow pressure is caused by the drag flo
