Volume that does not contribute to the system performance, but must be placed under pressure as the working cycle changes. The volume increase associated with this changes the natural frequency of the

In many cases, the voltage signals obtained during electrical measuring of mechanical variables cannot undergo further processing directly in the signal section of a control . They need to be prepared

Another form of actuation, apart from the main form of actuation, whereby the energy is not dependent on that of the main form of actuation. In general, various methods of manual operation are availab

Controlled valve that opens to the outlet and as a rule has the task of allowing the compression volume to escape in a controlled manner until the pressure in the chamber has dropped to a specific val

Expression frequently used for a pressure controller for variable pumps.

Hydraulically actuated 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.

On continuously adjustable pressure valves : dependency of the pressure on the flow rate with the input signal as a parameter (E DIN 24 311) (Figure D 81) .

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 .
