A distinction is made between: pressure-controlled : Area between minimum and maximum flow rate as a function of the pressure difference (inlet pressure minus outlet pressure): Q = f (p) under stated

The accumulator precharge pressure (p0-> p0h) changes with the ratio of the increased or decreased temperature T0h to the original temperature T0. Calculate the accumulator pressure on temperature cha

Difference between the ideal and actual rotation speed of a hydraulic motor under given conditions. Motor slip is caused by the internal leakage of the motor, which depends on the pressure .

Opened control circuit.

Refers to the supply and discharge of the pressure fluid in pumps/motors through the inside of the displacement unit. For example, with valve plate controlled radial piston machines where the pistons

A differentiation is made between installation in the main flow , in the partial flow or in a separate circuit ( secondary flow ). Filters in the main flow filter the entire flow rate. These include s

External gear pump on which, for reasons of noise reduction, two pairs of gear wheels are used that are offset in relation to each other by half the tooth pitch. In this way the delivery flow pulsatio

If a signal is adjusted continuously or in steps, the term signal selector is used. As the reference variable is to be set such that the task variable reaches its setpoint, the signal selector for the

According to DIN-ISO 1219, the combination of electrical and hydraulic actuation via a solenoid-actuated pilot valve ( electro-hydraulic actuation ).

Theoretical preliminary work for the construction of a controller. An analysis is performed of the dynamic of the system. Then a search is conducted to find a controller that can provide this data and
