Generic term for the methods and processes to accept measurement information and issue signals as the bearers of prepared information tailored to a given task, e.g. managing a technical process. Senso

Periodic change in the pressure in a device from values above atmospheric pressure to values below atmospheric pressure (e.g. on pumps between the suction and pressure phase).

Changes in the pressure due to a change in the inlet pressure with a given flow.

Valve with a rotating shaft as the control element that houses the control bores (Figure D 39) . Rotary valve are only used infrequently because their actuation is difficult to automate.

Distance covered by a piston from the starting point to an end point and back to the starting point. Forward stroke : extension of a piston (mostly the same as the working stroke), Return stroke : ret

Triggers an actual damping process that stabilises the drive as the load pressure changes. Damping devices can operate mechano-hydraulically as throttle valves or bypass valves or electro-mechanically

"Blowing past" a piston seal. With large pressure gradients it can occur that the seal is not pressed against the sealing surface, instead it is pressed into the grove (Figure B 21) .

Closed loop structure in a binary system that contains at least one binary memory element.

Information defining the lowest required pressure and the highest permissible pressure for the safe operation of a device (system).

Sealing systems in which the sealing gap between two sealing surfaces is sealed to a greater or lesser extent by a sealing element that touches both surfaces. The related deformation is applied by scr
