Resistance of a liquid to changes in viscosity under shear stress (CETOP RP 100).

Disturbance variables in controls and are all external variables which impair the intended influences in a control or feedback control (DIN 19 226).

Fluid valve with binary behaviour, i.e. it moves from one switching position to another (e.g. Open – Closed) without adopting an intermediate position.

Oldest form of elastic seals . They can be used as two lip seals for sealing at the inner and outer ring (Figure N 9 a) or as a single-lip ring with an adhesive section for single-sided sealing. The s

Ability of a filter to retain specific test contamination in a hydraulic fluid with a specified contamination concentration under defined test conditions (CETOP RP 100). As the test method for filtrat

Piloted valves

Term used for operating elements (cylinders, motors, swivel motors ), which are controlled by a continuously adjustable valve . We sometimes use this term in place of servo cylinder .

Losses arising in hydraulic pumps and motors when the housing is full of oil and the components are moving around inside. These are dependent on the rotation speed and — particularly during idling — m

Changing the stationary characteristic curve for a device by modifying the input signal in order to compensate for non-linearities , reduce hysteresis and the like. This kind of correction can involve
