Slim pressure rods such as thin piston rods may buckle outwards if the compressive force F exceeds a permissible value (Figure K 12) . This value is referred to as the buckling force F K. Cylinders wi

HFB fluid

For fluid valves there are a number of actuation types: Manual actuation: Actuation using a hand or foot (including manual override). Mechanical actuation using levers, plungers and/or rollers and spr

In general : Device, which reduces the pressure (pulsation) fluctuations and therefore reduces the noise produced in connection with this, without preventing the transport of the fluid. In hydraulics

Viscosity of a hydraulic fluid at a defined temperature. This used to be +50°C according to DIN 51 502 and has been +40°C for a number of years now according to ISO 3448 (DIN 51 519). It is essential

Since actual fluids are compressible, they behave like a spring when pressure is applied to them: the higher the pressure, the more they are compressed and the smaller their volume becomes. The spring

Code in which the character string is formed based on defined specifications that makes it possible to detect deviations on these devices caused by malfunctions. The fault detection codes are redundan

The expression characterises the interaction of a throttle function ( throttle valve , continuous directional valve) with a (control throttle) that provides a load pressure independent flow rate with

Ratio of the areas of valves subjected to the control pressure (hydraulic or pneumatic) Valve . The control surface ratio plays a particularly vital role in the case of 2-way plug-in valves ( Figure S

Estimated time or time determined on similar systems that a filter element can be used before it must be replaced. The operating life is dependent on the filter selected, the amount of contamination t
