Male fitting
Pipe connection that can be undone and that is designed at one end to screw into a device bore ( pipe fitting ).
Damped natural oscillation
The damped natural oscillation of a system (e.g. spring-mass system or control circuit) is formed by oscillations or aperiodic movements that the system makes after external stimuli cease, i.e. when t
Pressure control
Change in the pressure in a device or a system as a function of pre-defined control signals. The pressure control can be undertaken by switching processes or continuously.
Digital circuitry
Connection together of digital modules with simple or complex functions ( integrated circuits ) to form complete controls.
Input signal
Signal acting directly from the exterior on the signal processing or on an input element signal (DIN 19 237).
Actuator
This is generally synonymous with a . In the event of movement control, the actuator converts the electrical signals of a controller into mechanical work. One example of this is the opening and closin
Nominal force of a cylinder
The force produced in theory by the piston rod, ignoring any friction losses, when the cylinder is operating at nominal pressure . As far as single-acting cylinders with spring return are concerned, t
Fabric materials
Fabric group for seals that comprise textile fabrics that have been impregnated with elastomer components. The seals manufactured from this material are suitable for very high pressures due to their h
Bursting pressure
Static pressure at which a pipe or pipe connection is destroyed such that hydraulic fluid escapes (DIN 24 312). This definition should also be applied to the filter bursting pressure for the filter ho
Contamination class
The particle size of the contamination in a hydraulic fluid is spread over a wide area. In view of this fact, contamination classes have been created that set out the contamination in SAE-ASTM-AIA and
