Piston motor
The radial piston motor tends to predominate with its special pneumatic motor variety. The piston motor supports high loads across all rotation speed ranges and is particularly suitable for low rotati
ISO
Worldwide association of national standards institutes whose technical committee TC 131 works on all standardisation tasks associated with fluid technology. The resulting ISO standards are either adop
Incremental position encoder
Encoder whereby a bar pattern ( incremental position measurement ) is applied to a disc. As this rotates, the angle of rotation is determined via the number of increments counted during the period of
Pulse generator
Device which gives out pulses with a prescribed frequency at the output when a signal is pending at the input.
Frequency analysis
Determination of the composition of noise in relation to individual frequencies. Normally the measurement is made in steps of one octave (frequency doubling, octave band).
Required filtration grade
In principle, filtering should as be fine as necessary, not as fine as possible. In general the filtration grade is defined by the manufacturer of the related device. These days this information is so
Spring assisted sealing elements
A sleeve made of certain elastomers (e.g. fluoroplastics) contains a spring made of stainless steel that provides defined, constant sealing forces (Figure F 2) . Spring assisted sealing elements are u
Pressure flow
Flow that is produced in the gap between two chambers with different pressures p 1 and p 2.
Pressure difference
Difference between two pressures p 1 and p 2 : If the pressure difference is the measured variable it is called the differential pressure p 1,2 (DIN 24 312).
Hydraulic fluids
Hydraulic fluids have the task of transporting hydraulic energy from the location of generation (pump) to the location of conversion ( cylinder , motor) with the minimum possible losses. They are also
