Water-free, synthetically produced fire-resistant fluids. They rely on the following compounds: Phosphoric ester (HFD R), currently the most widely used HFD fluid; performs worst in terms of fire resi

Throttle is the general term used for a physical flow resistance. Throttle is therefore the generic term for orifice and nozzle . Flow resistances with a largely linear dependence of the flow rate on

Valve which protects the lines to a cylinder secured so that it can no longer make any undesired or hazardous movement in the event that the supply line breaks.Burst pipe protection is mainly used in

In hydraulic fluid removal of the air carried and separated out. This must take place at the highest point with the aid of bleed screws or bleed valves.

Filter, which separates contaminations primarily on the inside (bulk) of the filtering material. Filter elements with several layers are used for this and are made of metal powder (sintered filer or f

A floating measuring body is raised by the flow rate in a conical measuring pipe until a balance is reached between the weight of the floating body and the flow resistance ( Figure S 39 ). This means

Angled measuring device for determining the total pressure , i.e. the overall figure for the static and dynamic pressure associated with a fluid flowing at a subsonic rate. The pitot tube consists of

Elements to be mixed in with pressurised water ( HWBF ) to give the water lubricity and corrosion protection. They usually make up 2 to 5% of a hydraulic fluid. A distinction is made between three gro

Links the function commands provided by the programmed control with the feedback from the sensors in accordance with the logical instructions for control signals. This means, e.g., the linking of inde

The static behaviour of a continuously adjustable valve describes the connection between the input variable and the output variable of the valve for the stationary state after settling. This includes
