Feature on hydraulic pumps of piston and vane design on which the delivery flow follows an arbitrary defined setpoint in accordance with a reference variable s by regulating out the disturbance variab

The part of a filter that undertakes the actual filtering action. Filter elements are generally designed so they can be replaced easily and are disposed of after use (exception: metal filters). The ti

In accordance with ISO 1219-1 load-holding valves are classed in the group of pressure control valves. They prevent double-acting consumers (such as hydraulic cylinders and hydraulic motors) that have

Flow through a valve as determined by a given load and a specific signal. With continuously adjustable valves , the load flow is described in terms of the flow rate load function Q L=f(y,pL).

Pressure resulting from an external load (DIN 24 312).

Feedback of the load pressure in hydrostatic transmissions . Negative load pressure feedback increases damping for the drive, but without any influence on natural frequency or velocity amplification .

Measures which keep constant the level of what is passing through a throttle in terms of flow rate , regardless of the pressure difference which applies to it ( flow control valve ). Continuously adju

Pressure difference between the working openings at a management or . It is referred to as positive if the inlet pressure is higher than the return line pressure. With synchronizing cylinders , the lo

Laplace transformation is a method for solving linear differential equations with constant coefficients based on given initial conditions. It can also be used for fault functions which give the value

A serial bus line for data transmission within a locally restricted area is referred to as a LAN (or also an "inhouse net"). Local networks are the sole responsibility of the user and are restricted t
