The shape of a throttle largely defines the change in the throttle cross-section and therefore the characteristic of the flow. As (Figure D 89) shows, with a rectangular cross-section (a) there is a l

Generic term in fluid technology for hydraulic fluids ( hydraulics ).

HWBF hydraulic fluid where any elements to be mixed into the medium in order, for example, to improve lubricity and increase corrosion protection are added as very small droplets. Micro-emulsions are

Period of time, after which the outstanding instructions are reported (DIN 19 237).

Unwanted change of a physical variable over time due to the influence of temperature.

Sequential, i.e. step by step switching control whose internal switching conditions depend on external signals (e.g. feedback from the process). One characteristic of the staged clock control is that

Wear on a metallic surface caused by solid particles contained in a liquid jet approaching at a high speed. Particle jet erosion results in smooth surfaces, as if they had been polished.

State of a system at the end of the transition phase (settling), in which the which determine the function of the system remain constant over time.

The parameter of a signal , which carries the information. For example, the voltage is the signal parameter in the case of a continuous DC voltage. In the case of a frequency modulated AC voltage sign

As hoses must be elastic in order to fulfil their task as a moving line connection, consideration must be taken to ensure that they also react elastically to excess pressure from the inside. Hoses for
