Limit load control
(engine loading), which results in a reduction in the variable pressure at the pump adjustment and therefore causes the pump to pivot back. [...] machinery, i.e. the movement velocity of the machine (corresponds to the flow rate to the variable pump ) is reduced automatically to the advantage of the other drives if the combustion engine would otherwise
Flush valve
directional valve that ensures in a closed circuit that the oil brought into the circuit by the Flushing pump is once again flushed out on the respective low-pressure side.
Unloading valve
pressure exceeds a value defined by the adjusting spring. An unloading valve can also be used as a pump idle circulation valve .
Durchflussverteilung (Flow Sharing)
independent of the pump capacity. With the help of pressure compensation, the oil flow to the consumers is proportionally distributed, independent of the total delivery line of the pump. And this is also [...] system is undersupplied by the pump. Each valve section has its maximum flow rate. Without flow distribution, the fluid will choose the path of least resistance if the pump cannot provide the required flow
MH engine (bent-axis machine)
classification characteristic based on drive kinematics for axial piston bent-axis (axial piston) pump or motors where the piston rods take the torque-free cylinder drum with them.
Centre position
connected with each other and with the process ( b ), pump direction switching in the centre position; working ports A and B are closed, the pump port is connected to the tank ( c ).
Force-time diagram
load (e.g. a cylinder) over time. The force-time diagram is used when deciding the dimensions for the pump ( Figure K 36 ).
Hydrostatic transmission with separated primary/secondary
Also termed open transmission. hydrostatic transmission on which the pump and motor operate separated from each other. Pipes and hose lines make the hydraulic connection (Figure F 10) . Opposite: integral
Breather filter
Filter on the hydraulic fluid tank that filters the air flowing in as the pump draws fluid to prevent contamination by this route. Its filtration grade should correspond to that of the oil filter.
Displacement flow
Flow rate coming from the pump, which a hydraulic motor takes on, depending on its displacement volume (geometric displacement). It is calculated as the product of the displacement and the rotation speed
