Provides information on the magnitude of the Δp of directional and check valves depending on the flow rate Q (Figure D 78) . The pressure drop-flow rate chart is an important parameter for assessing a

In position measurement with ultrasound (US), a US signal is issued, which is reflected by the moving body. The duration of the system measured in this way is proportional to the distance travelled. A

On hydrostatic transmissions the transmission efficiency comprises the total efficiency of the pump and motor: From here the total power loss is obtained:

This term covers all combinations of electrical (electronic) signal processing with hydraulic drives. These combinations can be divided into three groups: Electro-hydraulic technology in which hydraul
