A programming notation in which the letter of the alphabet and the numbers from 0 to 9 are used.

Axial piston pumps have several pistons that are arranged parallel to the drive shaft. They are available as either variable pumps or constant pumps. Axial piston variable pumps operate, for example,

Procedure for the exact, corrective adjustment of the existing actual values on devices or components to a stipulated, required value. Examples: Adjusting the ohmic resistance or the inductance of coi

External gear pump with compensation of the radial and axial play to reduce the gaps with increasing pressure . This compensation is achieved by means of suitably shaped and arranged compression sprin

Pressure actuation of a (normally larger) valve using a suitable (normally small) valve, which is mechanically or electrically actuated.

Element in a in which the signal of the correcting variable is formed at the output from the controller output signal at the input This is used to modulate the subsequent . The regulator is omitted if

Hydraulic pump with pistons arranged alongside one another and perpendicular to the drive shaft Piston ( Figure R 24 ). They are preferably made as single-piston pumps (also for manual operation) or a

Measuring instrument which outputs the measured value for the variable measured ( measured variable ). It either serves as a visible output or an indirect output. Many signal output elements still fea

Device for converting mechanical energy (torque M, rotation speed n) into hydraulic energy (flow rate Q, pressure p). Displacement pumps are used in hydrostatic applications for this purpose. A flow r

Freely moving indicator on a pressure gauge , which has the task of displaying the maximum pressure incurred in a system. The drag indicator can be reset using a control knob.
