Vane pumps operate according to the Positive displacement principle . The moving vanes, which are guided radially in a rotor and are supported in an eccentric stroke ring (stator), create an increasin

Fast, bistable memory element for saving 1 bit. A number of flip flops connected in series are used as a shift register.

Bistable switching element in which the switching state last used is retained also after the removal of the input signal (memory action).

Compressed air filters that can retain particles of dirt down to 0.01 μm. This includes fluid particles of this size (e.g. aerosols), and also bacteria and viruses.

The controllability of very small flow rates in continuously adjustable valves requires special measures on the control edges . In servo valves straight control edges with high precision are used (zer

Throttle valve that due to suitable formation of the control edge (e.g. by means of notches) has very good resolution in the low flow range.

An error is present if (a) feature(s) of a part is/are outside the defined limits or limit pattern (according to DIN 267). Not every error automatically signifies a defect on the machine (system) (DIN

Statement of the insensitivity to errors/failures of computers that must operate “non-stop”. Error tolerance is achieved by means of a redundant system tailored to the computer in which the sub-system
