rises and at low temperatures it approaches the pour point ( Figure V 31 ). This viscosity change can reach a few orders of magnitude. Its characteristic curve is equivalent to an exponential function [...] devices: Very high viscosity impairs the suction behaviour of the pumps (danger of cavitation) and can cause switching delays. Very low viscosity worsens the lubricity of the oil and increases the leakage

lasts. Cams are attached to moving supports (e.g. discs) or to fixed cam rails in such a way that they can be moved. They support precise switching, although they are not very flexible for adjustment purposes

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. The system of

removal of energy by throttling, leakage (bypass) or also friction with the special feature that it can only be activated if oscillations occur. The steady-state system behaviour is in general hardly affected

using operators, time and storage elements to form binary output signals (DIN 19 237). Binary controls can be roughly divided into logic control systems and sequence control systems (Figure B 16) .

precisely defined gap through which the displaced air escapes (Figure D 4) . On moving out the air can then flow in again unhindered. This means a damping seal should have the action of a with a defined

digital systems a gearwheel generates pulses in a coil and these pulses are counted (Figure D 40) . They can operate as accurately as necessary via the number of teeth and are very economical.

full pump delivery flow from the constant pump passes through all the valves . Very high flow losses can occur with open centre systems. Opposite: closed centre system .

Cylinder design that is equipped with several, mostly binary tiered pistons that can be operated in any combination. Therefore with n pistons 2n-1 positions are obtained with a positioning accuracy that

amplifier. Measuring amplifiers with carrier frequency are required for inductive transducers and can also be used in resistive systems.
