Throttle valve that is designed as a screw-in cartridge.

The power input P of a pump is calculated from the pressure p and the flow Q as well as from the efficiency factor η of the pump. Alternatively, the power input can also be calculated from the torque

The heating ΔT of an oil volume V (without heat dissipation) is calculated from the supplied power PH, the period Δt of power supply, the specific heat capacity of the medium c (~1.88 kJ/(kg*K) for Oi

Cylinders whose stroke is significantly shorter than the piston diameter ( Figure K 41 ). Short stroke cylinders are used in hydraulics for things like tensioning or closing processes.

Illustration of an analogue signal profile using the relative duration of a rectangular pulse within a specified cycle (period), which must become shorter as the process becomes more dynamic ( Figure

Modified HLPD oils that only take on (hold) a water content of 1 to 2%, but separate larger water quantities –– like any normal mineral oil . The stabilised hydraulic oils therefore only slightly redu

Hydraulic pump/motor with two or more gears working together in one housing. They may take the form of an external geared pump/motor , an internal geared pump/motor or an annular gear pump/motor .

Design of the necessary form of control edges in hydraulic valves necessary for the respectively desired manner of influencing the flow rate ( fine control ).

Filter cumulative efficiency

Hydraulic valve which creates the difference between the setpoint and actual value and also releases a flow rate proportional to the difference. To this end, the control unit for the valve is connecte
