Compares the value of an input variable with a limit. If this limit is exceeded or dropped below, the limit signal changes (DIN 19 237).

the increased sensitivity to leakage with operating conditions that are becoming harder at the same time: a situation that is becoming increasingly difficult with individual seals (Figure D 15) . The

which only separates off impurities at the surface of the filter element. Surface filters are designed with pores (gap) of a similar size, which means they can retain certain sizes of particle almost completely [...] only have a small dirt holding capacity , which significantly reduces their service life compared with volume (bulk) filters . Surface filters are manufactured using thin fabric, mainly consisting of metal

several, often with different materials, are assembled to form roof-shaped seal sets (Figure D 1) . In principle a differentiation is made between two forms: In form (a) the limbs are in contact with each other

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 springs

pilot valve is mostly directly on the main valve (Figure E 19) . With this combination it is also possible to control large valves with low electrical power (gain factor up to 105), which can be undertaken

filling. It is appropriate to combine the filler filter with the flushing power pack , as otherwise the filling process will take too long with cold oil.

encoder based on the principle of the rotating field that contains a rotor and a stator with a number of windings and with an output voltage that corresponds to the angular position of the rotor. The stator

pressure difference (DIN 3320). With pressure-limiting valves under direct control, the size of the opening pressure is adjusted by means of the preload associated with the compression springs. In general

recovery energy used: Utilisation of kinetic energy between moving masses by using hydraulic motors with secondary regulation. The energy recovered is collected in a hydraulic accumulator (on electrical [...] example: vehicle drive). Utilisation of the potential energy of lowering masses via hydraulic motors with secondary regulation (b) ; example: crane. Utilisation of dissipated heat via heat exchangers.
