Sudden noise created when a flow rate is suddenly stopped as a valve closes or when the compression volume, e.g. of a cylinder meets the oil column in the feedback line at a high speed due to the sudd

Entirety of all deviations on the actual surface from the geometrically ideal surface. On viewing the surface, a differentiation is made between coarser and finer deviations. For exact differentiation

For the electric actuation of hydraulic devices on valves solenoids are used primarily in various versions as DC, AC or also as proportional solenoids . Electric stepper motors or DC control motors ar

Accumulator drive system , which supplies its consumers via two pipeline networks, one with low-pressure and one with high-pressure, in order to save energy. In hydraulic systems, the low-pressure lin

With proportional spool valves, the overlap/underlap at the individual control edges of the valve (overlap/underlap conditions) determine the flow rate signal characteristic curve ( Figure N 6 ) and t

Transmission parameter. The range of the torque multiplication is given by the ratio of the maximum to the minimum torque of a hydraulic motor or hydrostatic transmission : The magnitude of the multip

Control of the flow rate of a hydraulic system by flow resistances in general with the objective of controlling the velocity of a cylinder or motor. For this purpose flow valves , manually controlled

Arrangement of the Return line filter "in the secondary flow", i.e. the filter is placed parallel to a throttle so that only one part of the returning oil flow is filtered ( Figure T 7 ). This arrange

Displacement machine, in which two or three screw spindles engage one another such that the edges seal against one another and against the housing. In displacement areas between the housing and the sp
