Indirect actuation
pilot actuation ). In addition, the main device and the operating element (generally a pilot valve ) can be separated from each other, making remote controls an option.
SAE flange
PSI (210/420 bar), nominal widths of 15 to 50 and fastening screws with UNC threads. The SAE flange can be used as a two-part flange to connect pipelines to non-split counterfaces or as a one-part flange
Wheel motor
Hydraulic motor , which can be integrated directly into the wheels of a vehicle. This produces a direct transfer of the force without interposing a manual transition, cardan shaft and differential gear
Hamming distance d
string with a Hamming distance of d = 2 offers greater transmission security, since single errors can be detected and corrected. Only double errors will cause something to look like another code word.
Signal forms
digital or binary character. In addition, they may have a continuous value, i.e. the signal parameter can take on all values within an interval; have a discrete value, i.e. the signal parameter, e.g. a DC
Pressure controller for a variable pump
al valve ), to reduce the power losses as a consequence of internal leakage the response pressure can be pre-selected on a case-by-case basis (see Pressure-flow (p-Q) control of a pump ).
Signal output element
or sensors, etc. Indirect signal output elements either output the measured value in a form which can only be identified with auxiliary equipment or special knowledge or they relay the measured value directly
Contamination of the hydraulic fluid
Contamination of the hydraulic fluid of a hydraulic system. It can be caused by solid particles and/or dissolved foreign matter, by mixing with foreign liquids, or by air entering the hydraulic fluid.
Internal gear pump
delivery flow pulsation and are therefore quiet during operation. With axial play compensation they can achieve average pressures of up to around 160 bar, while 300 to 320 bar is possible with combined axial
Types of motion of cylinders
the drive: Transport motion : with the highest force required on accelerating the load. The velocity can mostly not be maintained accurately. Example: block valve. Power motion : required force over the entire
