Controller on which the input and are analogue signals . Also controller with analogue, and with continuous and time-continuous , i.e. progressive input and output signals today often have a digital c

Process to monitor the operating state of a hydraulic system or individual devices with the aid of temperature and pressure measurements . It uses the hydraulic fluid to carry the information and is b

Fluid seal for rotating shafts that comprises two elements made of non-elastic materials that are pressed against each other by spring force. One element rotates with the shaft, while the other is mou

Range within which the viscosity of a hydraulic fluid satisfies the requirements placed on it. It is defined by operating conditions.

Reverse of the Vane pump principle , in which two vanes are adjustably arranged in the housing at an angle of 180°, which, together with two cams on the rotor, create two suction chambers and two pres

Pilot pressure below which a component adopts the 0 position.

Collective term for fluid and gaseous media. Here fluids is above all a common term for hydraulic fluids and compressed air.

Processing of digital signals (instead of analogue signals). Digital signal processing has experienced rapid growth due to the development of the microprocessor as a signal processing module. Digital

Valve that is in parallel with a hydraulic unit and that permits the pressure fluid to bypass this unit under certain circumstances. Example: Pre-loaded check valve that is in the secondary flow for a

Also called the delay time. It is the time, which the output signal of a 1st order delay element requires to reach 63% of the end value. After 3 · T 95 % and at 5 · T almost 100 % of the end value (Fi
