On compressors: Ratio of the absolute final pressure to the absolute inlet pressure on a compressor. The pressure ratio on a multi-stage compressor is given by the ratio of the absolute inlet pressure

Valves that trigger switching processes on reaching an adjustable pressure. A differentiation is made between: Shut-off valve The valve opens to the outlet on reaching a pilot pressure (example: pump

Device that, by applying pressure to a piston, indicates whether the pressure in the medium is above or below a pre-defined value (CETOP RP 100).

Constant pressure with which a device or a system can be loaded during the intended lifetime in defined operating conditions (DIN 24 312).

Adjustments of positive displacement machines.

Design category for seals with a pronounced lip. The main examples are grooved ring seals with one or two lips ( Figure L 23 ), as well as roof-shaped seals and lip seals — although the latter are not

which relies on the piezoresistive effect of semiconductors under a mechanical load. Here, as well as depending on the strain, the measured value is also highly dependent on the temperature. The measu

Hydraulic motor with a larger number of displacement units , which are pooled into two or three groups and can be switched in order to achieve different displacement and therefore different speeds. Th

A controller, in fluid technology must be configured through fine tuning of the various parameters (e.g. P-component, I-component, etc.) or for state controllers of the amplifiers such that the system
